Golden Retriever Puppy (up to 1 year)
I have a 7yr old Golder Retriever (Scotch), he weighs 100lbs.
I decided Scotch needed a friend so I got a 10 wk female Golden, named her Bella.
Introduced them in the back yard, Scotch didn't like her much, lots of growling and showing teeth. I figured that was normal with the I am in charge...
