i noticed our 1/4 horse X Luna was lame today when we went down to worm her, it seemed to be her back feet at first but then i noticed her favouring her front...she couldn't rest, etc. i thought maybe colic, but no...normal poos, normal behaviour, active gut. founder? no lines, stance, etc. although i did notice her front left foot looked very heeley and tall, but her other one didn't. we had a thoroughbred mare in the past who had a clubfoot and was lame when we got her, ... we didn't notice our old horses lameness at the time (our old thoroughbred was named smoothie) because she was very underweight, Luna was underweight as well. i'm not certain Luna has a clubfoot, but her one foot looks tall and rounded like a clubfoot would, and she has a normal heel and shape on the other one. she didn't present as clubfooty at her last trimming but the pasture wasn't as good then, and she wasn't get as much nutrients from the pasture. she also seems a bit lethargic but i think if the clubfoot is bothering her and making her lame than that would be much of a cause of her lethargy, plus she hasnt let me put fly spray on her (WE DiD iT TODAYYYY, FiNALLY SHE LET ME) and she's been bugged NON STOP (excuse the pun) by flies, skeeters, horse flies, etc. so her lethargy could be a lack of sleep as well. any thoughts? Essentially, my actual question is .. does a clubfoot if left untreated or unnoticed create a considerable amount of pain in the joints? thus rendering the horse lame/stiff.
