Not the ones that keep these threads alive. The dog breeders create a fascinating variety of dogs. But they always get dogs. Everyone knows this and NOBODY is arguing about it.
As you said, things change.
The sticking point is where the dogs came from, what mechanism introduced the change from what they were to dogs, and where the long series of proto-dogs is that connects dogs to slime.
Shalom.

Humans have not been breeding dogs long enough for speciation to occur. If you want to see speciation in the canidae, you can find some very nice fossil series. It's one of the best documented in the fossil record.
Google "canidae evolution" (no quotes). You'll find a number of excellent articles on the subject.
Give us another 100,000 years or so of dog breeding, and new species will emerge. They will still be canidae, but will not be able to interbreed (the definition of species).
Give it 100 million years, and who knows what will be there.
