shoe no longer in use

Question
Hello sir, how I know when a farrier gets to know that the shoe can be used no longer?????

Answer
Hello ... I'm sorry I can't help you with this. I don't use shoes on horses. I do know, from a horse-owner's pov and my own outlook that the shoes will wear imbalanced if the hooves are trimmed imbalanced and likely will need to be replaced with every new shoeing. They type of shoe is also taken into consideration - the material from which the shoe is made.

Wish I could be more helpful.
