We have a 4 year old American miniature x miniature shetland who gets fat on fresh air and as she has already had laminitis before we took her on, its a nightmare trying to keep her weight down and getting turned out is down to a minimum because even at this time of year on limited grass she balloons.
We are thinking of breaking her to drive just to give her something to do rather than standing in the yard.
She is only 30" so probably wont be able to do much but even if we just drive her up and down the drive twice she will have done a mile 
anyone else driven miniatures if so what size where they
