Someone I know recently got a dog. This dog, however, has no tail. How do you find out why the dog has no tail - was it born like that, was it removed, etc.
What can I look for that will tell me the cause?

You can check this list.
It may help you identify it's breed, to tell if it's a breed that genetically has stubbed tails.

We can't help with breed identification on here since there are too many variations, mixes, assumptions, and identifying qualities etc..
