5/15 EDIT: I purchased a Verbindend loose ring and universal and he loves it. The loose ring is great for hack rides and the universal is perfect to the jumps. I had purchased a myler as well but decided to return it before trying it since the verbindend was so nice. Thanks for the recommendations!
On a recent exam of my horse’s mouth I found some concerning sores and redness.
Both corners of his mouth, inside and not visible unless I pull out his lip and look inside his mouth, have small sores. They’re the same on both sides.
He also has some red marks that look like bruising on his tongue, approx 1/4 of the way up from his front teeth to the end of his visible tongue. The left looks worse than the right side.
So I realized his tongue is very big, and it seems like there is significantly less room for a bit than a normal horse. He also has very big lips. I’ve tried to do some research on bits based on mouth anatomy but haven’t had too much luck.
He tends to canter with his mouth open, sometimes he is heavy and sits in my hand, and frequently over fences he grabs the bit and pulls. I keep thinking I need more bit but he’s sensitive so too much bit and we aren’t moving anywhere, but now I think I just need the right fit. I’m wondering now if I find a bit that fits properly these things might stop.
His teeth were done by our vet 2 months ago, nothing was of concern then. These have developed over the past 2 months. The only new thing is we ride in a happy mouth 2 ring with rubber bit guards. It does not have any sharp chew marks in it.
