I just want to have a confirmation since I am really sad at the moment . Yesterday my little sister passed away , she was a year and half . She was a tiny Yorkie , you could call her teacup dog ( she weighted less than 3 lbs). I was sitting on the couch , she always liked to jump on the couch, but this time unfortunately she wanted to jump on me but she couldn’t hold and she fell back on the wood floor and she hit the head. After seeing that she didn’t move for one /two seconds I picked her up. The head was tilted , the head was moving back and for involuntarily. The tongue was sticking out , heart was beating fast . I immediately acknowledged my father who was next to me and didn’t see this happening. My dad tough that she fainted , so we brought her to the sofa . My dad kept her head still all the time .he put an nice block on her head with a blanket . After 10 minutes , nothing was improving . The tongue already turnt blue when we brought the dog to the sofa ( about two minutes after the accident ). Than i called up my brother who actually gave me this dog and has been an owner of Yorkies for a quite long time to tell me what to do . He told me put some sugar on the tongue , make her swallow it . Also we applied cardiac message , but no response . After about 30 minutes from this accident and after trying to reanimate our dog we decided to take to our closest vet . At this point we believed that she had pass away, and it was caused by some brain swelling and internal bleeding . Arriving at the Vet which took us about ten minutes , we rushed and explained everything as fast as possible . After ten minutes waiting the vet gave us the bad news . Now after one day and still shocked I would like to know if there was something I could have done to prevent this . Did we do something wrong ? Did it takes us too long to take her to the vet? If we would have taken her immediately to the Vet instead of waiting 30 minutes , my little friend would have been here now? Thank you for the answer . Also the vet didn’t specify me what caused the death she just confirmed that she passed away and gave me her condolences, is my theory about brain swelling, trauma plausible ?
