Really..... listen,.... Yes they felt it. I was there. I assisted the vet as he did it. they were two days old when I had their tails docked. I did it for cosmetic purposes. To conform them with the standard. I went to the pound two days ago, both boxers I saw there did NOT have their tails docked.I have heard plenty of boxer owners regret not docking the tail but I haven't heard one person regret docking the tail. All the pups were fine after about 3 hrs. I was with them the whole time.
