Some breeds of dogs have a natural curl or bend to their tails. But others have been selectively bred to take this curl to an extreme, cork-screw shape. Dog breeds with curly tails referred to as screw tails include Boston Terriers, Pugs, Bulldogs and French Bulldogs.
The puppy's tail falls off in about 3 days. The 2nd involves the cutting of the dog's tail with surgical scissors or a scalpel, performed by a veterinarian. When done this way, it is normally done at the young age of 2 to 5 days. Anesthesia is not used as it is considered a risk at this age.
