Hi Michelle,
No proof just my opinion that breed specific food is just a sales pitch. All dogs are different in a specific breed. Blue Buffalo has had it’s share of problems; I wouldn’t feed it. If you do a google search for Dr. Karen Beckers video on the best food, you’ll see that she feels a high quality wet food (canned, raw, dehydrated) is better than dry. Dry food is dehydrating to dogs (according to her). If you must feed dry, at least add warm water to it and/or canned.
I doubt one grape will cause any kidney problems. Don’t bother talking dog food with your vet unless it’s a holistic vet or nutritionist. They get very little nutrition education in vet school.
Why do you think she has a skin allergy? Pick a food and stick with it. If you keep changing foods because you think she doesn’t like it, you’re going to create a picky eater. Switching foods often is a great thing to do but leave her on one food for a bag, or more, then transition to something else.
