How big should a bit be for a 17h TB?
I bought a new horse just this week and I need to buy a bit that will fit him. It's going to be a snaffle bit. I tried contacting his owner about the size, but she won't respond. And, yes, I know you need to measure the horse's mouth in order to be accurate enough, but I want to make sure that it will come in by the time he gets here so I don't have to wait 1 week (or more) before I can ride him.
The bit that I'm looking at offers the biggest size at 5 1/2 inches. Will that be big enough?
