There are numerous dewormers on the market and they are readily available in various locations from your local veterinary clinic to local hardware store. All present dewormers are orally administered and come in liquid, paste or gel form. There are four drug categories that help to eliminate roundworms and two that help to eliminate tapeworms.
These categories can vary in their efficacy in eliminating the various parasites, the various stages of the parasite they control and the duration of control they offer. Often these product categories have several products within their group so it soon becomes very confusing and is difficult to make a decision of what product to purchase. A proper, scientific choice is best made in consultation with your veterinarian.
