Same thing in my garden eevry year, slinkycat.
My staffie 'caught' a mating pair on Monday night. The male shot off into the shrubs and the female stayed there in a ball. The staffie goes mad, trying to bite the hedgehog and trying to pick it up. We have to make her leave them alone.
Our last dog, a staffie cross, who was much bigger, used to pick them up and bring them into the house and drop them in his basket.
So everynight this week, it's out with the dogs last thing and keeping an eye out for hedgehogs.
