This is a favorite topic of mine! Yes, I do hips, eyes, heart and thyroid on all breeding stock. And I have removed a few dogs from my breeding program because of it! Had one dog with juvenile cataracts (can't be seen by just looking, but is progressive). Also bought a 4 year old dog, no symptoms of anything, but routine screening for hip dysplasia revealed that he had severe dysplasia. A vet will tell you that there is no correlation between severity of the disease and clinical symptoms - some dogs with mild dysplasia will be crippled, and some with severe (like mine) show no outward symptoms. When I bought him, he had already been bred, as neither his breeder or previous owner did any health screening. He showed no symptoms until he was about 8, and then he deteriorated very quickly. That taught me first hand that there are many things that you won't 'see' without doing the tests.....
On this board there have been cases of hip dysplasia, eye problems, heart problems, and epilepsy - all hereditary problems. You can't say "I've never had any problems in my line" unless you test for it!!
Here's an example - Take one hotshot coondog, wins a couple of big hunts, finished to Grand by 18 months old - now he's offered at stud (without any health testing). Produces a few really good puppies, and gets bred a lot more.......by 5 years old, he goes completely blind from the PRA that could have been diagnosed at 18 months, if he'd been checked. So now you have several hundred dogs dispersed into the breeding population, carrying a known hereditary eye disease that causes blindness......now what happens if two of his brothers were also popular stud dogs, never came down with PRA, but were carriers, and passed it to their offspring. Within a generation or two, you can suddenly have a widespread problem that is hard to breed out.
The way I look at it, the cost of doing all the tests that I do, is less than the selling price for one puppy, so I can't see any justification not to do them, it's just one more tool to help breeders breed the very best dogs they can.
