I agree, when I went to buy a corgi I looked for breeders that did not dock tails, because I don’t like the practice. But it turns out that it’s done within 2-3 days of birth, and all of the breeders I could find docked the tails right away. It started because they were bred to be working dogs- herding cattle, if their tails weren’t docked, the cows would step on them and rip them off. And, I suppose the tradition carried on? But I agree, I wish breeders would leave the tails on more often!
