I live in a fairly inexpensive part of the "horse world". I'll go ahead and list my expenses for the month of September, so you can see what a bad month for our area looks like.
Hay: $8.00/bale .. Drifter went through 10 bales while on paddock rest..so $80
Teeth Floating: $150
Ranitidine for ulcers: $15
Tums for Ulcers: $6
2 tubes of gastro guard for ulcers: $70
Alfalfa Cubes: $14
Xrays for hocks/stifle: $800
Vet visit for injured stifle: $175
Plus my boarding cost, but you said not to include that, and I have paid for additional things like a new fly mask, a fly sheet, dewormer and thrush buster that I did not include...
That's horrible. I wish I hadn't added it all up like that now. Now my monthly fee is usually no where near this, but a lot of things piled up on us this month. It was one of those months when what CAN go wrong DID go wrong. I think it is important to realize that as a horse owner you WILL have months like this. Drifter usually costs me somewhere around maybe $200/month, but that doesnt mean I should always assume it will be that amount. I would have been SOL if I hadn't been prepared for an emergency such as this month.
I tell people that to budget for a horse plan for an emergency every month...if you have enough to cover that you can safely (stress free) own a horse.
