Not really looking for a critique, but i've been working with this horse or 3 years now, and I've noticed n improvement in attitude, stamina, and strength.
Do you think there's a visible difference?
In that first pic. See how's he's standing wth his front feet tucked under his body? That is most likely a sign of heel pain. In that later pic he looks waaay more comfotable on those lower heels. Did you switch farriers along the way?
