Q. My 15 year old female red aussi Shepherdhas little strength in her back legs. Sometimes she just wont move. Although she still wags her tail and eats

A. The weakness in your dog's back legs could be related to arthritis, which is often the case in older animals. I would have your veterinarian evaluate to determine it is truly arthritis and not an underlying soft tissue injury or skeletal issue, such as a fracture. In many older animals with arthritis glucosamine chondroitin is recommended. You veterinarian may also prescribe a non-steroidal anti-inflammatory, such as Rimadyl or pain medication such as Tramadol.
