My "little brother", is a yorkie/norwich cross. With Lucky the key word is "GO", he runs to get a drink of milk and a biscut! Then he's at the door waiting.
Got him for my folks when he was tiny(fit him in my shirt pocket). When my Momma passed in 2002, Lucky was who kept my Daddy sane!
Awwww...that's a great shot of you and your dogs!! I own and operate a private boarding facility, so I'm a huge animal lover. You obviously take very good care of your dogs! Nice to meetcha
