I have used Diamond Naturals dog food for years with large breed adults and puppies but it had been a while since I had a puppy. Saw reviews mentioning persistent loose stool after switching to this food, but was hopeful we might be able to manage our puppy through if that came up. Unfortunately our puppy also had very loose and frequent stool regardless of how slowly we transitioned from old food. Wish this could have worked out.

Not good!

Got this food as we feed my other dog Diamond naturals skin and coat formula. Day 1 my puppy was fine, day 2 started with horrible diarrhea, by day 3 it was almost water he was pooping and every 2 minutes. Immediately switched him and resolved within 12 hours. Will not be getting this again sadly because the adult food does well for my household!

The breeder who sold me my Great Pyrenees puppy, recommended Diamond Naturals Large Breed Puppy dry food, and I’ve used it since I brought Floki home as a 15-week old puppy. He’s happy, active, and at a healthy weight at 16 months.
