Doberman Health: Hips and Elbows

In my "Picking a Breeder" page (you'll see it up top there), I state that you want to look for a breeder who has gone through either OFA or Penn Hip for their dogs. Hip dysplasia and elbow dysplasia are crippling and painful conditions that can affect dogs. In addition to the (to me) obvious quality of life concern, a dog crippled by one or both of these conditions is not a dog that does well in conformation competitions (or should not, anyway), and cannot adequately perform in working venues.

Where do puppies come from?

I was in a mall today, and that mall had a pet store. Not just a pet supply store, but one that had that row of cages, separated by windows, with puppies in them.  You know the type.

There was a Puggle, and a Morkie, and a Chihuahua, and a Pomeranian (though the people standing next to me thought it wasn't a purebred Pom; I thought it was, but held my tongue).  There was a Bernese Mountain Dog, and an English Bulldog.  The smaller breeds were all $700, but Berner was $1999, and the English Bulldog had a sign that said "Serious inquiries only."

So, where did these puppies come from?
