While a highly sought after stud can have a big impact on the breed, the chances of it spreading disease like wildfire is pretty remote. Word does get around and the demand for a stud that was producing sick pups would go down really fast.
Now, on the other hand, a miller with a stud and 20+ breeding bitches could produce a ton of sick pups and never give it a second thought.
For the OP's question, there is no pat answer. The simple answer is that it's not as simple as that. I don't think you'll get a true perspective by just asking single questions and expecting single answers. Try to look at the whole picture, get a good understanding of all the aspects of breeding. Then you have to apply it to the dogs you have or the dogs you are seeking. While there are some general 'rules', breeding, like whelping, always has its unique circumstances to be considered. |
