Its too hard to determine which puppy is going to be a pet or a working dog. Typically, breeders don't breed for pets. They breed for their next show dog. The pups that don't make the cut typically are sold to other breeders or show people. The few dogs that make the pet cut are already docked.
I just think this is an unnecessary argument that countries are enforcing. Ppl should be more concerened about over breeding and animal abuse. And I also don't think government shouldn't dictate how a breed should look. It should be the breeders choice.
But that's my opinion :)
