Usualy this is one dose based on the dog's weight and then repeat in 2-3 weeks if you are trying to clear hook or round worms. If the dog has no more fleas (they carry the tapeworms) you should not need to repeat to clear tapeworms. The container should have directions on it.
This product is good for hookworms, roundworms, and tapeworms only and will not clear whipworms.
Hope this helps you!
