We got my puppy about 2 months ago and he had had runny poop. He didnt have it when they gave us the dog. We changed his food and gave him new treats cu's the food they where giving him was cheep food so we got better food and at first we thought is was the treats so we stoped giving him those and got new treats and it still has not stoped he did get yelled at a few time for going in the house and I'm wondering if it might be stress or the food. He is a puppy so we also thing he is teething. He is going on his last shots in 2weeks. He started them late. Please help me I don't know what I could do for my puppy.
