Not unusual I have cooked for all my dogs over the years, sweet potato, vegetables, brown rice, with meat (all except pork), was advised to use one type of meat at a time not to mix meats, plated up with handful of kibble (don't trust all brands) twice a day.
Do love the feeding stand, taller dogs need this.
That was Pura's idea. Hers are always the good ones.
She loves sweet potato. Brown rice, oh Joan. Just recently, not even two weeks ago, we learned she can't do brown rice. White, yes. Brown.... omg.. Poor thing. Took like 5 days to figure it out.
Making wrong choice does happen, some of my dogs loved samp (maize) till one had problems with dry skin which I immediately stopped after a week or two feeding.
My sister had a beautiful dog like Pura, found the floor polish she used in the home the dog was allergic to. Dogs like humans definitely encounter problems from different things.
