My puppy is 9 weeks old and came home last Thursday. From the off he has had very runny poo. He isn’t pooing excessively (about 3 times a day) but when he does it is water. Spoke to the vet who said it could be stress from coming home and to try chicken and rice for 3 days. He has now been on chicken and rice for 24 hours and is having solid poo. My question is what food do I put him on after day 3 of chicken and rice. Should I continue with the food the breeder sent with him or should I try him on something new. If so, what??? Any good puppy foods for sensitive stomachs? He was on wet food. Would dry be better?
