I ride in Ontario Canada!
I can’t give you an accurate price because it varies on the vet/farrier/barn.
It my barn, inside board is about 350 a month, including turn out, grain, hay, putting on blankets, fly masks, fly spray, shavings, water etc.
Outside its about 100. They come inside if its going to rain hard all night or if there is a storm and they get unlimited hay, water and grass access.
The farrier, for a reset of all 4 shoes is about 150. For a trim its about 70 or around that. (I don’t have a horse that doesn’t wear shoes so I don’t know the exact pricing)
Chiropractor comes every once and a while and its about 40 dollars per visit.
Then lessons for a group are 35, and private are 40
And a decent horse hunter/jumper horse around here goes for about 7,000 +
And then on top of that are the fees for all of your tack, I plan on showing in the A’s so I had to buy all good quality saddles, briddles, show equipment etc. So my bill came to around 3,000 dollers.
Its not cheap owning a horse.
