Yes if your dog has skin allergies or other allergies and is allergic to most other brands of dog foods then Pure Balance Dog food would likely be perfect for your dog with allergies.
I have a dog that has skin allergies and breaks out in rashes when eating other brands of dog food but since I switched him to Pure Balance Dog food he doesn't break out with any skin rashes or suffer from any other allergies when eating Pure Balance Dog Food.
Pure balance dog food is a more natural plant based dog food so it's also much healthier for your dog than other dog foods available.
My dog seems to love the pure balance dog food much better and eats it better than any other dog food I bought for him.
Your dog should not suffer from any other allergies if you switch him to pure balance dog food but if he does then the dog could be allergic to that dog food as well.
All dogs just like people can be allergic to different things but pure balance dog food is good for dogs with allergies.
