Thanks for using Petco Pet Education Center, formerly Petcoach! Usually these behaviors can be corrected but this usually requires in person training by a qualified dog trainer. I recommend you consider contacting a qualified dog trainer to work with you in person. Good luck and have a good day!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. At 2 years of age, Jalen is still at a good age to train. I would recommend behavioral training with a certified trainer / behaviorist. If that is not an option, I would recommend using a pinch collar or gentle leader collar to help train. If she is anxious and high strung, I would also recommend using NaturVet Quiet Moments Calm Chews with Melatonin, which can be found online or at your local pet store. You can also use a spray bottle filled with water and whenever she barks or begins to become aggressive, you can spritz her in the face and say "off" or "down" and when she follows the command, reward her with a treat. A trainer is most likely your best option though for faster results. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Training a disobedient large breed dog with bad habits can certainly be happy. However, in the end, the use of positive reinforcement will always reign supreme. Depending on what motivates Roscoe most will need to be what you choose to make Roscoe want to listen. I think this is a perfect case for clicker training. A clicker is a device that makes a clicking noise when you press down on it. Basically you want to first teach Roscoe that the click is associated with something good happening, which is called "charging" or "priming" the clicker. Once Roscoe understands that the clicking noise is associated with food or treats, you will be able to use this tool to your advantage. You should carry the clicker with you at all times and make sure to use it any time you are rewarding Roscoe. In terms of the jumping and mouthiness, you need to be very careful not to inadvertently reward inappropriate behavior. I realize that that gut reaction to something jumping or biting at you is to yell or push away. Unfortunately, this is not going to get the picture across to Roscoe. Instead, what you want to do is simply turn away or move your hand away. Continue to do this until Roscoe stops this behavior on his own and sits calmly. It is at this point that you want to click and reward. Dogs that are extremely disobedient sometimes need to have more strict boundaries than other dogs so that they be good pets. It is possible that you may eventually have to train Roscoe so that he knows not to enter your personal space until you have given him permission. With respect to biting, obviously this is an extremely bad behavior for a large breed dog. Rather than saying no, you will want to deflect his attention to something else. I would teach him the "touch" command. Since he tends to bite, you will want to train him to touch something like a stick or a rod of sorts. As soon as he starts to do the biting thing, you will want to get him to touch the object. If he does this, click and reward. With repetition and consistency, this should resolve the issue. In regards to walking, pulling can sometimes be resolved with a change in the type of collar. Some dogs do better with different types of harnesses or gentle leaders, while others do fine with conventional collars. Some even require choke collars, though I usually reserve these as a last resort. You should be teaching your dog the heel command, and be using the clicker in this case as well to reward the appropriate behavior. However, until you figure out what type of collar / harness works best for Roscoe it will be difficult to train him appropriately. Behavior issues are often complex and somewhat difficult. Don't be afraid to go out and get a trainer or go to some obedience classes. You can even speak to a vet that has some interest in behavior that is willing to work with you. If there is anything else that I can do, don't hesitate to reach out. I'd love to work with you.
