My brother said today that he wanted to ride our to older horses. I do not agree with it, but I want to hear what you all think aswell. Jake is a 20 something quarter pony/icelandic cross. He is lame in 1 front foot, grounds to be retired correct?? He was never a good riding horse with his temperment, so my brother would be fighting him the whole time. Elroy is our other horse. He is a 34 yr old ottb. He is underweight, his ribs are covered but his back and and tail bone are promenent. He canters around his pasture sometimes but I still don't think he should have to carry like, 215 lbs(50 lb saddle, plus my bro). What do you all think about riding them? Especially when it is still high 80's, low 90s in the evening.
