I had issues with my 9 year old when she was a puppy. She was on Hill's large breed puppy food, and it did not agree with her at all. Turns out she is allergic to corn, which is a common filler in dog food. It got so bad that we had to do a cold turkey switch to Canidae at 15 weeks old. One thing that helped loads with her loose stools with adding a tablespoon of pureed pure pumpkin in with her kibble, and an additional tablespoon of plain greek yogurt. If you have her on Orijin, one of the issues could be the extremely high protein content in the food. I would recommend switching to a food with a lower protein content. I am feeding my 10 week old boy Royal Canin Golden Retriever Puppy, which he is doing really well on. I don't love that it does have corn in it, but it is working and I don't want to mess with that! Dealing with a puppy with diarrhoea is not fun! Hopefully you resolve this issue soon!
