There are two things you need to take into account. Firstly, what makes you conclude that your horse doesn’t like the bit? A lot of difficulties in the connection can be traced back to, for example, the saddle, the seat of the rider, or the natural crookedness of the horse.
A young horse is also not used to having a bit in his mouth so he needs time to accept the bit. The time that a horse needs to accept the bit, and keep his mouth closed and quiet with the bit in, varies from horse to horse.
Finding the most suitable bit for any horse requires time and effort. The double-jointed eggbutt snaffle is, as pointed out, one of the most commonly used bits to start a young horse with. The double-joint spreads the pressure more equally in the horse’s mouth. The fixed bit rings enable to bit to find a steady position in the horse’s mouth. However, there is no hard and fast rule.
When trying a bit, take the following into consideration:
The best way to find the right bit is to try several and pay close attention to your horse’s response. Make sure you give your horse sufficient time to adjust to the bit. If the bit is correctly sized, and your horse has a closed mouth and does not give an extreme reaction to the bit, then try the bit for a week or two.
