A friend for Barney??

Pete and I keep going back and forth about getting another dog. A friend for Barney to play with and to get into trouble with while we are both at work. We both constantly check the Pasadena Humane Society website to see if there are any cute dogs. We wouldn't get a Pit Bull or a Chihuahua, even those are the most needed dogs to adopt, but more of a smaller dog like Barney's size. We'd want to get a dog that is at least 2 years old already cuz then we won't have to worry too much about all the puppy hijinks. The dog would have to be pretty mellow to be able to mesh with Barney's personality too. Then there's the whole baby factor to consider. Is it wise for us to throw in another living thing that needs taking care of? But then again, will Barney need a friend cuz we will be too busy taking care of the baby? All the "what if's"!!!
