My problem is that our older gelding Sky hates the bit. The second I put it in his mouth he starts chomping at it. Sometimes he even kinda tilts his head tilts inside and down, this is usually only when I put contact on but sometimes he does it just because (I'm very careful my reins are even). He's getting a little better with his chomping and head as I've just been leaving the bit in without getting on. And he is getting better at bringing his head side to side. He just can't get over the bit. Any ideas? It's driving me crazy.
Also I use a loose ring snaffle I've tried thick and thin and none make a difference.
