First off i'm sorry for how crude this sounds.But my min pin has these flat worms that come out off his butt. I've tried D-Worm acouple times but it hasn't helped. I'm not sure what kind of wroms these are. I always thought the worms come out in the stool. But his don't and there still alive. Is there any other kind of stuff I can use. He hates going to the vets and the vet don't like him either. Thanks for any help.
