Hemp & CBD for Horses

Horse owners are demanding about what goes into their animals — and they should be. At HempMy Pet, our hemp for horses starts with hemp we breed and grow ourselves on our Colorado farm using organic practices, then formulate in-house into a potent, full-spectrum CBD oil. Same seed-to-sale hemp we'd give our own horses, with a third-party lab report to prove what's in the bottle.

What Does "Hemp for Horses" Mean?

"Hemp for horses" covers two very different things, and it's worth knowing which you're buying:

• Hemp seed products (seed, meal, seed oil) — a nutritional feed prized for omega-3, omega-6, omega-9, GLA, protein, and vitamin E. Great for coat, weight, and cool energy, but they contain little to no CBD.
• Full-spectrum hemp extract — the cannabinoid-rich oil that naturally contains CBD, CBG, CBC, and terpenes. This is what owners reach for to support calm, comfort, and recovery.

HempMy Pet's horse formula is full-spectrum hemp extract in a gentle organic olive-oil carrier — so your horse gets real cannabinoids, not just seed nutrition.

How Hemp Works in Your Horse's Body

Horses — like all mammals — have an endocannabinoid system (ECS), a network of receptors that helps regulate mood, comfort, and balance. The cannabinoids in full-spectrum hemp interact with this system to support a horse's natural sense of calm. Because our oil is full-spectrum, the CBD, minor cannabinoids, and terpenes work together — the "entourage effect" — rather than relying on isolated CBD. For background on how CBD from hemp works, see Cornell University's veterinary overview.

Is CBD Good for Horses?

Many owners turn to CBD for horses to support a natural sense of calm and everyday comfort — and unlike most of the category, we have the research to back it up. Our full-spectrum oil delivers CBD alongside CBG, CBC, and terpenes for the entourage effect, rather than isolated CBD. The most common reason owners reach for CBD for horses is calming — around trailering, the farrier, new surroundings, or a generally high-strung horse — and our Tarleton State University study measured exactly that: a reduction in stress during transport.

Is CBD safe for horses? Yes, at appropriate servings. Hemp-derived CBD under 0.3% THC is non-intoxicating and federally legal, and full-spectrum hemp is generally well tolerated — introduce it gradually, keep competition rules in mind (see below), and check with your vet if your horse is on medication. For exact serving guidance by your horse's weight, see the product page.

Backed by University Research

We don't just make claims — we put our hemp to the test. HempMy Pet partnered with Tarleton State University (part of the Texas A&M University System) on a clinical equine CBD study led by Dr. Kimberly Guay, Ph.D., P.A.S., at the university's Equine Center. Using our full-spectrum hemp CBD oil, the research measured CBD's effect on stress during transport and handling — a real-world stressor for horses. Key findings: CBD reduced measures of stress in the horses studied, a higher serving (0.6 mg/kg of body weight) was more effective than a lower one (0.3 mg/kg), and blood concentrations peaked around 4 hours after dosing and were non-detectable by 24 hours.

What Full-Spectrum Hemp Can Support in Horses

Owners most often turn to full-spectrum hemp oil to help with:

• Calm & nerves — trailering, new environments, farrier and vet visits, and high-strung or anxious horses.
• Joint & mobility comfort — everyday support for senior horses, hard-working performance horses, and stiff joints.
• Recovery & everyday wellness — supportive care as part of a daily routine.
• Skin, coat & hoof — the omega fatty acids and GLA naturally present in hemp support a healthy coat and condition.

Hemp, CBD & Competition Rules

This matters and most sellers skip it: cannabidiol (CBD) and other cannabinoids are prohibited substances under FEI and USEF competition rules. If you compete in regulated disciplines, do not give hemp or CBD inside your organization's withdrawal window, and check current rules before a show. Our Tarleton study found CBD was non-detectable in blood by 24 hours, but withdrawal requirements vary — confirm current regulations. For pleasure horses, retired horses, and daily at-home wellness, full-spectrum hemp is a popular choice — just keep competition timing in mind and talk with your veterinarian.

How to Choose Quality Hemp for Horses

Full-Spectrum, Never Isolate

Full-spectrum keeps the natural range of cannabinoids and terpenes intact, which most owners and researchers prefer over isolated CBD. We only make full-spectrum.

Read the COA

Equine hemp is an unregulated space, so third-party lab results matter. A trustworthy brand publishes a Certificate of Analysis confirming cannabinoid content and that the oil is clean — free of pesticides, heavy metals, and solvents — with THC under the legal 0.3% limit. Every HempMy Pet batch is third-party tested.

Organic & Colorado-Grown

Hemp is a phytoremediator — it pulls whatever is in the soil into the plant — so where and how it's grown genuinely matters. We grow our own hemp on our Colorado farm using organic practices and manufacture under human-grade standards, never sourcing from overseas.

How Much CBD Oil to Give a Horse

Horses need far more than dogs given their size, but the rule is the same: start low and go slow, then adjust over a week or two based on how your horse responds. Our Tarleton study used 0.3–0.6 mg of CBD per kg of body weight as a research reference. Because the right amount depends on your horse's weight and what you're supporting, the product page lists serving guidance — and because horses are a large investment, it's worth confirming the amount with your veterinarian, especially if your horse is on other medications.

How to Give Hemp to Your Horse

The easiest way is to top-dress the oil directly onto your horse's regular feed or grain. Olive oil is palatable, so most horses take it without fuss. Consistency matters more than a single large dose — daily use helps the endocannabinoid system find its balance.

Is Hemp Safe and Legal for Horses?

Hemp-derived products containing less than 0.3% THC are federally legal under the 2018 Farm Bill and are non-intoxicating — they will not get your horse "high." Full-spectrum hemp is generally well tolerated. As responsible guidance, introduce it gradually, keep competition rules in mind, and consult your veterinarian before starting, especially for horses on medication or with health conditions.

Frequently Asked Questions

Is hemp good for horses?
Full-spectrum hemp oil is widely used to support calm, joint comfort, and overall wellness in horses, and hemp naturally provides beneficial omega fatty acids. In our Tarleton State University study, CBD reduced measures of stress in horses during transport. Quality matters — look for organic, full-spectrum, third-party-tested products.

Does hemp oil calm horses?
Many owners use full-spectrum hemp oil to support a natural sense of calm around trailering, new environments, and stressful events. Our university research measured reduced stress during transport, and it works with your horse's endocannabinoid system rather than sedating them.

Can I give my horse hemp or CBD before a competition?
No — CBD and cannabinoids are prohibited under FEI and USEF rules. Don't use inside your organization's withdrawal window, and check current regulations before competing. It's better suited to pleasure horses, retired horses, and daily at-home wellness.

How much hemp oil should I give my horse?
