One of the puppies had an accident yesterday afternoon but seemed fine afterwards and so we put it down to maybe nerves because my sister and her family were here and the kids were really rowdy. This morning early he couldn't hold it and had some more runny stool in his crate. And just now we heard a noise, looked over and it's all over the crate, outside the crate and in the food bowl. I haven't changed their diet. I'm waiting to hear back from a vet. Any ideas?
