Not unexpected at all. People haven't been manipulating most species long enough to see dramatic speciation such as we see evidence for with much longer timespans. We have been manipulating things with short reproductive cycles, such as fruit flies, and bacteria, and we have seen species change with them. But with Dogs and Cats, there simply haven't been enough generations yet.

No, we don't have faith, we have evidence. Lots and lots of multidisciplinary overlapping multifaceted mutually corroborating evidence. And not a single instance of anything which completely conflicts with the model (no fossil lizards in precambrian rock, no whale fossils before the cretaceous, no equus before eohippus, no people before primates, and no Boeing 747's before Kitty Hawk. Not a thing out of place. Anywhere. Ever.
