There known as Hampshire diamonds round here. There is a lot of land which is nigh on unrunnable if you've any respect for the dog, still accidents happen on 'safe' ground, I've had 2 dogs nearly bleed out whilst lamping being sliced by flints when turning, my vet reckons my bitch looks like a patchwork quilt, they won't get hurt if you leave them in the kennel, but they won't catch much either.
Just about sums it up......
