Hi there, and thank you for posting this question. I think the answer depends on the exact medication and what the margin of safety is for that particular medication. Most likely it would be fine as the weight is so close, but I would want to know what medication it was and then overdose concerns as well as what the margin of safety is. All of this information should be in the package insert. Best of luck and thank you for using Pet Coach.
