Some adaptations of a cocker spaniel?

It is cutting off of part of the length of a cocker spaniels tail, by means of amputation, usually 4 or 5 vertebrate back.

In some countries, Docking is illegal, some states in the USA have considered banning the practice.

It is necessary, only if you want to register the puppies, with club kennel like the American kennel Club.

Amputations of the tail, are done fairly soon depending on size and health of the puppies.

Veterinarians usually perform the procedure, as it is painful for the puppies with possibilities of complications.

Biggest worry, is to keep the area of scaring clean & sterile, so infection does not sit in.

Again Docking a dogs tail is risky, you are cutting through flesh, muscle, between vertebrates, and the spinal cord it's self, having to leave enough skin to hang well over.

Some Kennel owners will perform the procedure, it important that it is done right, a poor job can cause issues and complications the whole dog's life.
