Jaydee, I wonder what the basis of limiting the height of the child's mount is??
The male rider is clearly too tall for that pony, but he has to ride it because of his age? Some kids grow tall very quickly, we had a ten year old who was very tall--her dad said the doctors say she will top 6 feet when grown.
And I'm very sad for the ponies themselves, as they will likely be sold off when their riders age up. Those ponies must spend only a few years in each home...what is this teaching the children about relationships and loyalty...are they being taught not to get attached to these horses?
That's so sad, for many a young girl, the pony is their best friend and first love...that's like getting rid of the family dog because it no longer matches the new upholstery. Very cold, IMO.
The basis of this is that kids compete with kids, and they ride ponies, size appropriate ponies. You can ride something bigger but then you will compete against adults. A good solid 14.2 hh pony will carry most teenagers, and while the guy in the video might be getting tall, the weight is no issue.
Is it sad for the ponies? Well they go through life having a series of little girls, or boys, to love on them, and they get to teach many kids the joy of riding. I always find it faintly ridiculous frankly to compare selling a horse to gett8ng rid of the dog, your dog is part of your family, lives with you in the house. A horse is an expensive piece of livestock that costs a lot to maintain.
Be realistic here, if a person starts on a suitable school master horse, the odds are he is going to get traded anyway, when the rider secures all the basics and is ready to move up. Unless people do this where are the newcomers to the wonderful world of horses going to find the experienced horses to teach them?
