8 /12 yr old male sheltie with bad gall bladder, osteo arthritis in his hips and shoulders. Cannot take many of the pain meds due to stomach/gall bladder so been on prednisone for a few months. This obviously is not good for his liver but how else to keep him comfortable? Vet has suggested Laser Therapy, any news on this working? Or any suggestions for anything else to do? He was diagnosed with the arthritis at 6 months after X-rays. I need him to be comfortable and as healthy as possible.
