My horse has been doing weird things with his mouth lately in playing with the bit more than usual, moving his tongue around a lot. Not really trying to put his tongue over the bit but moving it back and forth in his mouth under the bit (in the foreward/rearward direction). He doesn’t stick his tongue out. He had his teeth done less than 5 months ago, but if anything the issue has gotten worse. He’s always been incredibly mouthy and tends towards wanting to put everything in his mouth, grab his reins, the lead rope, whatever. To ride, he’s gotten much softer in the contact than when I first got him, as he’s started to understand what contact is.
He goes in a HS Dynamic RS Sensogan mouthpiece usually. Most of the time a loose ring, sometimes a short pelham. This seemed to be his preferred mouthpiece after some initial playing around with a french link, slow twist, single joint pelham, and Myler level 2. He liked the Myler mouth ok (sometimes got behind the contact), but the rings pinch the sides of his face, so that wasn’t good. Only thing I’ve changed about the HS is gone up 1/4" because he’s gotten bigger this year.
Thinking of trying the Bombers “happy tongue” mouthpiece. I can only find it in a dee in the US so far. I’d tend to lean towards a full cheek for this horse before a dee given what I’ve tried so far on him. Just looking to help him quiet his mouth/tongue. I’ve thought about the HS Flex Control bit as another option, but it’s 2mm thicker than the pelham and 4mm thicker than the snaffle I have. Not sure that he’d like a thicker bit…he’s got a smaller volume, fleshier mouth. The Bombers comes in the same thickness as the current snaffle (14mm).
