How do I feed my dogs sardines?

I have an 50lb adult dog and 20lb, 3 month old puppy. I feed them a prey model diet, but I am wondering how to feed them sardines. I've never bought them. Do the canned sardines have bones in them? If so, do I just give the whole thing to them? Won't the fish bones cause a perforation in the intestine? FYI, I do feed normal bones, but something in me makes me wary of fish bones. Please, anybody that is opposed to a raw diet do not post as I am not here to be criticized. Thanks You All!
