help

i need some advice. I have a 2 year old teacup chihuahua (male) who my husband thinks he got bit by some fire ants today. He is not red or anything, but he can't be still. He is going around in circles and hiding.
Any advice on how to make him comfortable. We gave him a bath and that seemed to help temporarily

Can you see any bite marks on the skin?

Chi's are nervous by nature and do you think this has just made him sensitive and upset? The initial trauma is over but maybe he has some post trauma aggitation? Not sure but it's possible.

Occupy the dog with something to do, play toy or ball...or some ice to chew on or a favourite treat! Something positive and happy could direct his attention from what was bothering him.

Showing any other symptoms?
