Sumo is a sweet-natured gentle boy who just turned 11 this year. We sometimes call him "Grandpa-puppy" because he is starting to slow down a little but still has his regular spirited playful moments. He loves to be with people but is quite independent. He loves to play, loves a nap, loves to swim at the beach and loves to fossick and sniff all the things on a walk. He's great with kids and most dogs, but he can get bowled over by larger dogs (he's had two ligament reconstructions on his back legs).
