I’ve fed my coursing dogs loads of hares, and I’ve never had them try eat a hare once it’s killed and caught it… same as when I drive home with rabbits and hares in the back.. they know not to touch them. Mind you, I train all my dogs to a pretty decent standard, so maybe that helps. I’ve seen some coursing lads, who’s dogs shit in the back of the van. They would probably eat an hare as there so untrained it’s like taking a wild animal out ???
