I just got a 10 week old Cocker puppy for my wife, and we are already pulling out our hair.
A little background, my wife and I already have an 11 year old cocker who is very submissive, calm, quiet, etc. The issue is that she runs away from the puppy which is causing the puppy to run after her and try to nibble at legs or ears. I feel protective of the older dog and grab the puppy up, if I dont do this the older dog runs away and jumps on the sofa. I am not worried about the nibbling as I am sure that will go away and she has already started to understand that you can not nibble at fingers, feet, or the other dog. How do I get my 11 year old cocker to stop running and become the "alpha" dog. (I am not sure if this is the right terminology, but I hope everyone understand what I mean.
Thanks. Oh and for the name, Lila is the puppy and Ruby is the older one. :p
