sounds like she has damaged her cruciate ligament! took my 7 yr old lab to have hers repaired at a cost of £2500 we had insurance but only basically covered xrays and orthopeadic vet consultation! when we took her on the morning of op the vet said it was both her knees needed surgery and her hip! surgery recovery is at least 3 months! I may sound cruel but i really dont want to put her through 3 lots of extensive surgery not to mention a cost of £8000 which i simply dont have! i love my dog but i really dont think i can put her through it! at the moment it is only a partial tear and can be managed with pain meds but if it tears completely and she goes off one or both of her legs she will then be in pain and we will simply have to euthanase! this is breaking my heart i am agonising over it all i havn't slept properly for weeks! i will never ever get another pet because of all this!!!
Welcome...If she can't go UP, it's either her knees or hips...If she can't go DOWN, it's her back! Your Vet should have offered you a trial of Anti-inflammatories to see if she improves or not.....A good joint supplement should be included in her routine, also....
I also would make sure it's not her eyesight.....Karla
