Why A Horse Acts Girthy When They Are Not Lame
Girthiness is usually a reaction, not a personality trait. Horses remember how things feel. If the girth, saddle, or rider weight has hurt them in the past, they often start to protest at the first sign the process is starting again, even if they can still move sound.
That protest can come from sore muscles, a sensitive ribcage, ulcers, saddle fit, or simple anxiety about what comes next. Sorting those out is how you help your horse feel safer and calmer.
