Purebred Dog Training
The term ‘purebred’ is relative. No breed has been so isolated that it’s never mated with another.
But taken over the last hundred years or so, there are populations of Golden Retriever, German Shepherds and many others that have bred only with their own kind. As with any inbreeding program, the results tend to produce extremes, both good and bad.
The bad aspect is that, for technical reasons, genes that lead to undesirable conditions will occur more frequently the narrower the population. Instances of hip dysplasia in Golden Retrievers are more likely to be passed on if programs are careless. Fortunately, they rarely are.
