im sorry but thats cruelty.
your daughter is quite heavy for her height. if she is a young adult i think if you were to check the bmi nhs calculator it would say she is overweight. i dont think ypu can use the calculator for kids though.
it could be that she is a good little rider and not thumping up and down on that poor pony’s back so not as bad as a beginner of that weight, but she is still too heavy for that pony.
i had a 13.1 connemara and rode bareback at 10 stone (the saddle would have taken me up another stone which i felt was not fair on him) so im not some kind of person whose lost touch with reality.
i knew i was a little too heavy for him and my legs dangled down past his belly so i checked with our old school sensible vet who knew him for a decade said he should be ok but will tell you when he’s had enough. I didn’t do much and he didn’t complain - until one day he just refused to canter (he never did that) and i thought fair enough and did not ride him again.
Now i dont know if you have checked with your vet but i cannot help but think your child is far far too heavy for that poor pony and should not be on it.
my 6 foot ex-boyfriend weighed 11 stone. id never have put him in a 12.2hh pony. Not because of his legs dangling round the pony’s legs but because he’s too heavy for it. 11 stone is not light.
please stop your heavy child riding a tiny pony.
at the very least you will damage its back and it will cost you in vet bills. i cannot understand why you think that’s ok.
