Dambit... I've had two puppies over the years that died like that also... One that I still feel guilty about but I know there wasn't chit I could do. Real Sorry for your loss... What really suks is no matter what kinda dog you'll ever have, you'll most likely see it pass away, very sad but its a reality that we all go through. My kristin passed away about 4 years ago, luved that chow, great dog with a big heart. I have two fiesty azz pugs now Bert who is 11 and Lyla who is now about 5 years old... Bert's getting old but still acts like a puppy but I know someday I'm going to lose my lil friend, it will be a sad day indeed...
