Hello everyone!

I have a 6 month old pup that i rescued just over a month ago. I have tried 3 different hard foods and one soft food. (nutro, pedigree hard, pedigree soft, and purina one) giving each one a week to work. My pup has had nothing but soft stool, sometimes downright runny . I have even tried home cooking with chicken and rice with no such luck. Lately i have been mixing a lamb and rice hard food with chicken and rice (home cooked) and have had medium stool results at best, but still not where i feel it should be.

I have read that these guys have a bit of a sensitive stomach, but i'm not sure what else to try....

Any suggestions?
