I have just gotten back into horses after a 20 yrs hiatus. I have a 5 yrs old Percheron and my husband an 18 yrs old foundation QH. When we first got the QH she was very cinchy and would jerk around when saddling. After some time she is now much more relaxed now that she realizes we aren't going to cut her in half with the strap. My Percheron quilding was never over cinched so didn't have that issue. Yesterday a friend went to mount my guilding, I hadn't had the chance to counter weight the other side of the saddle and the saddle rolled. He is a large man... 250 + lbs. My horse never moved and he didn't get hurt. He tried again and mounted with no issues once I had a chance to counter weight him.
The group we ride with are constantly encouraging me to tighten the girths on our horses. I am comfortable with the tightness of the girth. It is snug when I mount and I can often see daylight by the end of a ride. The QH we got from a couple we now ride with. They say one day we'll end up on the side of the horse.
I don't want to cinch any tighter because I worry about long term health problems due to an over tight girth strap (respiratory, muscular, ect). But I also want to be safe.
How tight is too tight? How loose is too loose???
