My puppy was groggy after spay surgery and then died. What happened?

Pet's info: Dog | Italian Greyhound | Female | spayed | 9 months and 17 days old

Hi, our 9 month old Italian Greyhound puppy was spayed last Thursday. Everything went well, except she was constantly groggy after her surgery (she never perked up). She would cry during the night and our vet said she was just being a sook. She was eating and going to the toilet fine. Her wound looked clean. She passed away on the following Friday (8days later). I woke that morning, she looked exhausted, vomited, pooed and wee’d herself. We rushed her to a vet but she passed away on arrival

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am SO sorry! What a horrible situation! I wonder if Luna had an underlying condition where she was unable to metabolize drugs and anesthesia. She could have had a genetic liver shunt (porto-systemic shunt) or an MDR reception issue. This is a very abnormal response to a spay and I am very sorry that you went though this and poor Luna. Did you request a necropsy with your Vet to see if anything could be found? Again I am very sorry about your loss and I hope this helped.
