My maltese has a grade 1 in one knee and a grade 3 in the other. She has only had a problem one time when she stumbled over a limb in the yard. It was better within a few weeks after some anti-inflammatory meds. They are just going to recheck her when she comes in (yearly exam) to make sure it's still okay. All of mine end up at the vet more often than once a year for some reason or another and I always have them recheck the legs then too. |
