You can use Jump For JOYnts as prevention in theses case: Each animal is different, and in turn, so are their individual needs. For dog breeds out of puppy stage, we recommend to our clients to give one dose twice a day for two days and then once per month. If your dog does agility and has a particularly strenuous run you can give a dose right after. If your dog is middle age and is an agility freak (so focused that they feel no pain when they maybe should overextend themselves regularly) it is a great idea to do the JFJ twice a day for two days once a month. If your dog has EVER had a limb injury but has no residual problem it is helpful to do J4J twice a day for 2 days and repeat that once every 4 months.
