I just got a miniature Pinscher, he is about 7 weeks old. He had worms, we took him to the vet to be treated. 2 days ago he was dewormed. I'm noticing that his stool is bright orange, with a mucus jelly like texture to it. He is still playful, but is eating less since yesterday. I can still get him to eat though but he seems to be less eager about it. Should I be worried? Could this be parvo?
