Just thought I'd let you guys know that my 4yr old german shepherd died yesterday unexpectedly. I was at work but my wife called me twice to let me know he had been throwing up and hiding in weird places outside. It was a typical busy monday at work and my dog had been known to get into stuff that makes him sick so i just told her to make sure he has water & food and it would pass. About 3:00 i got the call from my wife saying he was gone. After confirming with my vet tech sister, she told me to look up "canine bloat" so i googled it. Every single one of the symptoms fit my dog exactly. I just wanted to post this link because I had never heard of this problem with bigger dogs. If I can help one of you to possibly see these symptoms early, there usually is a good chance of survival with surgery. Thanks and so long bud! Canine Bloat: Links
