I spend $600 a month on board, including feed and bedding. Lessons are another $220 a month. His supplements are $160 a month. His farrier is $165 every six weeks. Shots for his arthritis is $200 for 3-4 months. Vet bills are approximately $1000 per year.
Then there is the shopping for tack, blankets, accessories, treats, toys, grooming items, shows, etc...
I spend about 3 hours a night, and 4-5 hours Saturday and Sunday at the barn. But, I have full care board so I don't have to feed, do stalls, or turnout.
I've spent most of my life riding horses. The rest I've just wasted.
