OK.....I have a problem. I know this might sound silly. Here it goes: My lil lady threw up today(only once).....she just seems awfully tired. She has been fine all day long today (running around and playing; etc.). I am just concerned with what is going on with her right now

. I have been holding her and she seems awfully tired

. Also, I know this sounds silly but could this be from "teething"? I don't remember my lil chihuahua doing this

. Please help me!
