Hello New to this site! We are the proud owners of a 13 week old Cocker Spaniel. He's doing brilliantly with all his training and is a happy outgoing pup, great around people, children and even the cat. He's loving going for walks with us but is petrified of any dogs we come across, even when they are very gentle with him. He tucks his tail between his legs, crys and trys to run away. We've never owned dogs before and we're not sure if this is normal or how to help him with this. Any advice greatly appreciated!
