How often do you have your horse adjusted?
My farrier use to do my chiro work too, and he's just check how when he came, but I no longer use him. I found a new chiro but don't know how often my horses should see her...
I am a Chiropractor. Animals are generally like kids they don't need it as often and respond quicker. Find a good chiropractor and do what he says. Some horses need it a few times a year, others need it once a month, depends on how your horse carries himself and what you do with your horse.
When needed.. I use a osteopathic vet We do lots of different stretches etc that she recommends and has really made a difference. I also use a back on track blanket etc..
