I'm not sure if I should be concerned about this, but it has happened a few times with Buddy. Sometimes, after he is done drinking out of his water bowl, he will spit up the water. When I go to clean up the mess...it's like clear mucus (no solids come up, even after he has eaten). I don't know if this has happened to anyone else's yorkies? I wonder if this happens as a result of drinking too fast? Anyone have any idea as to why this happens?
Should I be concerned about this?
