Yeah while you have no eye contact with the puppy because you’re feeding them so much treats, try get them to listen without treats.. please make a video. My 12 week Rottweiler does everything without treats every 3 seconds and gets a treat as a reward. Also it’s not safe to have your puppy running or jumping from so high up it can potentially affect their joints when they get older. Really please make a video without any treats and let me see because if the pup listens. 🙂
Not recommended that larger breed puppies go up or down stairs until they are at least 6 months. The larger the breed, the longer you need to put it off. Irish wolfhound for example, usually wait til it's around 10 months
