Hi, I would just like to say that above all you should be concerned about the stud dog's health. Every breed has it's problem you should focus on but there is one general issue that should concern all breeds and that's Herpes - especially if you decide to breed with a popular stud dog that has been bred with many different bitches. My friends bitch died of Herpes after giving birth. None of the puppies survived. She had autopsy done that proved the cause of death as Herpes. The thing to know is that you can prevent this by vaccinating your bitch before mating her. There is a particular vaccination scheme for this you should check with your vet. Usually the male dog doesn't even have to have any symptoms of Herpes and could be just carrier.
