I am considering transitioning my puppy from hills science to merrick grain free dry dog food. Is merrick a good brand? What are the benefits of grain free dry dog food? What are the differences in feeding a dog salmon Vs chicken vs lamb vs duck?

Thank you for submitting your question regarding Korbyn. These are all great questions! There are few dogs that are actually allergic to grains. The ones that are tend to be Irish Setters. Grain free diets have developed mainly as a marketing ploy to add a niche market in the pet food department. Now if your individual dog does better on a grain free diet that is great and fine to feed it to him. However, these diets tend to be higher in carbohydrates and will lead to weight gain. Protein source typically a personal preference of the dog. You can see what he likes and how it agrees with him. You need to determine what your goals are for the new diet. Is your puppy experiencing vomiting and diarrhea on his current food? Is he passing large frequent quantities of stool? Does he have a dry brittle hair coat? These are all signs that his diet is not right for him. When transitioning to a new diet, you want to do it gradually and then see if any of these things improve for him. As far as a brand, I recommend using one that has AAFCO certified. You can find this information on the side of the bag or on the company website. This means the diet has undergone testing and proved efficacious. I hope this information helps!
