I'm not sure of a website for that.
How old is your horse? I know sometimes a horse will come up super lame after being shoed and it sometimes can be cause from placing the nails wronge/ronge fit or something else not done correctly which is the reason you should always use a farrier that has been to school. Another cause for lameness after having your horse shoed can be cause by arthritis or a stiffle in the leg, when the farrier shoes the horse he has to hold the leg up for a long time which can flare up another proublem. Don't auto assume it is from a bad shoe job. Call your farrier and tell him/ her your horse is lame, a good farrier is willing to come back and help you figure out what the cause is and most farriers will work right along side a vet, the two go hand in hand.
