Deworming Schedule for Puppies in India: Age-Wise Chart and Safe Practice

Deworming means giving a puppy medicine that clears intestinal worms such as roundworms and hookworms. Most puppies pick up worms from their mother before birth or through her milk, so treatment starts early. Veterinary guidelines commonly recommend the first deworming at around 2 weeks of age, repeated every 2 weeks in early puppyhood, then monthly until about 6 months. Your vet should confirm the exact schedule and product, based on your puppy’s weight, health and surroundings.

If you are bringing home a puppy at 8 weeks or later, it should already have had several doses. This guide explains the usual schedule, the signs to watch for and how to check a puppy’s deworming record before you buy.

Why Is Deworming Important for Puppies?

Puppies are especially vulnerable to intestinal parasites. The most common ones are:

• Roundworms: the most common worms in puppies, often passed from the mother
• Hookworms: small worms that feed on blood in the intestine and can cause anaemia in young puppies
• Whipworms and tapeworms: usually picked up later from the environment or, for some tapeworms, from fleas

Worms take nutrients that a growing puppy needs. Heavy infections can slow growth, upset digestion, reduce appetite and, in very young puppies, become life-threatening.

Puppies get worms in two main ways. They can be infected by their mother before birth or while nursing, and they can pick up worm eggs from contaminated soil, faeces or surfaces once they start exploring.

This is why deworming is preventive care. A puppy can carry worms and still look healthy, so treatment follows a schedule rather than waiting for symptoms.

Puppy Deworming Schedule in India: Age-Wise Chart

The chart below reflects commonly recommended veterinary practice. It is a general guide, not a prescription. Your vet may shorten or extend it based on your puppy’s weight, health and parasite risk.

Why every 2 weeks at first? Worms acquired from the mother mature in waves. Repeating treatment every two weeks clears each new wave before it can start laying eggs.

Never estimate a dose or reuse leftover medicine from another dog. The correct product and dose depend on your puppy’s exact weight and age.

Deworming Before or After Vaccination?

Deworming and vaccination do different jobs, and a puppy needs both. Deworming does not replace vaccination, and vaccination does not protect against worms.

In practice, many vets deworm puppies around the time of their vaccinations. A heavy worm burden can leave a puppy weak, so clearing worms supports overall health. The vet should decide the order and gap between the two, because it depends on the puppy’s condition on that day. For the vaccine timeline, see our puppy vaccination schedule in India.

If your puppy has diarrhoea, vomiting, weakness or refuses food, contact your vet before giving any treatment. Do not delay, skip or give a deworming or vaccine dose on your own based on online advice.

Signs Your Puppy May Have Worms

Some puppies show clear signs, while others show none at all. Possible signs include:

Symptoms alone cannot tell which parasite is involved, and a clean-looking stool does not rule out worms. Your vet may suggest a stool examination to confirm the type of worm and choose the right treatment.

External parasites like ticks and fleas need separate prevention. Some tapeworms spread through fleas, so the two are linked. Read our guide on tick and flea prevention for dogs in India.

How to Deworm a Puppy Safely

• Weigh your puppy accurately before every dose. Puppies grow fast, and an old weight gives the wrong dose.
• Use only a vet-recommended product that is suitable for your puppy’s age and weight.
• Never use human deworming medicine, and never guess the dose.
• Clean up faeces promptly and wash your hands afterwards. Some dog worms can also infect people, especially children.
• Ask your vet whether a stool test or a repeat dose is needed.
• Keep a written record of the product, date, prescribed dose and next due date.

For daily care beyond deworming, our puppy health and care guide covers feeding, hygiene and first-week routines.

Deworming Records to Check When Buying a Puppy

Most puppies go to new homes at 8 weeks or older, by which time several doses should be done. Before you pay, ask the breeder or seller for:

• Dates of every deworming dose given so far
• The product used, as recorded by the vet
• The puppy’s current weight and general health record
• Vaccination records and the date of the next vet visit
• Whether a vet has examined the puppy for signs of illness

Ask to see the written record rather than accepting a verbal assurance. If no record exists, tell your vet, who will usually restart the early schedule to be safe. 

Deworming records and KCI registration are different things. KCI papers record a puppy’s pedigree, while deworming and vaccination records show its health care. Our KCI certification guide explains what KCI papers do and do not prove. Neither replaces a vet’s health check. If you are buying through GoodFurs, see how to buy a puppy, and ask for the deworming record along with the vaccination card.

What Happens After the Puppy Reaches Adulthood?

Around 6 months, your puppy moves to an adult parasite prevention plan. There is no single interval that suits every dog. Your vet will decide based on:

• Lifestyle: time outdoors, parks, contact with other dogs
• Local risk: hygiene in the area, stray animal contact
• Household: young children or people with weak immunity at home
• The product used: some preventives cover several parasites at once

Some dogs are treated monthly and others every few months, often alongside routine stool checks. Follow your vet’s plan rather than a fixed online schedule.

Conclusion

A good deworming schedule for puppies starts early, repeats often in the first months, and then moves to a vet-guided adult plan. Accurate dosing by weight, clean surroundings and a written record of every treatment matter as much as the medicine itself. If you are buying a puppy, check its deworming and vaccination records before you bring it home, and book a vet visit in the first week.
