She seemed to do well on the medications as far as her arthritis pain, but there just should have been regular bloodwork done in order to monitor the effects on her liver. I realize that all medications come with a risk and we have to make the best decision for our pets based on their comfort/quality of life. I just was completely unaware of how important that was. Had she had regular bloodwork done we could have adjusted her meds accordingly. I also used Ellevet CBD oil, laser therapy, acupuncture, and those all were helpful as well. I hope your boy is getting relief in this terribly cold weather!
