High protein diets should be kept to those with extremely active dogs as these type of dogs are the only ones that really require it. If you have just a pet or a couch potato theres really no need for such a diet and it can have ample effects later on in life because of it. No offense intended to anyone here, Orijen is an excellent quality food but in all honesty theres no real reason to feed your dog above 34% unless you are working your dog or have a hyper active breed that requires a good bit of exercise every day.
Working your dog is different than having a heavy work load in terms of exercise, which both can benefit from a high protein diet. It can be a similar concept of high protein diets to humans if that makes it more relatable.
Also if you are feeding high protein, obviously as a pup you wouldn't be introducing long or "hard" exercising work loads but in general, as your dog matures and can take more on ideally youd want 2 - 3 + hours every day with various exercising, training, etc IMO if your feeding such a diet.
For instance, with mine 3 hours a day (with the weather being as hot as it is lately) on scheduled times throughout the day and even into the night with the last remaining after the sun sets and it cools off is for various exercises, training and "hard" work outs. Which later this month we are testing for PP and in September start hunting season.. Just to give you an idea as to what i mean by everything, oh and im feeding a 42% protein kibble.
All in all if you can devote at least 2 hours a day, youd probably be alright feeding a high protein diet the biggest thing to keep in mind is to remain active, don't push your dog beyond the limits of course.
Also i would highly recommend you limit the interaction with other dogs, these dogs are not a "dog friendly" breed.. Even if we are talking about a pet bull or American Bully which are "tamer" breeds than the APBT DA (dog aggression) is still a very real possibility. Anything can be a trigger at any time, 2 months to 10 years old theres no "set in stone" method of testing to see if your dog will or wont be DA in the future. If your aiming for socializing i can post the thread i started a while back on the topic which may be useful to you, if your aiming to meet your dogs needs again, these dogs are for you not for everyone else.
