This was Gus, the Wonder Dog, my family's yellow lab. He was about 19 in this picture.
We adopted him when I was about 10 and he was 3. He died earlier this year.
He loved cats. Two of my dad's calicos took to suckling on Gus's elbows after they were weaned, and kept doing it until he died. He treated them like little puppies. He'd snuggle up with them and they'd just purr and purr.
