Is that an actual statistic? I have one door that goes into the fenced part of our yard, and 2 that don't. So statistically, our dogs have more chances of being let outside into a non-fenced area. Also, our driveway isn't fenced in. So every time I take a dog to and from the van they could get loose and hit by a car. Not to mention every time I take them in and out of the van out in public. So I have a fenced yard, but statistically speaking, my dogs have just as much chance of being hit by a car as those without fenced yards. Oh, and I said those that say no right off... without bothering to even question the adopter. You could make yourself crazy with all the possibilities of your dog being hit by a car. Not everyone that it happens to is a bad owner... but it seems that in a lot of the cases I've heard of it was people out in the country with a lot of land that let their dogs 'run free'.
