Why don't some dogs have tails?

Answer 1

No, humans do not have tails. During embryologic development the embryo develops a tail, but it regresses prior to the fetal stage of development. However, humans have the last little vestige of the first bone of a tail. This is the coccyx bone and it is fused to the last sacral vertebra in the fused pelvic girdle.

Answer 2

The truth is that we do have tails! All mammals have a tail at some point of development. The Coccyx or human tail is simply very short and are not usually visible through the skin. The tail bones are very important for us as an attachment point for muscles.

Most animals tails serve some purpose, like keeping balance while they are running, helping them climb, communicating through body language, or displaying virility like the peacock.

We ceased to need tails when we began to spend little time in trees. Over time, a species expends bodily resources only on features that convey some advantage. because... welll we actolly sorta do have a tail it stops at well.. your butt

Answer 3

All vertebrate animals have tails although they might not be visible. Humans do have them too-about seven tiny vertebrae are fused together below the spot where the pelvic bone connect with the spine. I've had my broken before and it was really painful for a long time...not being able to sit for a week is a very bad thing...

Tails were originally used for balance and/or swimming but as they were no longer needed (like for humans) they got smaller and smaller.

Answer 4

Humans don't have tails basically because of evolution. It is believed that humans evolved from monkeys and from each phase, we walked on two legs more and more and no longer needed the tails for balance, their main purpose. So eventually throughout generations, tails got smaller and smaller until all we have left for our record of having tails is our tail bone where our tail should be.

Answer 5

The tail bone on a human is a vestigial structure, meaning it is the remains of a body part that we once may have had during the process of evolution. Just like its name implies, the tail bone could very well have been a tail at one time, but it is unclear how long it would have developed or grown. As humans began to travel and use two feet, a tail would have became useless and shrunk over time. Although this has not been proven, it is a possible theory for the existence of the human tail bone. Today, the tail bone serves as a support structure for muscles and acts as a shock absorber when sitting.

Answer 6

Almost every breed of dog is born with a tail of some length. A dog that has no tail whatsoever may have had its tail docked as a puppy or amputated due to an injury.

Answer 7

All humans do have a tailbone, just that some tailbones may not be visible
