I went off to the vets today with my 6 years (maybe) old rotti and was told it looks like she has done both her cruciates and has arthritis in one of her front legs. She was given a meloxicam injection and a cartrophen injection, was sent home with meloxicam liquid and we are going back in a week for more cartophen. My question is, is this enough? Too much? Is there something else that can be taken as well or instead? I will not be having surgery performed on her so I just want her to be comfortable and painfree.
