I have an 11 year old silver sable sweet girl. We have a huge yard that she runs with her 9 year old puppy boy. She always stays active and in good spirits. We have never had health issues with her except heart worms that’s shes had treatment for and her hips are a little stiff when she gets up from sitting. This morning she was found dead by her food bowl with blood coming from her mouth. We have no clue what could have happened or if there is a genetic trait that causes sudden death. If there is ANY information, I’d be happy to see anything that others know.
