The jack russel terrier is a good example, which if you watch a dog show now you'll note it is called parsons russel terrier.

They too change names just not as often.

Maybe an American reptile Club needs to be started, with stud books, descriptions, pedigrees, etc.. Then we can have reptile shows on TV and walk them on leashes LOL ( I am kidding of course ) Hope i didn't give anyone an idea now.
