They're fine to feed your dog mate, My terriers eat a lot of raw rabbit.
I freeze the rabbits before I feed them for a few weeks, as I usually have quite a few stocked up in the freezer. I just defrost them and then sling them a quarter of the rabbit along with a bit tripe, heart, liver or mince beef, all depends what I've got in or what they've had the day before.
Just make sure you gut them, some people leave the skins on them, but I skin mine and feed them whole (bones as well, essential for calcium).
All the best with it.
