It must be nice getting a massage from tiny paws!
Buster, a bull mastiff mix, and Beyonce
, a 3-lb. dachshund mix, might be vastly different in size, but they have a mutually beneficial relationship: they're pals.
A "miracle" puppy once considered to be too small to live, Beyonce has grown a considerable amount from the 4-oz. dog she used to be.
And Buster's not the only friend she's made since taking up residence at The Grace Foundation in El Dorado, Calif.
Now 5 months old, the petite pooch is also friends with Cat Stevens – a kitten twice her size.
