I have always wondered this about docking, if it's banned in certain country and a dog gets it's tail infected from a horrific injury, Is docking even allowed in cases of emergency like that?
As a matter of fact I have seen a rottie with a tail. I've met people who had to get a tail docked due to something happening like a tail injury and having to dock it slightly, I mean sure a docked tail is a docked tail but I've not seen rottie with stump. I mean my neighbors dog when I was younger his rottie had a partially docked tail it was not because of cosmetic reasons it was that something legit happened when the dog was younger. So medical emergency was the reason why the tail looked weird and funny but his tail was by no means a stump. In fact his owner refused to get the rest of docked on basis that cosmetically alterating a healthy dog was just dumb.
Only reason to dock a tail is if there is a legit medical emergency in regards to the tail not being viable to save or if half of it is literally dying. and only a small part can be saved.
My poodles tail may be docked but that is not something I or my parents did that is something that whoever bred him did and what people fail to understand is you can own a docked animal and not support docking just cause you adopt an animal with docked tail doesn't mean you are supporting docking, it doesn't make me a hypocrite to own a poodle whom my family adopted whose tail is docked.
My parents don't support docking the tail of any animal which is why when we got my border collie we never docked his tail, and our vet actually asked us to make sure we weren't doing that. He actually was relieved to hear we thought it was bad unless used in medical emergencies.
