Need some suggestions on dog training. We have a 2 year old male pit bull that is starting to have some "issues". He's non-aggressive, but you wouldn't know it if you were to meet him from afar. He has now found his voice and barks at anything and everything. He's soooo very strong as well. I'm afraid to walk him now because I have balance issues from my MS. He's a sweetheart but also stubborn as heck. Need a good trainer, a patient trainer not only for our boy (the dog) but me as well:) Thank you in advance.
