You can almost guarantee that when everything has been paid for, including the often forgotten increased fuel costs of heating / cooling pups, and washing and drying - the breeder is making very little, if any money out of it.
Obviously, there will be some breeds where less health testing is required, and if by their nature they are fewer in numbers, then there might be money to made from a litter - but honestly - all in all, it's not done for the money in any breed
Knowing the questions to ask and the correct answers required is a must
http://www.champdogs.co.uk/ is an excellent source of information on health testing, because against each breed, they list whether the dogs in a kennels ownership are health tested, and give an overview on each of the conditions - however, in terms of "up to date" - on things such as eye tests, for example, it relies on the owners to send the up to date information to CD for them to update.
Eye tests should be done annually, whereas DNA tests are 'once in a lifetime' tests, as are hip and elbow scoring.
You must also take into account the complexities of results, such as what is a breed average, which can range from 5 in some breeds to above 40 in others.
DNA results - is a condition dominant or recessive? If recessive, providing one parent is DNA clear - you can never produce affected offspring.
Questions to ask yourself if you're considering it...
1 - I love/will love my new pup... do I want it to die from something that could have been guaranteed preventable by genetic testing?
2 - I love/will love my new pup... do I want to increase its chances of having a life long debilitating disease that could have been screened for (e.g. hip dysplasia, annual eye testing - no guarantees, but bettering your chances).
3 - I love/will love my new pup... do I want its first few weeks of life to have been miserable, cold and dark?
4 - I love/will love my new pup... do I want my puppy to suffer?
5 - I love/will love my new pup... but I want to help these poor puppy farmed puppies.... should I help the "farmer" breed more, or should I get the same pup from a rescue who helps them?
6 - I love/will love my new pup... am I willing to risk his life just for the sake of a few €€'s?
7 - I loved our old dog and he came from one of these places, but would I want to risk it all again, just on the offchance that I am one of the lucky ones?
Everyone just needs to think before they buy....... IF THERE WAS NO MARKET, THERE WOULD BE NO BACK STREET, PUPPY FARMING, UNTESTED BREEDERS OUT THERE
JUST REMEMBER YOU GET WHAT YOU PAY FOR. SAY NO TO BAD BREEDING AND HELLO TO HEALTHY, TESTED AND VET CHECKED PUPPIES.
