How are chihuahuas and St. Bernards the same species?
In: 1
Seeing as dogs are descendants of wolves, the thing that perplexes me is how did wolves eventually filter their appearance from breeding? Wolves have a very homogenous look about them so if they are the original “source”, where did the bear like features of a Chow Chow come from? And where did the rodent like features of a Chihuahua come from?
