Hi there! My 9 year old Husky slipped and hurt his back left leg back in late September . The vet took x-rays and said it appeared to be a bad sprain, nothing more. He is STILL limping some and having weakness on that that side and it’s been 4 months. We have Novox as prescribed but I am concerned with keeping him on it that long due to side effects. Anyone else have a leg injury that took that long to heal????? thanks in advance
