When they aren't looking
A Shorkie adults tail only gets cut when it is frightened. A puppy does not.
for looks
This should rather be done by a professional as it can be easy to cut the dog.
it means he/she's cut or hurt smart one. Or if its a female she's probably on her period
At a similar age to when you had your coccyx severed.
No it will not grow back. Dogs do not have the ability to regrow limbs.
You really shouldn't "dock" or cut a dog's tail off. But as far as natural length goes, it depends on the breeds.
YOU DON'T! You need a veterinarian to do this properly!!
No, never. Bostons don't have much of a tail other then a small corkscrew and you leave it alone. If you get a Boston with a tail it is not full bred but don't ever dock it. I doubt a vet would anyway.
I used neo sporin ointment on my puppy's tail when I got her because the breeder was too cheap or ignorant to have a vet dock her tail and it healed OK.
"Why do i need to cut my tail" said the monkey
Tail bobbing should only be done by a licensed vet, since it is major surgery. Both skin and bone needs to be cut, and the skin stitched to cover the wound. Tail bobbing is loosing popularity in the United States, but is still required by many breed standards. Some rat terrier puppies are born with bobbed tails. Mine was!
