are local dogs better than the hybrid ones?

I hear that hybrid dogs are much more stronger. They don't easily get diseases like canine distemper or parvo virus. And they say that hybrid dogs are smart, too! I don't know what you mean by local dogs. You mean purebred dogs? They are less aggressive than hybrid ones but need special care.

What do you mean hybrid dog or local dogs? Any dog can be afflicted by diseases like heart attack, high B/P. I have heard that if you feed people food then you increase the animals chances of having the same disease as people do. That means they are exposed to the same things we are. Something to think about.
