Bob,
I wish you luck in your search for a dog. I've never heard of a Biewer dog before but it definately looks cute. While small dogs may seem "girly" you will love the companionship they bring and energy.
Here is Baxton, I've had him for just about 5 months now and I have loved every minute. Stays by my side wherever I go, sleeps with me at night, loves car rides, and is a big helper when detailing. Good luck, and I can't wait too see what you guys decide on. Have you looked into West Highland White Terriers? Also great dogs, popular in the Detroit area.
