The lifesaving sled dog Balto had genes unlike those of dog breeds today
The idea of purebred dogs is a fairly recent concept and a pretty terrible one. We understand the ramifications of inbreeding in humans, so I don’t know why it seems to be such a cognitive leap for folks to understand why inbred dogs are less healthy and often develop undesirable traits (alongside some inbred desirable ones).<p>I have had many dogs over the years a number of mutts and a number of pure bred dogs and the pure bred dogs have almost always had both personality and health issues to varying degrees. The mutts tend to have a more even disposition and are longer lived.
