I was wondering if anyone else is feeding Taste of the Wild - high prairie dry and is experiencing staining around the dogs mouth?
I know it has "beet pulp" in it and that is known for staining. I also mix in some Merrick canned food and he likes to drink water after eating. He also likes to lick his chops when he is done. So his mouth is almost always wet after eating.
Yes, don't worry about the protein. Even while my chihuahua was being diagnosed with kidney problems, my vet said it was not caused from TOTW or higher protein content. My vet did recommended that I reduce his protein intake now, he said it did not cause the problem. BAD FOOD caused the problem (think china recall).
Good luck!
