Pet's info: Dog | Labrador Retriever | Male

I bought my dog Rachel Ray grain free salmon dry food, unfortunately he was allergic to it. I also bought him nature's recipe salmon grain free dry food and he is always thirsty. I don't know what else to buy him. Which food do you reccomend?

Hi there. I normally recommend feeding a food like Royal Canin, Iams, or Purina. These companies have a great deal of research behind their diets to prove that they are complete and balanced, and provide appropriate nutrition for whatever age or life stage the food is labeled for - puppies, adult dogs, seniors, etc. There is no particular benefit to feeding a grain-free diet unless your dog happens to be allergic to some type of grain, which isn't very common - most food allergies in dogs are to proteins such as chicken, beef, etc. If you think that Gary has food allergies, you may want to talk to your veterinarian about doing a diet trial with a prescription hypoallergenic diet such as Purina HA or Hills z/d.
