Thanks for the reply I really appreciate it. He’s 8 weeks old. The breeder told me he was dewormed but when I asked her about it this morning she stopped answering so I’m starting to wonder. Do you recommend I keep the stool from right now till Tuesday? Or would bringing a sample that morning be better? Thanks again Much appreciatedHow old is the dog? Worms in a baby puppy stool is more critical than in an older dog. Be sure to bring a stool sample to your vet including some of the worms if you can so they can diagnose the type of worm and give you the correct worming medication.
