BACKYARD DOG TURNED HOUSE DOG. Spike was a backyard dog who never got much attention, but he's come a long way. He now walks quietly on leash, right beside you, and is fully housetrained. He's still a little head-shy and doesn't yet come on command, but - with a little more TLC - he will blossom into a wonderful family dog. Spike weighs about 35 lbs. He gets along well with other dogs. If you have prior dog experience, Spike may be just the dog for you.
