I had a husky for 6 yrs with same symptoms. Cassie. Took her to the vet, she was depressed and off food. I thought she was bloated due to drinking too much. We thought diabetes maybe. They did a PVC on her and found her belly to be full of blood. The vet suspected a tumour on the spleen also and feared she would have it on her liver. She did. All through her body, she was slowly bleeding to death. I had to have her PTS on the operating table, it was the hardest decision Ive ever had to make and it still haunts me. They said the cancer was through her whole abdomen, never in a million years did I expect to take my dog to the vet and bring her home in an urn. ;) she was only 6 - I had her from the day she was born to the day she died. When I first saw May and saw her belly, Cassie was the first thing that came to mind, I just hope its not as serious and she recovers.
