Dog deworming schedule for India: puppies, adults, dosage per kg and what the tablets treat

What the three guidelines say a dog deworming schedule should be

A dog deworming schedule, in the three guidelines that matter for India, starts at 2 weeks of age and repeats every 2 weeks until 8 weeks, and then the guidelines part company: TroCCAP, written for the tropics, says monthly for life; ESCCAP, written for Europe, sets an adult interval of 1 to 12 times a year by risk group; AAHA says monthly, year-round, for the life of the dog. Their exact words are quoted below, because clinic websites and pharmacy blogs paraphrase them into something looser.

TroCCAP is the guideline written for climates like India's. Its second edition, 17 March 2019, says that "puppies should be dewormed fortnightly until 8 weeks of age, preferably with a product with activity against adults and immature worms (e.g., moxidectin, emodepside) and then monthly thereafter. Adults dogs should be dewormed monthly", more often "in cases of heavy burdens";. Its roundworm chapter dates the start: "at 2 weeks of age (to prevent vertically acquired infections becoming patent) and then every 2 weeks until 8 weeks of age. Treat the dam at the same time";. It also asks that "dogs should be tested for gastrointestinal parasites at least once every 3 months";.

ESCCAP governs Europe, and its seventh edition, June 2025, works by risk group. Puppies are treated "for the first time on the 14th day after birth, then every 2 weeks until 2 weeks after weaning. If there is an ongoing increased risk of infection (e.g. puppy playgroups), monthly treatments up to six months of age";. Adults fall into risk groups A to D, from "treat 1-2 times a year against intestinal nematodes or carry out faecal examination and treat according to findings" for a dog kept entirely indoors, to "treat 4-12 times a year" plus "12 times a year against tapeworms" for a roaming dog that eats raw meat, prey, slugs or snails. Its floor: when risk "cannot be clearly assessed, the dog should be dewormed or faeces examined at least 4 times a year", because "studies have shown that 1-3 annual dewormings do not provide sufficient protection";.

AAHA, the American life stage guideline of 2019, says "deworming beginning as soon as 2 wk of age and repeated every 2 wk until routine monthly treatment is initiated", and that adult infections "can be controlled by continuing monthly deworming year-round for the life of the dog", with a faecal examination "1-4 times/yr depending on lifestyle and use of preventives";.

Where the three agree, and where they split

Which one governs an Indian dog today is TroCCAP, the tropical guideline, because it alone is written for a hot, humid environment where worm eggs and larvae survive in soil for months, and because ESCCAP and AAHA both defer to local risk. Where all three agree the answer is settled: first dose at 2 weeks, every 2 weeks to 8 weeks, mother treated the same day American Animal Hospital Association. Where they disagree, on the adult interval, this page prints all four figures and your nearby vet decides with a faecal test in hand. One inconsistency sits inside TroCCAP itself: its hookworm chapter says that after 8 weeks "dogs should be dewormed fortnightly, or if using moxidectin, then monthly", while its general recommendations say monthly. The Chandigarh Administration's table thins adults to every 3 months and cites no source.

Puppy deworming schedule for India, week by week

A puppy deworming schedule for India runs from 2 weeks of age to 6 months: doses at 2, 4, 6 and 8 weeks, then monthly, with the mother treated on the same day as the first dose and each dose given a few days before a vaccine visit rather than on it. The first dose is early because Toxocara canis and Ancylostoma caninum pass from the bitch to the pups in the womb and in milk, and TroCCAP records hookworm disease in puppies "as young as 10 days old";.

