I have a question about my Lab that is VERY sore due to lack of exercise. We went on a 3 1/2 mile walk today and she is extremely sore. I not in the business of playing Doctor, I would like to help her with some Aspirin / Ibuprofen. I use to give my other lab medication in the past, but lost my "dosage" chart. Can anyone help. She is roughly 60 LBS. Thank you
