Interesting Cross Breed on Craigslist

You have a better chance at finding a healthy breed if you look for one bred for physical activity (hunting, herding, pulling, racing, etc) than one bred to be a lap puppy. The stresses put on the dogs to meet the physically active breeding goals typically weeds out those dogs that have health issues.

I think that *might* be true if you're talking of working/performance lines within those breeds. For instance, IME Labs from pet lines don't seem to be any healthier than the average lap dog. Field bred Labs probably would tend to be healthier than an average lap dog or an average Lab from pet lines.

But there are likely exceptions to that. For example, the high incidence of cancer in Greyhounds, even though the overwhelming majority, at least here in the U.S., are bred from performance lines.
