JMO, My trainer told me say the word ONCE whatever you want him to do and then move him into that position ...no saying it a lot..My boy is VERY mouthy and has drawn blood we did the squirting....the knee, the yelling........he is a lot better but still drives me nuts with all this...He mostly listens to me but is also kind of aggressive like he thinks everthing is a joke...sometimes I dont help cause...I lol....yikes...He bit the vet trimming his nails and is well, um a problem child..when I get the cash I may take him to see a doggy shrink...seriously....I am off and on giving him Benadryl for allergies and like how mellow he is on it Sky but...he cannot live on drugs...or I would leave him on them hehe...i WONDER IF allerguies can make him act up
