There was a time when no one thought twice about letting their dogs roam the neighborhood. A fenced yard was almost unheard of. If you grew up in the 1950s and '60s as I did, you may remember those times. Dogs were well socialized, loved kids, and it was no big deal when the neighbor's dog came over and visited your female dog in season. Of course, they also chased cars, got pregnant a lot, and occasionally although rarely bit someone. You may also remember, as I do, a long list of childhood pets who got shot, hit by cars, or simply vanished, having fallen victim to who knows what fate. Today, our canine companions are more likely to be spayed or neutered, vaccinated, and responsibly contained. As a result, they tend to live safer, longer lives. But having a fence isn't always the be-all, end-all solution that it seems to be. Fences can bring on a host of challenges that our parents never faced with the family dog a generation ago.
