Thanks everyone. It was horrible, the groomer rushed her to the vet, they resesitated her three times, but they couldn't stabilize her, they were trying to get her stabilized so they could get her to a cardiologist but it just wasn't meant to be. She kept vomiting up blood. I think she was bleeding into her stomach. It was all really violent. The vet thinks she had a tear in her heart. I don't know how this could have happened so quickley. She was just playing with Paco on Saturday, running around the back yard. My poor daughter is just heart broken, poor thing she has been through so much in the past year and this was just the last straw.
