Humphrey the dog was a little standoffish when his parents, Samantha Tungul and Jeremy Rood, brought home a couple of rescue pups to keep him - and them - company.
"We call him Uncle Humphrey because he was always just aloof with them," says Tungul. "Never really bonded that much and kind of kept to himself."
They figured Uncle Humph would be more or less the same when the couple began fostering rabbits through their local shelter in Northern Virginia a couple of years ago.
They are so happy to have been so wrong.
"Humphrey is the best dog foster brother, paws down," says Tungul.
