Our 14+ year old Shepherd mix has osteoarthritis in his hips and we've tried Deramaxx, Rimadyl and Vetprofen. While I can't speak bad of them, Previcox has provided more relief than the others. Instead of walking like his back legs are made of 2x4's, he actually has a bit of flexibility in the knee. Also, he is not panting like he used to (sign of pain) and also again enjoys rolling up onto his back and wiggling in the grass like he used too!
I used this for my dog when he was having dental work done, and now I'm using it again because he's got some arthritis in his hips that the vet and I are trying to get under control. It seems to work really well.
I have tried other pain relievers on my dog Bear but Previcox is the best! The other ones didn't work as well at all, he still had pain or they had bad side effects. But Previcox works so well I only have to give it to him every third day! If anyone is looking for the best for their dogs choose this one!
