Valentine is starting to fall on her remaining front leg.  She is also pausing around some of her ordinary daily habits like hopping 3 inches up onto her dog bed or 6 inches up onto our bed which sits on the floor.  Till now she has never had a problem with these tasks, she is also tentative when hopping up or down the stairs to go outside.  She is two+ years post-amp and has done so well, till now. She was 10 years old on Valentine's Day, her name-day. Also her leg seems to swivel inwards and her wrist looks like it is stretching and collapsing.  We have a thera-paw wrist support brace which we hope helps and a harness which we use to help her when needed. She sees a chiropractor and acupuncturist regularly. Her weight is good.  We tried a local physical therapist a while back but it didn't work out so we stopped.  She has had a fantastic post-amp quality of life, she patrols and guards the yard and herds our other dog, a husky.  We are wondering whether she hurt herself somehow or her front leg is just wearing down.  We have a regular vet appointment scheduled for Tuesday.  We are thinking it might be time to start adequan shots or steroid shots.  Please share any suggestions you have for us.  Thank you for your comments.
