Is there any heat or swelling in the legs? Is the lameness absolutely in the front legs? Which one and on what surface? How long have they been lame?
Is the horse non weight bearing at the walk coming out of his stall? If so it could be an access.
Is the horse only lame at the trot on a circle? Could be a suspensory.
The heel is very long and collapsed, but we can't see if there's thrush due to the thrush-x already in the hoof.
If we had a video of the lameness, that could help too.
But, all that said, we aren't vets looking at the horse in real life. Horses require vet care just like we require doctors. Unfortunately, that means sometimes having to pay for it when it isn't the best timing. A harsh reality, but that's the price we pay for loving expensive, large, like-to-hurt-themselves animals.
