Oh no Nala Can you tell if it's coming from her elbow or shoulder? Cody was diagnosed with hip dyspalsia at age 3 and now has arthritis as a result. But I've never heard any cracking; she does limp when she over exercises though. Hopefully it's just a stiff joint or it might be ligament or tendon issue. I have a tendon in my hand that snaps and cracks. Keep us updated Kay. Sending positive thoughts!!! Hugs and slurps from Sandra, Cody and Star
