Strategic deworming is a practice recommended by the American Association of Veterinary Parasitologists (AAVP) and the Centers for Disease Control and Prevention (CDC).

Puppies*

Initiate treatments at 2 weeks, repeat at 4, 6, and 8 weeks of age. Thereafter use a heartworm preventative medication that is also effective against hookworms and roundworms.

Kittens*

In kittens, because prenatal infection does not occur, egg excretion begins later than in puppies, and in most areas, the risk of roundworms and hookworms in cats is comparatively lower; deworming for kittens can be started effectively at 6 weeks of age and be repeated at 8 and 10 weeks.

Nursing Dams

Treat concurrently with pups or kittens.

Adult Dogs and Cats

Treat regularly for prevention. Also monitor and eliminate parasites in pet's environment.

Newly Acquired Animals

Worm immediately, after 2 weeks, and then follow above recommendations.

* Drs. Foster and Smith suggest that owners of newly acquired puppies and kittens should obtain the deworming history of their new pet and contact their veterinarian to determine if additional deworming is needed.
