I've never seen any rabbits in our backyard. But the dogs love to chase the birds and squirrels. We do our best to make sure they don't kill any of the animals, mainly because we foster wild animals, so it would be even harder to keep them in the house with the dogs. I know one time a squirrel electricuted itself and the dogs picked up, they dropped it almost right away since 5 REALLY loud voices came at them!
