My dog (Amstaff Labi-hybrid) limped months and I ran from veterinarian to veterinarian, when I finally ended up with a competent veterinarian who finally put a (correct) diagnosis, he advised me Luposan submerge the food and my dog for bring Physiotherpie. My dog had really terrible pain and limped only. Since my little dog Luposan gets (got 5 times physiotherapy) is absolutely hobble and painless and running again all the dogs in the field to :) Certainly the Physiotherapy has much brought Luposan and probably is not the "magic bullet", but I can only say that it has definitely helped and is eagerly eaten by the dog. It smells a little fishy (logically).
