I am new to the pony breeds! I am considering buying a pony for my 2 boys ages 3 and 5. I have had several people to tell me not to buy a shetland because they are mean. I would like one that is kid safe. Registered would be nice as well. I am trying to get them into showing. They have been riding horses since they were born. They have only been walking my 3 year old filly. Robbie the 5 year old tries to get cutter to trot but she won't for him. I always stay in the round pen with them but am wanting something that they can go ride and I know that the pony is going to take care of them without me fearing that they are going to fall off of Cutter. Cutter is 15.1 hands tall a pretty good distance to the ground when you are only 3 feet tall. Please any suggestions would be great. I am willing to pay as high as $1,500.00 for one that is good with kids and is well trained like to back up but more importantly the whoa is very well established.
