My German Shepherd puppy bites and jumps on walks. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 4 months old

My 4 month old german shepherd puppy keeps jumping up and biting me whenever I take him out on a walk. Inside, he's okay and if he does bite I tell him to stop and he usually listens. This usually only happens on walks whenever I try to correct him he growls and bites harder. If I ignore him he jumps up and bites more. I don't know what else to do. Tonight, I had a friend take him out for me being I was going to be late coming home and he did the same to her. He goes on hour long walk everyday.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! German Shepherds are highly intelligent an highly trainable dogs. I recommend hiring a trainer and nipping this in the bud now. German Shepherds are also very large and can be aggressive to strangers as adults so being able to control Bentley is very important. I would start with sit, stay, and leave it. Purchase the gentle leader harness that goes on the muzzle. Use that for all walks. Bring treats on the walk and when he tries to jump have him sit. Once he sits he gets a treat. Jumping is unacceptable in a dog his size and is one of the hardest bad habits to break. He should not be allowed to jump on people. The gentle leader allows great control of the head. I hope this helps and I wish you the very best!
