I at the advice of 3 different vets and 2 different trainers NEVER gave my CC pup ..puppy food I give him evo red small bites (beef) mixed with evo yellow (Chicken) small bites with some pumpkin, at least 1 x amonth I give him sardines in olive oil 1/2 can a day 1/2 can 4 days later.. I also give raw marrow beef bones 2 x a month Rocco is now 6 mos and 10 days old and weighs 73.7 lbs (both parents over 130)as they told me it promotes to fast a growth rate in large breeds..he also gets flax seed oil and a bit of bone meal every 3rd day with a bit of Glucosamine 500mg every day.
