I know someone who has friends with standards that have caught and killed (really killed) adult opossums. There are two and I gather they tag team it to get larger quarry, but they also eat a fair amount of bunnies. We have bunnies in the yard this year that have been really using us as their home base. Bunnies have been chased but not caught so far. Peeves is just too slow as an oldster. Lily is too polite. She has a prey drive, but leaves the chickens and the bunnies if I tell her to. Javelin has a strong prey drive, but better obedience including a super recall and will return to me if I see him take off after a little critter.
I don’t know if he would or not. He certainly enjoys chasing them. He makes no attempt to eat the opossums he catches and “kills”. He carries them around until he’s bored, and miraculously they come back to life and disappear. He has eaten a baby squirrel and a frog, sights I would like to un-see.
Pretty normal, please do not allow this since it is not an ethical thing to do to a baby animal. Dogs are already given food and do not need to kill and eat animals. Avoid leaving your dog alone in the yard, not only will it save countless lives of small critters, it can protect your dog from larger animals, people and the elements.
