Could a six month BC pup kill an adult rabbit???

Asking to find out. I came outside after like 10 mins and my pup was playing with a rabbit carcass. There was not blood in the yard at all (it was snowing). The rabbit was pretty big size and stiff when i scooped it into a yard bag. There are plenty of bunnies under our deck and running around the neighborhood. She could have pulled it out from under the deck. What do y’all think?
