Our pup Ava is doing great--front right leg amputated 8 months ago due to osteosarcoma. She adjusted well especially considering she's 12. Last month we moved into a new apartment and she was slipping and sliding on our new floors and  once or twice her hips splayed out pretty hard and fast. Some symptoms developed: we noticed that she was having a difficult time getting into a sitting position, was shivering in pain, back legs shaking, not wanting to jump on the bed, not wanting to load back legs, tripping over the front paw. Our vet said she injured/pulled her groin. To treat this, we've done two chiropractic adjustments, give her an anti-inflammatory pill daily, and some red light therapy at home. It's been four weeks and she's not really making any progress. Has anyone experienced this? Any treatment recommendations? Thank you for donating your time to help us!
