what's the reason the poor dog lives in your garden and not in the house? it's a dog, not a chicken. as for training, get a trainer or start watching a lot of youtube videos. your only going to get out of your dog what you put into it.
Well it is because of my family's religion. Dogs are banned in houses -_-. As I said I can't get a trainer because there is no nearby. I am trying to do my best. By the way he never gets seperation anxiety. Not really useful but thanks for your comment.
