Sorry! The information you gave me is very limited. Could you gice me a DV file and even radiographs, otherwise, I cann't give you the right recommendation. Also, I need the dog's basic information such as breed, age, gender, weight condition. Thank you.
Sorry again! Due to the very limited information, I still can not give you the right recommendation. Lack of strength is a very subjective describtion. There are too many possibilities. To take a picture of the radiographs and email it to me. Use a digital V8 to take a video file on the problem walking will be very helpful to me.
