What is the suggested basic deworming protocol?
The most practical dewormer to use for treatment of roundworms and hookworms is pyrantel (Strongid® or Nemex®). Puppies and kittens should be treated immediately on intake (as early as 2 weeks of age), and again every 2-3 weeks until 8-12 weeks of age. Re-treatment is very important! For deworming of adults, two doses of pyrantel are recommended: one immediately on intake, another 3 weeks later if still in the shelter. If whipworms, tapeworms, Giardia, or coccidia are diagnosed, or other parasites are a common problem, the protocol can be changed as needed. What about environmental contamination? The eggs or cysts of some parasites are very resistant to disinfection and will persist in the environment for a very long time. Examples of these are roundworms and coccidian. Other parasites, such as Giardia and Tritrichomonas, are quite fragile in the environment and easily destroyed by most disinfectants as well as by drying.
