Jacks are awsome dogs,
My buddy was in africa hunting 5 years ago, hit a big Kudu but bullet smashed on some shoulder bone and the tracking was getting tough.
The PH sent a tracker to "get the dogs" Dan waited thinking these dogs would be some wolf like animal that could take down a zebra.
Here the tracker shows up with 2 jacks, and Dan starts laughing and giving the PH a hard time about his "toys"
So Dan says off go those 2 jacks and they start to follow them, after about a mile walk they her the Jacks yapping and carrying on. The PH and trackers start running and are telling Dan to hurry up.
Dan said when they came around the brush 75 yards away was this Kudu with one jack clamped on it's flank and the other clamped on its neck. The Kudo was jumping around trying to shake them off.
In that moment of a **** storm the PHs only advice to Dan was
"You shoot one of my babies and the price of that Kudu doubles"
He fell the kudu and the dogs came away unscathed.
