There are lots of 'older' dogs that would make good pets/friends. If I were you I'd DEFINITELY just go to the shelter and get a dog there. I don't think you guys would enjoy a puppy since you don't want a dog that is hyper etc... There are millions of dog that need homes.

We know about the 40 mile per hour couch potatos (how they put it at our local shelter) We looked at some, but they were no good.
What do you mean 'no good.' Dogs are like people. No one is any better than anybody else. Everyone is different and has different opinions, but we're all equal and that's how dogs are. They're are different kinds, but they still have a heart that loves unconditionally.
