Most certainly have to disagree with you on this one.
Why. Because the dog is more likely to obtain an injury in the pursuit of the quarry, lets face it how often would you request your dog to jump a fence, and how often would you slip your dog during a nights lamping, I guess the dog would be more times chasing bunnies than jumping gates, so when you balance it up, it’s worth teaching the dog to jump.
Who wants to be left lumping a lurcher over a fence in the height of winter, ya don’t make sense man.
