We have three young boys and felt we needed a dog, too. We had cats for a few years, but when our oldest son was born, one of the cats showed her distaste by puking next to his crib. We found new, happy homes for the cats shortly afterwards.
Three years ago my wife said she found a puppy she just wanted to look at. When I arrived home from work, I discovered we had a new pet, a miniature black poodle. Her name is Bella.
