Tail-less doggies

While watching a man walk his boxer (which, true to its breed, has a short tail), Todd wondered:

"Why is the doggie's tail so short?"

I hesitated, pondering how to tell him that the dog's tail had actually been CUT OFF by us ruthless humans. But before I could say anything, Todd figured it out:

"He's a small doggie. When he gets bigger, his tail will be long."

Can't do anything but agree with that kinder assessment! :-D
