I ride my coming 5 year old quarter horse in a loose ring snaffle, 5". He had a few months off in the winter and we just started riding again, but now the bit I used all last summer without issue is rubbing at the corners of his mouth causing callouses (spelling) I tried another bit, 5" D ring and it does the same thing. I was thinking about putting bit guards on, but I don't know if there is enough room.
Do you think the rubbing is caused because the bit is too small for him? Or because of the kind of bit it is? Should I try a french link to see if that fits him better, or just move up to a 5 1/2?
If I go 5 1/2 and it is too loose, will bit guards work then?
Any suggestions would be helpful! I have a feeling I'm going to spend a bit of money on different bits but a starting point would be good.
I'm going to try to borrow some bits from my friend, but right now isn't a good time to ask. She may have to put her TB down due to an injury :(
