I've never heard of eye staining from too high protein of diet? That's new to me.
I know a lot of dogs get eye boogers on crappy foods, like Ol' Roy, Purina, Kibbles n Bits, and foods with lots of fillers. But sometimes different ingredients react to different dogs in different ways... I think it's just a matter of finding what works right for your dog. Fromm is an excellent food, IMO, but it causes major eye boogers in Jackson as well as a few others here on YT. |