1. Week 2. First dose, and the dam on the same day, in TroCCAP's words "at 2 weeks of age (to prevent vertically acquired infections becoming patent)";. At this age the product is a suspension, not a tablet: Kiwof Puppy is dosed at 1 ml per kg of body weight and its leaflet says treatment "should be started at 2 weeks of age and should be performed repeatedly at suitable intervals (for example every two weeks) until weaning";. Virbac's Milpro tablet is labelled for puppies "from 2 weeks of age and 0.5 kg body weight";.
2. Week 4. Second dose. The Chandigarh department's table puts its second dose at 1 month; TroCCAP's every-2-weeks rule puts it here.
3. Week 6. Third dose, timed 3 to 5 days before the first vaccine visit. Deworming sits between the shots on the dog vaccination schedule in India, and that guide quotes the vaccine leaflet warning that a parasitised puppy may not mount a full immune response.
4. Week 8. Fourth dose, the last of the fortnightly series under TroCCAP and AAHA. ESCCAP runs the fortnightly series "until 2 weeks after weaning", which for a puppy weaned at 6 to 8 weeks lands in the same place.
5. Weeks 10 and 12. Monthly from here under TroCCAP and AAHA. Virbac India's own label keeps the fortnightly rhythm a little longer, "every 2 weeks until the age of 10-12 weeks and then monthly up to 6 months of age, if there is an increased risk of infection", and the Kiwof Puppy leaflet says "every two weeks till 3 months of age";. Weigh the puppy at every dose; a Labrador puppy can double its weight between two doses.
6. Months 3 to 6. Monthly, on every schedule opened for this page: TroCCAP, AAHA, ESCCAP where risk continues, the Chandigarh table ("every month up to the age of 6 months") and the Kiwof leaflet ("every month from 3 to 6 months of age";) American Animal Hospital Association ESCCAP Guideline 01 Animal Husbandry and Fisheries Department Sava Healthcare Limited.
7. After 6 months. The adult schedule, which is where the sources split and the next section takes over.

The calendar is dense because of biology, not caution. TroCCAP's roundworm chapter says heavy infections "via the transplacental route may result in pneumonia and acute death owing to enteritis and gastrointestinal blockage as early as 10 days of age";. The hookworm pre-patent period is "2 to 4 weeks depending on site of infection", which is why a dose every 2 weeks catches each generation before it lays eggs.

Three Indian sources print their own puppy calendars; they agree on the start and disagree on the taper. The Chandigarh department reads 2 weeks, 1 month, "every month up to the age of 6 months", "every 2 months up to the age of 1 year", then "at an interval of 3 months in case of adults";. The Kiwof Puppy leaflet reads every 2 weeks to 3 months, monthly to 6 months, "every 3 months after age of 6 months";. Virbac India's Milpro page reads every 2 weeks to 10 or 12 weeks, monthly to 6 months where risk continues, then a frequency "customised by your veterinarian". None cites a guideline, and all three taper further than TroCCAP.

A puppy bought or adopted in Bengaluru, Kolkata or any other Indian city often arrives with no record. The Haryana study of 310 pet and semi-pet dogs found deworming status among the factors associated with carrying a zoonotic gut nematode, and an Indian Pariah Dog puppy lifted off a street comes from the environment the 411-dog survey describes, hookworm in 39.1 percent of Delhi dogs and 48.8 percent of Mumbai dogs. Treat an undocumented puppy as unwormed, dose it the day it comes home, and restart the calendar from its age.

How often to deworm an adult dog in India: monthly, quarterly or by risk

An adult dog in India is dewormed monthly under TroCCAP, every 3 months under the Chandigarh department's schedule and the Kiwof leaflet, and 1 to 12 times a year under ESCCAP depending on its risk group, so the honest answer is a risk assessment your nearby vet makes with a faecal test every 3 months, not one number. The four figures are printed here with their reasons, and the reasons are what let you place your own dog.

ESCCAP's risk assessment translates to Indian homes without change. Risk group A is a dog that "lives exclusively indoors or has very limited access to the outdoors i.e. it has no direct contact with other dogs and has no access to parks or gardens" and eats no raw meat: treated or tested 1 to 2 times a year. Group B has "regular access to the outdoors" or is "often free to roam without supervision": 4 times a year. Groups C and D add raw meat, offal, prey, slugs or snails: 4 to 12 times a year, with tapeworm treatment up to 12 times a year. One household rule sits outside the groups: dogs "sharing homes with small children (below 5-6 years), immunocompromised or elderly individuals" get "planned deworming once a month or examine faecal samples once a month";.

