Food & NutritionShould I switch my dog and cat from Hill's Science Diet to Wellness?
In my opinion, Wellness is not as good a food as Hill's Science Diet and I agree with the recommendation of your vet's office to keep your dog and cat on Hill's. Hill's has better ingredients and is overall a better quality food. In addition, the truth is that grain free food is really a fad. Only about 5% of dogs have food allergies, and of these dogs, the major of the food allergies are protein. Grain allergies are actually extremely rare, and I only recommend feeding a pet a grain free food if they have a diagnosed grain allergy. I personally recommend keeping your pets on Hill's. I hope this helps!
