From your descriptions of
vomiting vs regurgitation, it sounds more like regurgitation. Since she had her patella tendon repaired as a puppy, and then spayed, she has had esophagus problems. And this morning she is making noises in her throat similiar to choking or trying to cough something up. But there is nothing stuck in her throat, and I don't give her bones. Last night it was just some very small pieces of baked chicken.
