Hello, We have a 9 year old retriever mutt. He has been the the best dog I have ever owned. He has always been a little flighty like afraid of the vacuum. Lately he doesn't listen at all to me. I have to force him outside to go to the bathroom. When I try to put him out today(at 2:00pm after all night) I wondered if he might bite me when I tried to move him along with his collar. He doesn't get hit. Just tell him to move it(not yelling). He has a clean bill of health from the vet. He is fine when my dh is home he is just like this with me. He was raised by me & dh. I have been stay at home his entire life. Has anyone had this happen with an older dog? I do want to chance a bite for me or my kids. I was bit by a chow in the face as a child so I know what that is like.
