My son found a flat, segmented worm on one of our new dog's poops. It wasn't moving. He also came to use with a little white, crusty looking area on his anus. GROSS! Apparently he has tapeworms. His rescue group said they dewormed him when they rescued him 2 months ago. Could he still be shedding dead worms? Can it sometimes take more than one dose of dewormer for tapeworms?
What do I need to do to make sure it goes away? And that our other dog doesn't get it. And that WE don't get it either!
He's on Heartguard and our other dog is on Interceptor.
