Do all dogs have tails or are they cropped?

Not all dogs have tails. Some dog breeds have naturally bobbed tails, meaning their tails are short or non-existent from birth.

Here are some examples:

* Bobtail breeds: These breeds are known for having naturally short tails. Examples include the Bobtail (Old English Sheepdog), the Welsh Corgi, and the Brittany.

* Tailless breeds: These breeds are born without tails. Examples include the Manx cat and some breeds of cattle.

It's important to distinguish between naturally short tails and cropped tails. Cropping is a surgical procedure where a portion of the tail is removed. This is often done for cosmetic reasons, but it can also be done for functional reasons, such as to prevent tail injuries in working dogs.

However, tail cropping is a controversial practice, and some countries have banned it.
