This is my first puppy (Goldendoodle) He was born in July 2006. Took to vet and tested 3 times for worms. Put on Sentinel in Sept. 2006. Now is passing roundworms in stool. I know sentinel helps with heartworm and fleas but I thought it was to work on other worms as well. Why didn't it prevent this roundworm outbreak?

Sentinel will prevent roundworms. Your puppy is most likely passing tapeworm segments. They look like small grains of white rice, but are actually segments of a larger tapeworm that break off and get passed out in the stool. Dogs get tapeworms from eating fleas. Your vet can give your puppy a quick dose of oral medication that will end the tapeworm problem. As long as you keep your puppy free of fleas, he won't get more tapeworms.
