Why does my senior dog suddenly limp on hard ground but run on sand?
I'm sorry to hear that Murphy has been limping. Mild weight bearing lameness could be related to a soft tissue injury, cranial cruciate ligament rupture, degenerative joint disease/arthritis, osteosarcoma, among many other issues. I'm glad to hear that Murphy seems comfortable enough to run, but try to avoid allowing him to run until this issue resolves because he could worsen any existing injury. Any time limping is present (to any degree), this indicates a sign of pain. For this reason, I recommend taking Murphy to his vet for an exam, possible x-rays, and possible anti-inflammatory pain medication. Do not give him any over the counter pain medication since none are overly safe for dogs. Until you can get to the vet, try to restrict Murphy's activity to keep him in the kennel and only allow him out for short leash walks to eliminate. I hope that he feels better soon!
