Food & NutritionWhen is it safe to switch my puppy from Diamond to Blue Wilderness?
Trusty is a good looking pup! I don’t recommend to feed grain free diets unless you know that your dog has a grain allergy. Just so you know, food allergies are uncommon and represent less than 10% of all dogs who have allergies. When pets do you have food allergies, it is usually to the protein, not grains or other carbohydrate sources. Well the connection is not clear yet, there does appear to be a link between grain free diet and heart disease. This likely involves a genetic predisposition to heart disease that the diet exacerbates. I recommend to stay on the diamond food between the two but there are diets I think are better. Royal Canin, Nutro and Purina Pro Plan all produce very high-quality diets that are highly digestible and formulated correctly. Your puppy does need to be eating a large breed puppy food to help avoid skeletal issues as an adult. I hope this helps and please feel free to post any additional questions.
