Just to clarify: I said it would take six months before he could enter a regular work regime. Not six months before he could be worked at all. Big difference.
Here is the breakdown of my calculations over a six month time period for a comparable horse with no additional complications:
Board - $300/month (on the low end mind you)
Supplements - $100/month (depends on the horse, can be lower, can be higher)
Farrier - $130/6 weeks (also depends, most of mine went through some sort of rehabbing process with hooves, involving shoes prices vary obviously.)
Vets bills - Including teeth, shots, fecal, blood test etc, sometimes several visits.
$500 (approximation obviously)
Chiropractor - $100/month(haven't had one yet that hasn't needed it, up to the individual as to whether they want to pursue that avenue).
So you're up to just over $4000 for six months. By the time the horse is entering the competitive arena this figure will be much higher. Factor in that the OP hasn't any experience dealing with OTTB's and there is every chance that there will be a trainer involved and I'd say you're going to head over the $5000 mark very quickly. Even if training is free to begin with. Horses that have more serious underlying issues have required more money. It all just depends.
I was in no way discouraging the OP. As I originally said, I really like this horse and would love nothing more than to see him go to a good home and I wish them both the best.
Okay, NOW you are really going to scare hubby!
Board 300 month...includes free choice hay and Strategy
Supplements prob about 100 until his weight is normal, my trainer says she has fattened these guys up for much less though.
Farrier - My farrier charges a 35 flat rate for barefoot.... 75 for shoes. Going to leave him barefoot until farrier or vet says I MUST shoe him. Putting him on the same hoof care as Cinny... Dice has dark hooves too even though he's gray and they look excellent.
Vet, for now the current owner says he is going to take care of the vet appointment tuesday as he gets a discount. This includes workup, shots, coggins and dental check, etc.
My vet charges 50 bucks a visit for Chiro and gives you stretches and the such to do yourself so you can keep chiro visits down to a minimum. This has worked great for Cin.
