Yorkies are terriers and do have strong terrier instincts. He's going thru a stage at this time (being 5 months) and it should improve down the road. Use only positive training and have him neutered as soon as his permanent teeth are in so you can have any retained baby teeth removed at the same time. That will help you avoid placing him under anesthesia more than once. I think neutering him will also help.
