Deworming schedule for dogs and cats in India: how often, which worms, and what it costs

Deworming is the cheapest routine care your pet gets and the one most people forget. India's warm, humid climate keeps intestinal parasites active year-round, and several of them pass to humans. Here is the schedule, the signs you are overdue, and why the price makes skipping it pointless.

Why India is different

Most deworming schedules online come from countries with cold winters, where parasite transmission drops for months at a time. India does not have that pause. Warm, humid conditions keep worm eggs viable in soil year-round, and the routes of infection are everywhere: contaminated soil, puddles, fleas, the mother's milk, and contact with other dogs, of which most Indian neighbourhoods have plenty.

That is why Indian vets recommend more frequent deworming than international guidelines, and why a schedule copied from a US site will leave your pet under-protected.

The other reason it matters more here is the people. Roundworm and hookworm pass readily to humans, and children who play on the floor are the most exposed. Deworming the pet is household hygiene, not just pet care.

The schedule by age

The intensive early schedule exists because puppies and kittens are often born with roundworm passed from the mother, and can carry a heavy load by a few weeks old. Two-weekly dosing until twelve weeks clears the initial infection and the reinfections that follow.

The worms you are actually treating

Not every dewormer covers every worm. A basic tablet usually handles roundworm and hookworm. Tapeworm needs a product that includes praziquantel. Ask your vet for a broad-spectrum product, or make sure you know what yours covers. Heartworm is a separate conversation entirely and is worth having if you live somewhere with heavy mosquitoes.

Signs you have left it too long

• Pot belly on a puppy or kitten that is otherwise thin
• Dull coat and poor weight gain despite eating well
• Visible worms in stool or vomit, or rice-like segments around the tail
• Diarrhoea, sometimes with blood or mucus
• Scooting, dragging the rear along the ground
• Pale gums, which in a puppy can mean hookworm anaemia and needs a vet promptly

A pet showing none of these can still carry worms. The schedule exists precisely because a low-level infection is invisible until it is not.

What it costs

An adult dog on a three-monthly schedule costs a few hundred rupees a year to deworm. Treating an established hookworm anaemia costs many times that. There is no version of the maths where skipping it saves money. Our vet cost guide puts this in the context of everything else.

How to do it properly

1. Weigh the pet. Dewormers are dosed by weight, and guessing means under-dosing, which does not clear the infection, or over-dosing, which is unpleasant for the animal.
2. Get the first product from a vet. After that, most are safe to give at home, but the initial choice of product and dose should be professional, especially for puppies and kittens.
3. Give it with food unless the label says otherwise. It reduces vomiting.
4. Write the date down. The reason most pets are overdue is not cost or difficulty. It is that nobody remembers when the last dose was.
5. Control fleas at the same time. Tapeworm reinfection comes from swallowing fleas, so deworming without flea prevention is half a job.

That last point about dates is the practical one. Deworming fails through forgetting, not through anything complicated. A record you can actually find, which is what Pawspert's health timeline is for, solves the only hard part.
