My 5 year old (today) Silkie Terrie has been vomiting a lot lately. I took her to the animal hospital. They kept her overnight and hydrated her. $800 later, they said her stomach wasn't twisted, but she did have some air/gas in her tummy. She's eating only small amounts of dry food for sensative stomachs. After she throws up foor, she continues to vomit this clear, foamy stuff. Help, please!
