I don't mean hold the treat and put the bit in. Keep the treat in your pocket and ask for me to take the bit the second you get the bridle over his ears give him a treat, take it out do it again. 3rd time, don't give the treat. Mix it up somedays first don't give a treat then give next time give a treat. Chance will take the bit with or without a treat because she never knows when she might get a treat when taking the bridle. Its not bribeing nor is it spoiling. Now I can play a game with chance, Ill hold the bit up to her mouth and the second she wants it, pull it further away.. so she will reach for it.. ill just hold it further away its kinda funny because it make her want it more because I don't want her to have it.. :P
If you don't want to use treats for what ever reason cover it in sugar and water, or molasses.
Also some days bridle even when your not going to ride. Bridle - unbridle about 3 times even if not riding.
