Fellow dog lovers, I need your support and understanding. My avatar and nickname come from our dog Metani, that we affectionately call "The Chug" or "Chuggie" because she is a pug/chihuahua mix. We rescued her 2.5 years ago (at the age of one). While she can be a royal pain, this dog was completely loyal and always loved to snuggle. Until two days ago she had always been healthy. On Tuesday evening she was running around playing. Suddenly she developed a loose stool and then started to heave and basically couldn't walk. We immediately rushed her to the vet and left her there for what we assumed would be a normal treatment for dehydration and to get medicine. They called us 1/2 hour later and asked us to immediately come back. When we arrived, the vet explained that she went into shock and she quit breathing and her heart stopped. Amazingly, they were able to revive her through CPR. They worked over 3 hours to stablize her, but I could tell that they were still worried. They suggested we rush her to a nearby city to place her at 24 hour emergency vet clinic. We drove her the 45 minutes late Tuesday night, just hoping she would make it there. The vet at the clinic seemed to think she would ultimately be ok, but would need some care to help her recover. We left that night, planning to come back the next day. In the morning they called and said she collapsed again, but could revive her and she died. I couldn't believe what I was hearing. I screamed in disbelief and collapsed on the floor. Since then my husband and I have been crying and trying to come to terms with her death. We paid for an autopsy, but so far there is no obvious cause. How can a robust, healthy 3.5 year old dog just die?! I'm so heartbroken I can hardly take it. We had just euthanized one of our other dogs in July (though he was old and quite sick). We have three other rescue babies with us, but right now I can only think about Chuggie and wanting her back so badly. I wish I could have more time with her. I know that I will continue to treasure our remaining dogs and one day we'll rescue another dog in need. Has anyone else lost their dogs in such a quick manner? I need some words of wisdom or just comfort. Thanks.
