|Turbo I would like to say that the likelyhood of genetic problems is exactly the same between 'fancy pantsy purebreds' and mutts.
If you put two dogs that are homozygous (Ex: Aa) for.. well, ANY problem. Then there is a 25% chance for Dominant (AA), 50% for Homozygous (Aa) and 25% for recessive (aa) for EACH pup. These two dogs can be purebred or they can be mutts, If you breed a GSD with a Rottie and they both have HD (Dominant: AA) then their pups are going to have it, regardless that their pups will be mutts.
If one of the parents was homozygous and the other recessive (Aa x aa) then there is still a chance of the puppies getting it, the only way that they wont have it is if they were all aa.
However, there is breed specific problems (vWD for example). Dobermans have a long history of this disease, with 50% being carriers, 25% being effected and 25% clear. So if you bred a Dobe that is a carrier (or effected) to a dog that doesn't have a strong history of it (uhh.. Husky, lab, ect?) then there is a less likely chance, but it is still a chance.
"The breeds who have vWD Type 1 and where a DNA test is currently available are:
Bernese Mountain Dog, Coton de Tulear, Doberman Pincher, Drentsche Patrijschond, German Pinscher, Kerry Blue Terrier, Manchester Terrier, Papillon, Pembroke Welsh Corgi, Poodle and Stabyhoun.
Any of those dogs, bred in whatever kind of mix you prefer, can still be born with vWD, regardless if mixed breed or pure.
Sorry. I just don't like it when people put down purebreds. A dog is a dog, and they all have genetics, some work in the favor of others and some do not.
Just because her dog was purebred doesn't mean it came from a good breeder, too, a good breeder would look up known problems of the breed and would have tested the dam and sire before breeding.
Chances are the parents had the same problems but they were over looked.