TroCCAP's reasoning for monthly dosing is the environment, and India is the environment it was written for. It places Ancylostoma ceylanicum, the hookworm that matures in people, in "the wet tropics and subtropics of Southeast Asia, China, India, and Oceania", and asks for daily faeces removal and disinfected surfaces because eggs and larvae stay viable in warm soil. A pooled analysis of 14 Indian soil surveys found Toxocara eggs in 11.26 percent of public-place samples. A dog that walks an Indian street is, in ESCCAP's terms, never in group A.

• An apartment dog carried to a terrace and back, no street contact, no raw meat: ESCCAP group A, 1 to 2 doses or faecal tests a year; TroCCAP still says monthly in the tropics. Most Indian vets land on quarterly, the Chandigarh figure.
• A dog walked daily on a street in Delhi, Pune, Hyderabad or Chennai, or in a park shared with free-ranging dogs: ESCCAP group B at least, 4 times a year, and group C if it scavenges; TroCCAP monthly. The Haryana study found contact with stray dogs among the factors associated with infection in pet dogs, and a history of eating non-food matter (allotriophagia) the major risk factor on multivariate analysis.
• A dog fed raw meat or offal, or kept where livestock are slaughtered: ESCCAP says treat against tapeworms every 4 weeks unless the meat is heated for 10 minutes to a core of 65 degrees C or frozen for a week at minus 17 to minus 20 degrees C; TroCCAP says praziquantel at 6-weekly intervals in Echinococcus-endemic areas, which it names as including northern India.
• A dog in a home with a child under 5, a pregnant woman, an elderly or immunocompromised person: monthly dosing or a monthly faecal test under ESCCAP; monthly under TroCCAP.
• A dog already on a monthly preventative, a milbemycin or moxidectin combination chew for ticks, fleas and heartworm: the roundworm and hookworm cover is built in, so what remains is a praziquantel dose for tapeworm at the tapeworm interval above, and a faecal test at least every 3 months to check the product is working ESCCAP Guideline 01. Tick and flea products are a separate calendar that peaks with the monsoon, covered on the dog ticks in India guide.
• A kennel, breeding or boarding dog: ESCCAP says planned deworming once a month or a faecal sample every 4 weeks; TroCCAP says every dog in a household or kennel is treated on the same day.

The disagreement is published here rather than averaged. TroCCAP and AAHA say monthly for life American Animal Hospital Association; the Chandigarh Administration and the Kiwof leaflet say every 3 months Sava Healthcare Limited; ESCCAP says whatever the risk group says, never fewer than 4 a year when in doubt. What no guideline supports is the once or twice a year habit, which ESCCAP states outright does not protect. A quarterly faecal test is the cheapest way to learn which interval your dog needs, and your nearby vet, who knows the local worm pressure, decides.

Deworming a pregnant or nursing bitch: what ESCCAP and TroCCAP allow

A pregnant bitch is dewormed on a veterinary prescription only, because the protocols that reduce transmission to the pups are off-label in most countries: ESCCAP allows "macrocyclic lactones around the 40th and 55th day of pregnancy or fenbendazole daily from the 40th day of pregnancy until the 2nd day after delivery", and TroCCAP lists a near-identical fenbendazole course while stating that it "does not recommend the off-label (extra-label) use of drugs"; Tropical Council for Companion Animal…. The nursing bitch is simpler: she is treated on the day her puppies get their first dose.

The reason a pregnant bitch matters is arrested larvae. TroCCAP explains that in adult dogs "there is a high probability that T. canis infection will result in somatic migration with larvae in the tissues. Therefore, an absence of T. canis eggs in adult dogs does not rule out infection, as arrested larvae may re-activate during pregnancy to infect pups in-utero";. A clean faecal test before mating does not settle the question, which is why the guidelines treat the pregnancy itself.

