The food i would Suggest eliminates Chicken, Potato and ANY grain altogether.. its called Canine Caviar. it has venison, duck, or herring available for the grain free diets. its very similar to a raw diet but in kibble form (dehydrated raw pretty much).
this food has prebiotics and probiotics in the food so its Fantastic for allergy prone dogs, it also has Kelp which is good for fighting off any pollutants as well.
I would HIGHLY recommend this food since you would not have to add any supplements to the food at all. look the food up, its extremely limited in the ingredients and you will understand what each ingredient is which is always a benefit.
this food will help with dogs who throw up a lot, i work in a global pet foods in Ontario and ive seen this food do fantastic things for dogs with the exact same symptoms. i hope this helps.
