I am heartbroken as well as dumbfounded. Friday Sophie was fine 100% normal. Saturday morning she also seemed fine. Saturday afternoon she was laying on her bed and did not want to go outside with everyone else which is not unusual for her... she was not crazy about being outside. When it was dinner time she went to her crate to eat, but when I let everyone out of their crates she had not eaten and that is unusual. I picked up her food and decided to offer her food again later... thought maybe her stomach was upset. I was going to work a Kiwanis function @ 5:30. When I returned home @ 10:30 she had passed away. She was only 11 years old and I had her since she was a puppy. She has been so healthy and has always seen her vet regularly, always takes her heartworm meds and her annual shots. I feel awful, if I'd had any indication that she was seriously ill I would have taken her straight to the e-vet. I have two seniors 14 & 13 that are slowing down and I know that I will have to say goodbye to them down the road sooner than I want, but I thought I had many years left with Sophie. She is the only pup that I didn't send to the bridge with me with them when they were old and ill and ready. I have no idea how a happy healthy dog can pass way like this.... such a sad day.
