The pony in the original pic is truly dinky but a couple of the others I am not so sure about their height. The men holding them/standing next to them must be midgets themselves!
Lol ive just acquired one too, he is a mighty 10hh, he is very cute and beautiful, but boy he is a grumpy little monkey, def wouldn't want to put children any where near him!!
There is a definite trend for them but I do have to wonder about the claims some of those men make about their size Lol Lol!