• Fenbendazole 50 mg/kg daily, day 40 of gestation to 14 days post-whelping, the protocol TroCCAP cites for both Toxocara canis and Ancylostoma caninum; ESCCAP's version stops on the second day after delivery.
• Topical selamectin 6 mg/kg at 40 and 10 days before whelping and 10 and 40 days after, cited by TroCCAP for roundworm.
• Ivermectin by injection at 300 micrograms per kg on days 0, 30 and 60 of pregnancy plus 10 days after whelping, cited by TroCCAP, and the one with the MDR1 caution attached for herding breeds.
• A spot-on of imidacloprid 10 percent plus moxidectin 2.5 percent at day 56 of gestation, cited by TroCCAP for hookworm.

Every one of those is off-label, and TroCCAP is blunt about where responsibility sits: "the decision of using off-label drugs or protocols should rely on the recommendation of the veterinary practitioner in charge", and "the responsibility for any adverse event related to the off-label use of drugs and doses lies with the prescribing veterinarian";. The Indian leaflet says it in fewer words: "Consult a Veterinarian before treating pregnant animals for roundworms", "Do not exceed recommended dose when treating pregnant bitches", "The product may be used during lactation";.

For the lactating bitch the two guidelines agree. ESCCAP: "Deworm at the first treatment of puppies (2 weeks after delivery)";. TroCCAP: "Treat the dam at the same time" as the 2-week puppy dose. She then follows the adult schedule for her risk group, and the whelping area gets the daily faeces removal TroCCAP asks for everywhere else.

Dog deworming tablet dosage per kg, by active ingredient, with Indian prices

Dog deworming tablet dosage per kg is set by the active ingredient, not the brand: praziquantel 5 mg/kg, pyrantel 5 mg/kg as base (14.4 mg/kg as pyrantel pamoate on Indian labels), febantel 15 mg/kg, fenbendazole 50 mg/kg on 3 consecutive days, milbemycin oxime 0.5 mg/kg and oral ivermectin 0.2 mg/kg Sava Healthcare Limited. That arithmetic is why an Indian praziquantel-pyrantel-febantel tablet is dosed at one tablet per 10 kg, and why the tablet has to be matched to the dog's weight on the day, not to its breed.

Indian prices through the exchange-rate test

Both prices pass the exchange-rate test this site runs on every rupee figure: Rs 488 divided by 84.38 is 5.78 and by 74 is 6.59; Rs 813 divided by 84.38 is 9.63 and by 74 is 10.99. Neither lands on a dollar price a shop would print, so both are rupee-native figures from one Indian retailer on one day Supertails, Drontal Plus Dog Dewormer Tasty…. Per 10 kg that is about Rs 49 for Kiwof Plus and Rs 136 for Drontal Plus, so a 30 kg Labrador costs roughly Rs 146 or Rs 407 a treatment. Two manufacturer gaps are declared rather than papered over. Elanco has no Indian Drontal page that could be opened, so the Drontal one-tablet-per-10 kg figure rests on the retailer's listing and on the identical actives in the Kiwof leaflet Sava Healthcare Limited. MSD Animal Health India's Panacur pages give fenbendazole doses for cattle, buffaloes, sheep, goats and horses and no dog dose, so the 50 mg/kg for 3 days above is TroCCAP's figure and a dog course is a vet's prescription.

The Kiwof leaflet's weight bands show what one tablet per 10 kg means: over 3 to 5 kg half a tablet, over 5 to 10 kg one, over 10 to 15 kg one and a half, over 15 to 20 kg two, over 25 to 30 kg three, over 35 to 40 kg four; Kiwof Plus XL is one tablet per 35 kg Savavet, Kiwof product page: composition. The leaflet answers two questions the search box asks. On food: "The tablets can be given directly to the dog or disguised in food. No starvation is needed before or after treatment". On repeating: "For routine treatment a single dose is recommended. In the event of heavy roundworm infestation, a repeat dose should be given after 14 days";. Virbac describes Milpro as a broad-spectrum dewormer with a "highly palatable meat flavour", "scored on both sides, allowing you to easily divide them for smaller pets";. Side effects, on the same leaflet: "None reported. Vomiting was reported in some cases", and wash your hands after dosing.

