i second that... slightly different scenario but i had a bloke the other day, someone i know who has had some very large, bull headed Dobermans, tried to Alpha Roll Stella!!!!!
WTF! !! what he does with his dogs is his business but he sure as hell aint doing it with mine! let alone a foster dog with issues!!! i demanded he let her go immediately, which he did, and appologised. i reminded him that not all trainers agree with the dominance/alpha roll theories and that he was wrong to assume that it was ok to practise his beliefs on a dog that wasnt his, without permission from the person holding the lead. (thats the polite version anyways!!!LOL)
