ooooh ok ye .. i know a lady who hates those although she has a good reason .. she said cuz when the dog pulls their neck kinda goes side ways and apparently damage or harm a muscle or something.. not sure cuz i only heard i'm not a professional but i've never used one but i've seen dogs who hate those things hehe

it's very funny they roll their heads on the floor and try to take it off against our body.. i find it quite funny hehe
