The Wall Street Journal's real estate section has a good piece on what dog owners should look for in a home. I especially liked the advice on electronic fences, which seem like a good idea to many people but have some definite cons: to name just two, they don't keep other people out of your yard and they don't prevent other dogs from coming into your yard and attacking your dog.
If you're a dog lover deciding where to settle, consider some of these dog-friendly cities. Dog Fancy has also ranked places friendly to dogs. Of all of these, my dog-tested favorites are Vancouver, Seattle, San Francisco, Long Beach, and San Diego. Just remember that water dogs do best in Vancouver. Luckily, my greyhound and Cavaliers have never minded the rain. Maybe that's because they're all of British origin and some ancestral memory tells them that rain is a normal state of affairs.
