Quick question, my boy seems to be a weak nerved dog. He is quick to growl and bark when someone comes to the house, but just as quick to back off when they try to meet him. I mentioned this in my last post, and also mentioned that he had been abused in his first home. I have seen INCREDIBLE improvements in him since I brought him home two months ago. Would it be fairly safe to say that since he has improved so greatly, that his weak nerve is due to the early abuse and not genetics? I am hoping that is the case, as I want him to be happy and healthy!
