My daschund just passed away yesterday. I saw no signs of any problems. 2 days ago he was vomiting clear liquid now and again and seemed like he didn't have much energy. He was walking around yesterday and had diarrhea twice. Then he just went under our futon and died. He was 9. Would I have had signs of any illness and what could it have possibly been?
Optional Information:
Age: 9; Male; Breed: daschund
