Bobby is 14 months. It seems that his behavior around other doggies lately has changed. It doesnt matter if they are girls or boys, he tries to mount them. And he wont stop. Since we waited so long to get neutered I am wondering if this will stop after his surgery on the 5th? Last night we brought him to meet a new little boy puppy. I was hoping this could be his little brother. But all he did was try to mount him and scared the puppy. The little guy did stick up for himself, but I wouldnt feel comfortable bringing him home if this is how Bobby is acting. Its to the point now, that I am worried to bring him around other doggies because of this behavior. He is fine at home, doesn't show any aggression or humping behavior. (it's just me and my husband) Just around other dogs. Have any of you gone through this with your little boys?
