What is the suggested protocol for prophylactic roundworm and hookworm treatment in dogs and cats?
The most practical dewormer to use for treatment of roundworms and hookworms is pyrantel (Strongid® or Nemex®). Because subclinical infection is so common, and because animals can be infected very early in life (via intrauterine or transmammary transmission), this is one case where treatment should be administed to all animals rather than based on symptoms or test results. All dogs and cats should be treated immediately on intake (puppies and kittens starting as early as 2 weeks of age), and again every 2 weeks until 12 weeks of age. Re-treatment is very important! Because of the life cycle of these parasites, it is not possible to eliminate infection with a single treatment.
For deworming of adults, two doses of pyrantel are recommended: one immediately on intake, another 2 weeks later if still in the shelter.
