I wake up and my dog is with a rabbit in her mouth

So I wake up and my dog is laying on the back patio covered in dirt with a rabbit in her mouth.

The rabbit’s not bloody, just dirty.

I know my neighbors raise and care for rabbits so immediately picked the rabbit up and brought it to my sink quickly before my neighbors came home and cleaned it off.

It was stiff and not moving but I know some animals play dead when they are scared I just did not know which ones.

I put the clean rabbit back in my neighbors rabbit cage with the rest of them and went back inside my house.

Not 30 minutes later I hear my neighbors screaming so I go out and asked them what’s wrong?

They tell me their rabbit died 3 days ago and they buried it but now it’s back in there cage
