Welcome to YT..and congrats on your new puppy...my daughter own a 80 lb black lab
and a 3 lb yorkie both male, Buster (lab) was around 2yrs when Cowboy 18 months old went to live with them..Buster has been both mom/dad to Cowboy since he arrived..although they have seperate food bowls Buster allows Cowboy to eat from his bowl if he wants to..they are so funny together..
I wish you the same luck with your baby & lab