The MDR1 caution for collies and herding breeds

The MDR1 caution is a line in TroCCAP's treatment principles: "Caution should be applied when using off-label macrocyclic lactones, especially in dogs with the ABCB1 (MDR1) gene mutation (e.g. Collies). Toxicity is also dependent on dose and route of administration, with topical application being generally better tolerated than oral and injectable ones";. Washington State University, whose laboratory identified the mutation, gives approximate breed frequencies: Collie 70 percent, Australian Shepherd 50 percent, Shetland Sheepdog 15 percent, German Shepherd 10 percent, herding-breed crosses 10 percent, mixed breeds 5 percent. Its problem-drug list says label-dose milbemycin and moxidectin products, and Heartgard's label ivermectin dose, tested safe in MDR1 dogs, but "for other formulations of ivermectin contact MDR1Caddie for dosing recommendations";. In India the risk is livestock or injectable ivermectin given off-label to a Rough Collie, an Australian Shepherd or a German Shepherd at many times TroCCAP's 0.2 mg/kg. Praziquantel, pyrantel, febantel and fenbendazole are not macrocyclic lactones and are not on the WSU list; for a herding breed or collie cross they are the plain choice unless a test clears the dog.

The zoonotic case: Toxocara, hookworm and Echinococcus in an Indian household

Three dog worms reach people in India, and each has an Indian denominator: Toxocara canis, whose eggs were found in a pooled 11.26 percent of soil samples across 14 Indian surveys; hookworm, in 71.3 percent of stray dogs sampled in Sikkim and 48.8 percent in Mumbai, including the human-infecting Ancylostoma ceylanicum; and Echinococcus granulosus, with 1,124 of 3,929 suspected patients seropositive at one north Indian centre over 12 years. Deworming a dog on schedule is the household's share of that zoonotic risk, and the law puts it on the owner.

Toxocara canis reaches people through eggs in soil, not through the dog directly, which is why the soil figure matters. TroCCAP: "Ingestion of embryonated T. canis eggs in the environment may produce covert, ocular or visceral larva migrans. Children are most at risk owing to their behaviour", and larvae "may enter the eye and its vasculature causing blindness or decreased vision". The Indian meta-analysis pooled 14 soil surveys from 1985 to 2017: Toxocara eggs in 11.26 percent of samples, 95 percent confidence interval 7.59 to 15.54, single studies from 2.11 to 31.0 percent. Toxocara canis was also the roundworm confirmed by cox1 sequencing in the Haryana pet-dog study, where 77 of 310 faecal samples, 24.85 percent, carried a zoonotic nematode.

Hookworm is the most common worm in Indian dogs and the one with a species that matures in people. The 411-dog survey across Sikkim, Mumbai, Delhi and Ladakh found it at 71.3 percent in Sikkim, 48.8 percent in Mumbai and 39.1 percent in Delhi, and PCR showed Ancylostoma ceylanicum and Ancylostoma caninum "to occur sympatrically" in Sikkim and Mumbai, an expansion of "this emerging zoonosis" to the west. On the human side, a pilot study across nine villages of Meghalaya detected Ancylostoma ceylanicum in 2.8 percent of people tested by species-specific PCR. In the Haryana pet dogs, 73 of 77 positive samples were Ancylostoma, and deworming status, contact with stray dogs and housing type were all associated with infection. Larvae also enter through skin, the route TroCCAP lists as "percutaneous", which is a barefoot child on soil where a dog has defecated.

