We tried Horizon Legacy a while back. Pippa seemed to be allergic to it and scratched her muzzle, neck, ears, etc. incessantly after eating and ended up with hotspots. However, Dallas our Whippet did quite well on it. It's one of the foods that agreed with his very gassy stomach. I think it's a really good food and I like the company behind it, it just didn't agree with Pippa for some reason.
