Det finns ett nytt lagförslag på gång i USA, "Dog Purchaser Protection Act"
Där står en text jag fastnade för, för i och med att vi fått doldafelslagen så tycks många valpköpare ha missat den lilla del av verkligheten
Some genetic diseases run in breeds as they do in some human families. Mixed breeds suffer from the same array of maladies as purebreds, but
they do so in a less predictable manner. Nonetheless, the degree of variation that makes dogs infinitely more complex than a machine also renders them absolutely impossible to unequivocally guarantee. As such, there is some degree of risk that must be recognized and knowingly undertaken in the purchase or adoption of a pet.
The good news is that the degree of predictability found in purebreds allows conscientious breeders to perform health screening tests on potential breeding stock and identify carriers before using them in their breeding programs. This enables responsible breeders to reduce the incidence of certain genetic diseases in their puppies and in their breeds.
For diseases with simple modes of inheritance, genetic testing allows breeders to totally eliminate some diseases. In some breeds, responsible breeders routinely x-ray their stock before allowing them to breed. Others screen potential breeding stock for heart or eye diseases and other
disorders that are sometimes found in their breed.
The bad news is that no screening test yet exists for many diseases and for some, the mode of inheritance is so complicated, the tests that have been developed are not very useful in predicting outcomes for individual progeny. The inheritance of diseases such as hip dysplasia is so complex
that, in many breeds, even the most conscientious breeders will find its total elimination virtually impossible. Hip dysplasia occurs in large and rapidly growing breeds and mixes; even when the parents showed no outward or clinical signs of the disorder, it can still crop up.
With new genetic findings and the improvement of screening tests and selection methods, the number of affected offspring can be greatly reduced; but similar to human medical progress, animal husbandry is not
a perfect science and total elimination is not always possible.