Echinococcus granulosus is the one the dog carries without any sign. TroCCAP: "The parasite is of no clinical significance in dogs, but eggs passed by dogs infect humans and livestock to produce hydatid cysts in visceral organs"; it is "highly endemic in cooler regions of the sub-tropics (e.g. northern India, Southern Brazil), especially in rural areas where offal is readily accessible to farm and community dogs", and "eggs stick to dogs' coat and are infective immediately upon defaecation". The Indian numbers: at a north Indian tertiary centre, 1,124 of 3,929 suspected patients tested from 2004 to 2015 were seropositive, 28.6 percent, up from 15.0 percent in the same laboratory's 1984 to 2003 series; in a systematic random sample of 1,429 symptom-free people across Kashmir, 72, or 5.03 percent, carried hydatid IgG, with "rural residence and contact with dogs" the risk factors. In the four-city dog survey, Echinococcus granulosus was found in 2.3 percent of Ladakh dogs and Taenia hydatigena in 30.3 percent.

Five household habits that cut the risk

• Remove faeces daily, TroCCAP's first environmental rule, because eggs need days in soil to become infective and the coat carries fresh Echinococcus eggs at once.
• Wash hands after every dose and after handling the dog, the Kiwof leaflet's user-safety line.
• Keep the dog off raw meat, offal and carcasses, or heat meat for 10 minutes to a core of 65 degrees C or freeze it a week at minus 17 to minus 20 degrees C, ESCCAP's rule, and TroCCAP's "do not feed raw meat or allow dogs to hunt";.
• Treat every dog and cat in the house on the same day, because TroCCAP says "all dogs and where applicable, cats, should be treated at the same time when residing in the same household or kennel".
• Test the faeces every 3 months to confirm the schedule is working, the TroCCAP diagnosis rule.

The responsibility is written into Indian law. Rule 8(1) of the Animal Birth Control Rules, 2023 says "in case of pet animals, the owner of the animal shall be responsible for the deworming, immunisation and sterilisation", and Rule 8(2) that "in case of street animals, the local authority shall be responsible";. The four-city survey's authors drew the household conclusion themselves: "owners of pet animals exposed to these environments must be extra vigilant in ensuring their animals are regularly dewormed";. Who is supposed to deworm the free-ranging dogs on the street outside, and what a resident can do, is on the stray dogs in India guide.

Signs a dog needs deworming, and what a faecal test costs in India

The signs a dog needs deworming are, in TroCCAP's wording, diarrhoea "often bloody", anaemia, hypoproteinaemia and death in hookworm-infected puppies as young as 10 days, and pot belly, ill thrift, stunting and vomited worms in roundworm-infected pups, while adult dogs and Echinococcus carriers usually show nothing. That is why the guideline asks for a faecal test at least once every 3 months rather than waiting for a sign, and a government veterinary hospital in Bihar charges Rs 100 for it Bihar Animal Sciences University, Patna.

• In puppies: bloody diarrhoea, pale gums from anaemia, low protein and swelling, and sudden death in hookworm disease; in roundworm disease "ill thrift, stunting, abdominal discomfort (pups adopt a straddle-legged posture and a pot-bellied appearance), anorexia, diarrhoea and vomiting (adult worms may be expelled)", and pneumonia or acute death in heavy transplacental infections.
• In adult dogs: "non-regenerative iron deficiency anaemia" from hookworm; large bowel diarrhoea with mucus and fresh blood, weight loss and anaemia from heavy whipworm burdens, though the 411-dog Indian survey found no Trichuris vulpis at all, "in support of previous canine surveys in India"; and scooting, with tapeworm segments in the faeces, coat, bedding or around the anus, from Dipylidium after fleas, the segments "shaped like rice grains" when dry Traub RJ, Pednekar RP, Cuttell L ESCCAP Guideline 01.
• No sign at all: the Echinococcus carrier, in TroCCAP's words "dogs are unlikely to show clinical signs of infection", and the adult dog with arrested Toxocara larvae in its tissues.

