Is feeding a 5month old pitbull blue buffalo wilderness good or bad for him?

I have been feeding my 5 month old pit bull blue buffalo puppy... he eats 1 cup every meal... mixed blue buffalo wilderness with blue buffalo puppy and he ate 1 1/2 cups... should i not feed himn wilderness or stay with puppy?Is feeding a 5month old pitbull blue buffalo wilderness good or bad for him?
That should be fine, i use blue buffalo wilderness since my pup was 2 month old!Is feeding a 5month old pitbull blue buffalo wilderness good or bad for him?
I would stay with puppy until at least 6 months. Puppy food has minerals and vitamins that are essential to a puppy's growth. Mixing with the puppy food is excellent, so once he does get to 6 months you can switch him strictly to wilderness. Thats what i did to my wiemaraner.
