I love it when people come in with these comments with zero context lol. Did you know that some people adopt dogs from previous owners? You're gonna give someone all the smartass energy you can muster and they're gonna answer with "we rescued him from an abusive home and nursed him back to health and resocialized him but thanks for your brilliant advice"
OP probably isn't even the source of the video. Assuming it's theyr actual dog, how do you know they didn't get the dog that way and are actually against eat cropping and tail docking?
