The most important thing for me now
is someone who is willing to discuss
my horses feet and work out what is best for them.
Not so many years ago, every horse I had was in shoes. That was just the way it was done. Riding horses had to have shoes. After a couple horses who were just never "right", and had constant lameness problems, I figured there had to be a better answer. So, I started researching and reading everything I could find, pro and con, about going with shoes and going barefoot.
I learned there were some really bad farriers out there.
Usually the worse farriers are the ones who will get up in a huff and quit if you even suggest they try something new. Not every single horse is the same, sometimes tried and true methods fail for an individual horse. If a farrier will not discuss what is best for the individual animal I'll pass them by.
