Hi, you havent given alot of details but I can give you a price range. It all depends on the type of horse and where you live though.
***Keep in mind leasing sometimes the owner gives you all equipment needed and you only pay for use of the horse****but if you are buying one these are some important items:
By the way if you are boarding food is usually included in your price.
1 50lb bag of safechoice is around $15
but board is usually(if cheaper) $250 or higher for a better place it all depends on where you board(it can be up to $500 where I live) board usually includes food(grain and hay), shavings, turn out in pasture, stall, and use of any other supplies like dewormer( for a usually $9 fee depending on place, some do it for free)
One VERY important forgotten fee is Vet (vaccinations and teetth floated)
Shots can be given 1-2 times a year and teeth floated once a year (this can be quite expensive because for teeth they also charge for sedatives) can be up to $300
Farrier comes every 6-8 weeks depending on your horses rate of hoof growth( it is very important to be sure the horse has good sound feet with a thick hoof wall) this can be$25 and up depending on if the horse has shoes or not
Bridle- (new)they can be found for a lucky bargain of $30 online if you find a sale
**Is the horse cob, horse, or oversized
Reins- sometimes come with bridle, but not always- cheapest ive seen is $12
Bit- ordered seperate from bridle, usually around $5
**find out what kind of bit your horse needs**
Saddle-(a used saddle is actually best) you can find good quality for around $500, but if you want a brand name new saddle it can be over $1000
** Keep in mind you need to measure the horse to see if they need a medium, wide, or extra wide tree(most horses are wide)***
I assume you would like me to list some other things you may want/need. :)
Saddle pads- usually around $15 for a nice one but price may vary
Grooming:
you at least want these brushes:
Curry comb- (horses really like the rubber ones) i got mine for $2
Body brush-( some horses are sensitive to this brush) $2-$5 online but can be more
Flick brush- (softer, most horses accept it) $2-$5 but can be more
Face brush-(great for bonding time) usually around $2 or $3
you will also want:
Hoof pick- with brush is great!- for around $2
Towel- can be any towel, even from the dollar store_ $ is up to you, whatever you pay
Face/body/and dock sponges- around $2 each
Showsheen- this is a LIFESAVER when combing- around $12
mane and tail brush- i use a normal brush from walgreens and they love it-$5
Optional:
brushing boots- around $20 and up
polo wraps- under $12
vet wrap- i have seen for $1 @ dover or horseloverz
galloping boots- over $30 but can be worth it
rubber bands(for braiding)- any will do from the dollar store- $1 or more
The list continues:
lead rope- can be under $10, i suggest cotton
halter- rope halter, breakaway, leather, nylon price varies from $10 and higher especially leather gets expensive.
Fly spray-(can make your own or buy some) can be more or less $15 for 32oz
Fly mask or sheet- mask usually around $15-$20 depending on what type and sheets $50 and up
blanket or turn out sheets-$70 or more
(not all horses need blanketing)
Treats-(who cant resist?!) price varies (i can get a 20lb bag for $15)
Ill give you some helpful sites to search for equipment and supplies in order from best to least used by me:
www.horseloverz.com I use this daily!! they will sell lower than any other store and match prices if you find lower!
www.equine.com or www.equinenow.com
www.horseclicks.com
www.doversaddlery.com
Horses dont have to be as expensive as people make it out to be, but plan for an emergency vet call just in case :) Alot for $800 a month (thats including vet, farrien, and supplies you buy) to stay in the safe financial zone.
I own a 6 year old mustang gelding and he is not very expensive at all compared to some.
Good luck! :)
