Hello & welcome....Don't give up.....There are other choices for pain control......So your Vet sent you away without anything for your dog?
I believe what your Vet is saying is no anti-inflammatory (NSAID) drugs like Rimadyl, Metacam, Previcox, etc. because of the way they are processed & possible side effects
.....However, that does NOT mean that your dog cannot have just pain medication!
My choice would be "tramadol
", but I'm sure there are others....
