My sister and I have become huge afficionados of dog shows. We watched Westminster over the last two nights (unfortunately since several hundred miles separate us we weren't actually together) and it was quite fun and educational. They give a good overview of how each dog relates to people, like how the Scottie displays obvious superiority to its people, and Bull Terriers will join you on the couch after an active puppyhood. I have a hard time believing that dogs are all the same species. Look at a Chinese Crested next to a Neapolitan Mastiff and you'll see what I mean.


Chinese Crested


Neapolitan Mastiff (this was the breed that plays Fang in Harry Potter)

How can these both be classed as "dogs"??? Cats don't have as much variation. Long hair, short hair, long face, squishy face, but all around the same basic size and shape. Definitely cats. Even the Big Cats pretty much look like cats.
Here is another example, and then I rest my case:


BARK LIKE A DOG
off the leash and on your bone!!!
