Kitten & Puppy Deworming Schedule

Importance of Deworming Puppies and Kittens

Deworming puppies and kittens is crucial for their overall health. Parasites like worms can cause rough coats, diarrhea, malnutrition, intestinal blockages, and anemia. Following a deworming schedule helps prevent these issues before they start.

How to Deworm Puppies and Kittens

Deworming involves giving your pet medicine orally or via injection to kill and prevent internal parasites. Both the American Association of Veterinary Parasitologists (AAVP) and the Centers for Disease Control and Prevention (CDC) recommend strategic deworming.

Deworming Schedule for Puppies and Kittens

Puppies and Kittens:

  • Deworm at 2, 4, 6, and 8 weeks of age.

  • Repeat at 12 and 16 weeks of age.

  • Deworm again at 6 months and 1 year old.

Adult Dogs and Cats:

  • Indoor dogs: Twice a year.

  • Indoor cats: Once a year.

  • Outdoor cats: Four times a year.

Newly Acquired Animals:

  • Deworm immediately, then repeat in two weeks.

  • Follow the adult deworming schedule thereafter.

Managing Deworming Side Effects

Puppies often develop soft stools after deworming. To minimize this, start with a gentle dewormer like pyrantel pamoate at 2, 4, 6, and 8 weeks. This early start can reduce the severity of any digestive upset.

For added protection, deworm the mother during late pregnancy and early lactation using safe products such as fenbendazole. Starting this protocol around day 42 of pregnancy and continuing until the puppies are 14 days old can prevent the transmission of roundworms and hookworms from the mother to the puppies.

Handling Diarrhea After Deworming

If puppies develop diarrhea post-deworming, use a combination of probiotics, fiber, and kaolin-pectin to manage it. Avoid using antibiotics like metronidazole unless necessary, as overuse can lead to antibiotic resistance.

Use veterinary-approved probiotics specific for dogs to ensure effectiveness. Adding fiber from sources like canned pumpkin or high-fiber cereals can also help firm up stools. Kaolin-pectin products can help, but avoid human products containing salicylic acid, which can be harmful to young puppies.

Additional Tips for Deworming

  • Avoid changing food or water sources during deworming and vaccination periods to reduce stress on the puppies.

  • Keep thorough records of all deworming and vaccinations for each pet.
