Make sure that your horse is fit enough for the required work. Always start low and start to build up the work load over time. It’s also good to ensure that you have your horses feet and teeth done regularly. As well as having a qualified physio to check them every now and then. Horses do a lot for us, so it’s always good to make sure we give them the best care that we can :)
If you think your horse is sore, definitely get the vet out to do an exam. Depending on what the problem is you can try massage, chiropractic, stretching and linemints and poultices.
Well that depends on a lot of things. Age, confirmation, hooves, ect. Definitely get a vet out to make sure he isn’t developing ringbone, navicular or any other leg/ joint/ back issue
