Well, I myself own a five year old cavachon (Still looks like a pup. :) ), but he has never snapped. Not to jump too quickly to conclusions, but I suggest having him neutered. It may be the feel of male dominance within him that is trying to come out. Now it can happen one of two ways, you can find him a mate through a breeding program, or you will have to cut off the sack. My dog never mated, nor has he snapped, but for safety reasons, we did it anyways. He is much more calm now, but still playful and loving. And if my solution didn't help. Try another way. Maybe taking him to a training center. But I think putting dogs down is never the answer unless the dog is in sign of extreme pain, mainly death, or if he kills someone. Even then, I don't suggest it. But maybe you will find this helps. I'm not an expert, (Only 13 ^.^) but I sure know some stuff about dogs.
