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.
