Great food

I've fed Diamond Naturals lamb and rice large breed for a few years. Switching all my dogs to this. I have one that is sensitive to different foods and he's doing great on this. Less to clean up in the yard too.

Great Ingredients, poor palatability

3 years ago

On paper, this looked like an amazing high caloric feed for my dog that has chicken allergies. The ingredients list is high quality; however, the palatability of this product is poor. I had hoped after feeding out two bags that my dog would grow to appreciate the flavor - this did not happen. I would not consider this dog a "picky eater". I wish Diamond had a similar high calorie fish/lamb-based product.

So far so good!! Our big guy turned a year in January and had been on puppy food. I had researched a good brand and we landed on this one. He seems to really like it and we have had no digestive issues.
