The annual canine obedience competition was only a week away when suddenly the dog trainer’s union went on strike. Non-union workers were hired to finish up training the dogs for the show. Training was going well as the replacement workers taught the dogs about fetching, rolling over & sitting.

Worried that they may lose their jobs entirely, the striking union members began to march with protest signs outside the training arena. This all began just about the time the dogs were supposed to be learning to follow the command to “heel”.

Hearing the striker’s chants and recognizing their real trainer’s voices, the confused dogs would no longer follow the substitute trainers through their paces.

This came as no surprise to anyone because we’ve always known, “A scab will never heel if you picket.”
