This is Riley, my current favorite at save a dog. He has the personality of a dog I would adopt, very lively to see you, jumps on you etc. He'll play, although he is not very good at tug, I think we could work on it. He is actually very easy to rile up and he'll be a great jogging partner. He responds pretty well to people's voices, he was really engaged at looking at another dog that was making noise and when I called his name he snapped right out of it and came over to me, tail wagging. He plays VERY rowdily with other dogs, he has one good dog friend there that he plays rough with and he was very interested in meeting the other dogs but when he'd go to them he's do submissive posturing so he was not disrespectful like some rough players. He can also calm way down. I showed him to one family when he was tired (they were there all day so they saw both sides of him) and he walked right onto the woman's lap and curled up. Their son wanted him on his lap and I didn't think he would mind so I tried to entice him over and he was far too comfortable so the mother tried to push him over onto her son's lap and the dog didn't even move, he just let her push his front half towards the boy and he basically was face planted into the kid's lap because he never lifted his front paws so his face and chest were in his lap and his front legs were out behind him, he couldn't have cared less lol. He was quite content in his awkward position. I did bring his front legs onto the kid because the poor dog looked so uncomfortable face planted into his lap. Then the boy layed down and Riley slid up onto his belly and layed on him. it was adorable, the boy REALLY wanted him, the mother and sister were divided between him and one other dog. ANYWAY I was wondering what mix you thought he was, I personally think the rescue's guess is bogus and so I slipped my thoughts to this family even though I'm not supposed to, the rescue's guess is no better than mine. He's full grown, about 40 pounds.
