Don't like thinking about this!
DIY Livery £20 a week(this includes yard owner bringing him in at 2 so he can have hay and first feed as he's been ill so needs extra feed right now. )
Feed at the moment is around £20 a week due to his illness, previously I was spending approx £5 per week.
Bedding £5 a month (because he's not stable kept only comes in for feeding), but I do use rubber matting so initial outlay for that was approx £100.
Shoeing £55 every 6-8 weeks- assuming he doesn't throw a shoe which is an extra £15.
Insurance £16 a month.
Worming £50 a year approx.
Vaccination £50 a year.
Vet so far this year has cost me approx £100 so not claimed off insurance due to excess.
You have to remember event or show fees. Transport costs.
Tack..well so far this year I've had to buy 2 new saddles, 2 new saddle pads, stirrup leathers, reins, boots for the horse and stirrups. Approx £1000
Boots for myself £100+. New riding hat as I had a fall £70. Body protector £80.
And that's just what I can remember, cos I'm sure I've spent MUCH more than that already this year!!
Always makes me laugh when people say you must be rich to own a horse....it's because I own a horse I'm NOT rich!!!

But I wouldn't be without him and he's worth every single penny!
