How does your donation help?
Donating to a horse rescue is a powerful way to make a real difference in the lives of equines who have been neglected, abused, or simply left without a safe home. Your support helps provide essential care—such as veterinary treatment, farrier visits, nutritious feed, and rehabilitation—to horses in need. Every contribution, no matter the size, goes directly toward giving these animals a second chance at life, whether that means finding them a loving forever home or providing lifelong sanctuary. By donating, you become part of their journey from hardship to healing, ensuring they receive the compassion, dignity, and care they deserve.
How is your donation used?
The donations you give to Happy Tails Haven Horse Rescue and Sanctuary make an incredible difference—and here’s exactly how they help care for our horses.
Hay
Hay is one of our largest ongoing expenses. A single 1,500–1,900 lb round bale costs between $110 and $165, and we need 12 bales every month at $165 each—that’s $1,980 monthly just to keep our rescue and sanctuary horses fed!
Special Feed
Ten of our sanctuary horses require carefully tailored diets to meet their unique needs. Their feed may include senior feed, timothy pellets, Square Meal Biscuits—or a mix of all three—along with important supplements and medications like Cool Calories, Heiro, Previcox, and Prascend.
-
A 50 lb bag of senior feed averages $26.99
-
A 50 lb bag of timothy pellets averages $22.99
-
We use about one bag of each per day, which adds up to $349.92 per week, $1,049.76 per month, and a staggering $18,195.84 per year—not even counting supplements or biscuits (which average $15.99 per bag)!
And the extras add up too:
-
Cool Calories – $31.34 (8 lb bag)
-
Heiro – $58.95 (monthly)
-
Previcox – $51.90 (60 tablets)
-
Prascend – $420.09 (160 tablets)
Thanks to your generosity, our senior horses receive the proper nutrition and medications they need to live out their golden years healthy and happy.
Here’s the simple truth: For about the cost of one nice meal out, you can feed one of our horses for a whole day. Please consider donating or sponsoring a senior horse today—you’ll be giving more than food, you’ll be giving them comfort, care, and love.
