I've never had a dog but I have had quite a few animals with untimely deaths. A guinea pig who got Cancer, A cat which got Diabetes and in the end had to be put down, a mouse who had a heart attack and another who kept scratching it's face to the points that it had no ear and it's face was just scabs. We had him put down. Sorry to hear about your loss. Look it up on the internet or speak to your local vet about it.
