To my knowledge, she was received xrays showing no sign of cancer or arthritis. I asked them to also take her to see another vet for a second opinion, hope that will happen soon. Thanks for the tips and info, definitely good stuff. This dog and his owners are awesome people, so anything that can help is great. I have done 10 hour hikes in the past with this dog, and let me tell you she was covering lots of terrain and never had any issues. At 7 years old, she is too young to slow down or retire from hiking. Thanks again guys.
