Rae, I would be very careful giving her Meloxicam in case it is her tummy bothering her and not her back. It is an NSAID. I got a stern lecture at the e-vet about giving Sofie NSAID for pain. Apparently it can make nausea and vomiting worse, as well as make stomach pain worse. It also can suppress the appetite.
