First, dried tomato pomace. Some people consider this as well as pea fibers a filler ingredient.

Pea protein is next. Pea protein is about 80% protein which bumps up the overall protein content of the product but this is only one of the ingredients that provides protein.

Alfalfa nutrient concentrate is also about 50% protein. And then of course there is the meat included in the recipe.

Dried yeast, some dogs are allergic to this so be cautious if your dog is.

One other thing to note is that flaxseeds are the source of omega-6 and omega-3 fatty acids. 

Ingredients for Merrick Classic Beef, Peas with Ancient Grains:

Deboned Beef, Pork Meal, Peas, Brown Rice, Barley, Pork Fat (preserved with mixed tocopherols), Lamb Meal, Natural Flavor, Pea Protein, Oatmeal, Quinoa, Beef Liver, Salmon Meal, Carrots, Apples, Flaxseed Oil (source of Omega-3 fatty acids), Blueberries, Chia Seed, Organic Dried Alfalfa Meal, Salt, Choline Chloride, Minerals (Iron Amino Acid Complex, Zinc Amino Acid Complex, Zinc Sulfate, Sodium Selenite, Manganese Amino Acid Complex, Copper Amino Acid Complex, Potassium Iodide, Cobalt Proteinate, Cobalt Carbonate), Yucca Schidigera Extract, Vitamins (Vitamin E Supplement, Vitamin B12 Supplement, Vitamin A Acetate, d-Calcium Pantothenate, Thiamine Mononitrate, Niacin, Riboflavin Supplement, Biotin, Vitamin D3 Supplement, Folic Acid, Pyridoxine Hydrochloride), Dried Lactobacillus plantarum Fermentation Product, Dried Lactobacillus casei Fermentation Product, Dried Enterococcus faecium Fermentation Product, Dried Lactobacillus acidophilus Fermentation Product.

We have discussed many of these already with the Blue Buffalo ingredient list but let’s touch quickly on a few.

Pea protein is about 80% protein, which is good for the overall protein but more is required, therefor, that is why more ingredients with protein are included.

Flax oil is the source of omega fatty acids. 

Organic dried alfalfa meal is the next ingredient of interest. This is typically thought of as more of a horse feed. However, I would argue that a grass like alfalfa is a more normal ingredient for a dog to eat then grains are.

Next, we have 4 probiotic sources which are great for your dog.

One more thing to take note of, both foods have added vitamin B12.