The faecal test is a flotation. TroCCAP recommends "standard or modified faecal flotation using a solution with specific gravity (S.G.) generally between 1.18 to 1.25", warns that "clinical signs might occur prior to shedding of parasite stages in the faeces", and, because shedding is intermittent, says "testing three or more samples, on alternate days, may increase the probability of finding diagnostic stages". Two limits matter when reading a negative result: an adult with no Toxocara eggs may still carry arrested larvae, and Echinococcus eggs "are rarely shed in faeces" and "are morphologically indistinguishable from eggs of Taenia spp.", so diagnosis "should be based on the animal's history i.e. access to raw offal";. ESCCAP adds that faecal tests for tapeworm are unreliable, which is why it treats against tapeworms at least 4 times a year whatever the test says.

What a faecal test costs in India

What it costs in India, from a government hospital's own rate card: the Veterinary Clinical Complex of Bihar Animal Sciences University, Patna, lists "Faecal Examination (Dog, Cat & Wild Animals)" at Rs 100, against Rs 25 for cattle, horses and goats, with canine registration at Rs 200 for the morning OPD (valid 10 days) or Rs 300 for the afternoon emergency window, a blood parasite examination at Rs 100 and a heartworm test at Rs 300. Rs 100 divided by 84.38 is 1.19 and by 74 is 1.35: a rupee-native round fee, not a conversion. A private veterinary diagnostic chain with Delhi centres lists "Stool Examination Routine" only inside wellness packages, so no standalone private figure was obtainable. Ask for the flotation on the same visit as the dose; TroCCAP suggests exactly that pairing, "during routine consultations (e.g. vaccinations)";.

Eight deworming mistakes Indian owners make, each contradicted by a leaflet or guideline

Eight deworming mistakes recur in Indian homes, and each one is contradicted by a source quoted on this page: worming once or twice a year, dosing by guess, stacking two products, skipping the mother, treating one dog in a multi-pet house, feeding offal, sweeping up the post-dose faeces, and giving livestock ivermectin to a herding breed. They are listed below with the sentence that rules each one out.

1. Deworming once or twice a year. ESCCAP: "Studies have shown that 1-3 annual dewormings do not provide sufficient protection", and the floor when risk is unclear is 4 times a year. TroCCAP says monthly.
2. Dosing by breed, age or guess. Every dose on this page is per kg of body weight, and the Kiwof bands step every 5 kg Tropical Council for Companion Animal…. Weigh the dog.
3. Stacking two dewormers, or a dewormer on top of a monthly combination chew. "Should be used alone and never combined with other deworming medicine"; "do not use simultaneously with piperazine compounds".
4. Leaving the mother out. "Treat the dam at the same time" as the 2-week puppy dose; ESCCAP times the lactating bitch to the same day.
5. Treating the dog that scoots and not the others. "All dogs and where applicable, cats, should be treated at the same time when residing in the same household or kennel".
6. Feeding raw offal, or letting the dog scavenge near a slaughter point. TroCCAP names northern India as Echinococcus-endemic and says owners "should be strongly encouraged to limit the access of their dog to offal"; ESCCAP's rule is monthly praziquantel for a dog at high risk.
7. Sweeping the post-dose faeces into the drain. Burn, bury deep, or flush for 48 hours after praziquantel; the leaflet adds bleach at 3.75 percent or stronger.
8. Giving injectable or livestock ivermectin to a collie, sheltie, Australian Shepherd or German Shepherd without an MDR1 test. TroCCAP's explicit caution, and WSU's 70 percent Collie frequency Washington State University.

None of this replaces the person who can weigh the dog, read the slide and knows the local worm pressure. TroCCAP puts every off-label decision on "the veterinary practitioner in charge";, ESCCAP opens its scheme with "deworming practices should always be on the advice of a veterinary professional";, and the Indian leaflet is labelled "for the use of Registered Veterinary Practitioner, Hospital or Laboratory";. Use the intervals here to ask a better question; your nearby vet decides the schedule and the dose for your dog. The shots dated against the doses are on the dog vaccination schedule in India guide, and the cat version of this page is the cat deworming schedule for India.
