Whisky Cross is a Rear Cross that is executed at a very tight angle, with an approach from the side or backside of the jump. Your dog is unable to commit to the obstacle early as he won’t see the bar on approach, which makes the technique challenging for some dogs.
Whisky Cross is one of the few techniques that requires some teaching for your dog to understand the handling. The more obstacle focus your dog has, the easier this technique will be for him.
