I have a female dog, collie-shepherd mix, which had a nasty hip/thigh injury when she was 6 month old, abused. Lizzy had surgery and it took her 6 more months to recover with rehab and water therapy. She will always have hip problems but walks almost normally. When I walk her I sometimes hear a noise like bone shifting which scares me as she is so young. The vet said put her on medicine right away. And so I did as I thought otherwise it would not help her when she is older. And the bone shifting stopped thanks to Liquid Vet. Thank you.
