All three brands are excellent choices. A bit high on protein for my taste. Keep in mind that a lot of dogs can't handle the high protein foods. Maddie definitely needs grains in her food otherwise she has loose stool issues. I have tried the Innova Evo and the Blue with her and she did have loose stools with both foods. The trick is finding a food that your dogs will thrive on and one that they enjoy. Good luck in your food search!
Whole Dog Journal gives high marks to the EVO and the Champion Pet food which are both also grain-free I would choose one of those if it was for my dogs, it is the closest to a natural diet for dogs. Grain free is a good choice for dogs with allergies and dogs really don't need nor digest grains well. You need to carefully measure portions as this is a nutrient dense food.
Blue Buffalo had some issues with recalls and they won't disclose some of their sources or where it is made so WDJ doesn't recommend them anymore.
I agree with Tootsie that they are all great quality foods but they are too high in protein for me as well. Every dog is different and will respond differently to each food. Maybe trying to get some samples of these foods first might help, especially where you have three dogs. Probably easier that way to find one that agrees with all of them before dropping the money on these foods.
If your pups are under the age of 18 months I would definitely not feed anything with a protein content higher than 28%. You don't want to encourage faster growth with the added protein levels, especially since boxers are fast growers to begin with. That can lead to joint and skeletal issues later in life.
I was wondering why a food would contain such high protien when my puppy food ( I am feeding her IAM's because she refused Science diet, and Purina Pro-plan..don't know why :roll: ) had 28%, then I switched her to large breed and it had 26%. Great anwser to a constant question I have.
Also, I have been trying to keep her fibers to 3% or less because she become's a poo factory if its higher and I always wondered if food moving through a digestive tract at that pace even gave your dog any nutrients.
There have been so many studies on this that show there may be a link with bone problems and the amount of protein in food. Boxers are technically a medium sized breed, however the dog food manufacturers formulate their large breed foods for any dog over 50 pounds. Large breed foods were formulated to encourage slower and more even growth by controlling the amount of fat and protein in their foods. Boxers are fast growing pups, and with fast growth we see more skeletal problems such as hip, knee dysplasia, and HOD, which large breed dogs are more prone to. Granted Great Dane's and the giant breeds are more prone to acquiring these joint issues, but boxers are still a fast growing pup.
Puppy formulas tend to have more protein in them which can promote faster growth in puppies leading to some of these skeletal and joint problems later on. They are formulating the large breed puppy foods with less protein and fat to try and slow down the growth. The difference in some puppy formulas vs. large breed formulas are so slim, I think it's more of a sales gimmick. I just tend to want to stay 28% or less protein, whatever the formula.
I personally still believe that large breed puppy bone problems are primarily genetic and inherited, but given the choices of food available today, I would opt for the best and healthiest choice that I can find. At the very least, it is excellent nutrition and if it does help with the skeletal issues, I would consider that a big + !
