Puppy Deworming Schedule: How Many Treatments Are Needed?

Most veterinary guidelines recommend that puppies receive deworming treatments every 2 weeks starting at 2 weeks of age and continuing until they are 12 weeks old. After that, monthly treatments are given until the puppy is 6 months old. This adds up to roughly 6 to 8 treatments in total, though the exact number can vary based on your puppy’s risk factors and the specific dewormer used.

AgeFrequencyTypical Number of Treatments
2–8 weeksEvery 2 weeks4 treatments
8–12 weeksEvery 2 weeks2–3 treatments
12 weeks–6 monthsMonthly3–4 treatments
Total—6–8 treatments

This schedule aligns with the American Veterinary Medical Association’s guidance on parasite control. Puppies are especially vulnerable to roundworms and hookworms, which they can get from their mother before birth or through nursing. Regular deworming is essential to prevent growth delays, anemia, and other health issues.

At The Pet Hospital of La Mesa, we tailor the deworming schedule to your puppy’s lifestyle. For example, if your puppy goes to daycare or spends time in areas with high parasite exposure, we may recommend more frequent treatments. We also perform fecal tests to identify the exact parasites and adjust the plan accordingly.

Timing Your Puppy’s Deworming: A Week-by-Week Guide

Timing is critical because puppies are most susceptible to parasites during their first few months. Here’s a typical week-by-week guide to when each deworming dose should be given.

AgeDeworming DoseNotes
2 weeksFirst doseUsually given by the breeder or rescue; if not, start immediately.
4 weeksSecond doseContinues to target roundworms and hookworms.
6 weeksThird doseOften coincides with first vaccinations.
8 weeksFourth doseCommon time for first vet visit; fecal test may be done.
10 weeksFifth doseDepending on the product and risk.
12 weeksSixth doseTransition to monthly schedule.
4–6 monthsMonthly dosesContinue until 6 months of age.

It’s important to keep a record of each deworming treatment. Your vet can provide a schedule and reminders. In La Mesa, many new puppy owners bring their pups to us right after adoption, and we help them set up the entire series.

If you miss a dose, don’t panic—just call us and we’ll reschedule. Consistency is key to breaking the parasite life cycle.

Frequently asked questions

Can I deworm my puppy at home without a vet?

It’s not recommended. Over-the-counter dewormers may not cover all parasites, and you might miss the correct dosage. A vet can identify the specific worms and prescribe the right treatment.

What are the signs that my puppy has worms?

Common signs include a pot-bellied appearance, diarrhea, vomiting, weight loss, and visible worms in the stool. However, some puppies show no signs, which is why regular deworming is important.

Do I need to deworm my puppy if it’s indoors only?

Yes. Puppies can get worms from their mother before birth or through nursing. Even indoor puppies are at risk, so follow the recommended schedule.

How often should adult dogs be dewormed?

Adult dogs typically need deworming once every 3 to 6 months, depending on their lifestyle and risk of exposure. Your vet can recommend a schedule based on your dog’s needs.
