My dog ate Tylenol. Is acetaminophen toxic for a 25lb dog? What to do?
Hi there! According to my drug handbook, although we don't often use acetaminophen in dogs, the dose would be 170mg on the high end for Bella's size. If she truly ate 1/4 of the 500mg tablet it would be about 125mg, and she should be fine.
However, if she ate more than 170mg, overdose is a concern.
If Bella were my patient, I would recommend evaluating some lab work to check her red blood cells and liver enzymes just to be sure there aren't any issues developing. If she did eat more than she should, at least you're covering all of your bases.
I hope you find this answer helpful. Best of luck!
