Have you included supplemental chondroitin sulfate and glucosamine in her diet? They usually work well at healing general wear in the joints. Also salmon oil relieves the inflammation that leads to the pain and lethargy in older dogs.
Thank you so much for your suggestions for my little furry kid. I will ask the vet about these supplements tomorrow. She is taking a canine “Aleve” every 12 hours, (Metacam) and I am open to anything that may help her. Thank you so much!
