I have a 16 month old pitX. we have had him since he was 6 months old and the people we got him from never did any kind of training with him so we have been working really hard the last 10 months to get him under control. He was doing great and now he has started jumping up and knocking the kids over. He jumps up on my oldest son and always ends up knocking him down and licking him like crazy. I know he's trying to play and he would never hurt them, I just can't seem to get him to stop. Do yall have any advice to help him stop jumping up on them?
