Well Most dog breeds are a result of human selection. Existing dog breeds began as mixed-breeds! either random-bred or by deliberate crosses of existing breeds. Studies that have been done in this area show that mixed-breeds on average are both healthier and longer-lived than their purebred cousins. This is because current accepted breeding practices within the pedigreed community results in a reduction in genetic diversity! and can result in physical characteristics that lead to disabilities

Introducing another breed to improve the health of a particular pedigree of dog is not helping. In simple terms: Once mixed (introduced) it's mixed, likely to inherit issues from both breeds and create others. I actually know some women with mixed breeds who have spent too much free time during these last 15 years with serious vet visits for issues caused by genetics. Things that they didn't have any idea would happen because they don't know the pedigree line of their dogs. They think I'm nuts for believing in purebreds.
Bless them for trying to give these mixed dogs a good life, but I'm not a believer in mating different breeds intentionally. I do know that accidents happen when owning two types of breed, and some are extremely cute, but to do it intentionally...NO. It serves no great purpose to add something else to current problems. You don't know which side the dog will inherit it's traits from. There are vets, scientist, and others trying the argument that mixed is better, but with enough breeds to choose from already, IMO people should be trying to make the future for purebreds healthier within the current breeds.
Oh and those dogs didn't live for 15 years. They died early and the owners just went and saved another mixed one, and inherited problems...again. |
