This can be very common behavior for young puppies. It is important that you initiate training with your dog now so that his aggressive tendencies do not continue into adulthood. Somethings you can do to discourage his nipping and aggressive behavior are to try and redirect his aggression by giving him a toy to play with and bite on instead of using your hands and fingers. Also, when he missed behaves firmly tell him no, put him down and walk away and ignore him for 2 to 3 minutes. After that time you can start playing with him again and if his bad behavior returns ignore him again. If you continue to do this he will quickly learn that when he misbehaves you will not pay attention to him so he should stop the bad behavior. It would also be beneficial to start training him with basic commands like sit, stay, and come. This will help establish your role as the dominant one in the relationship. Also be sure he is getting plenty of exercise by taking him on 20 to 30 minute fast-paced walks at least 2 to 3 times a day. This will help drain some of his energy and make him be able to focus on training with you better. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. That’s the one.
