My Golden is a little over a year old. My question his weight has remained the same at about 72lbs for the last 2 months. He has not been neutered, eats 4+ cups of grain free food per day. He does get a decent amount of running exercise per day. His dad was 90lbs and mom was 80lbs. Is this normal for a golden? I Know that they dont fully mature till 18 months. I just wanted to know if this seems normal to most of you.
