Hello. Thanks for the question.
If your dog just ate one tablet, that is not something I'd worry about. It would take a dog this size ~ 450 mg before we started seeing GI ulcer effects. It would take ~ 750 mg before we started seeing renal (kidney) toxicity.
I would not induce vomiting or give anything to her.
I hope this helps, let me know if you have any other questions.
