does anyone have any tips on introducing a new puppy to an adult dog? our 7 year old wheaten terrier is rather put out at the new 8 week old addition to the family, its been a week and their relationship is not improving! the pup seems to make our Ted anxious, and every now and again he barks and growls at him, which is unknown as he is always very friendly to other dogs. I dont want the pup to grow up timid and scared, but i do understand he needs to learn his place! also Ted is a giant compared to Ozzy. Help!
