The short answer is yes—DK Horse is legal for use in Wisconsin today, but the regulatory framework shifted dramatically on July 1 2026 when the state reclassified all hemp‑derived equine supplements under the new “Equine Wellness Act.” That change tightened labeling rules, set a 0.3 percent THC limit, and required registration with the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP). Prior to 2026, DK Horse operated under a loophole that treated it as a livestock feed ingredient, allowing broader claims and weaker oversight.
Legal Status in Wisconsin
Under Wisconsin Statutes § 147.65, hemp‑derived products containing less than 0.3 percent Δ⁹‑tetrahydrocannabinol (THC) are exempt from the Controlled Substances Act. DK Horse, a cannabidiol (CBD) supplement formulated for performance and joint health in horses, falls squarely within that exemption when its THC content is verified by an independent laboratory. The DATCP has issued a compliance notice (2024) confirming that any product meeting the 0.3 percent threshold may be sold without a veterinary prescription, provided the label includes a batch number, manufacturer information, and a statement that the product is “not for human consumption.”
What Changed in 2026
The Equine Wellness Act, enacted by the Wisconsin Legislature in early 2026, introduced three key amendments:
- Mandatory Registration – All CBD‑based equine products must be registered with DATCP before distribution. Registration requires submission of a Certificate of Analysis (COA) confirming THC levels.
- Standardized Labeling – Labels must list the exact cannabinoid profile, dosage instructions, and a warning that the product should be kept out of reach of children and other animals.
- Advertising Restrictions – Health claims are limited to “supports joint comfort” and “promotes calm demeanor.” Any assertion of disease treatment or cure is prohibited without FDA approval.
These provisions were designed to close the gap that previously allowed manufacturers to market unverified benefits, and they align Wisconsin with the federal Farm Bill’s hemp provisions while adding state‑specific consumer safeguards.
Implications for Owners and Veterinarians
For horse owners, the 2026 reforms mean greater transparency but also a need for vigilance. A COA must accompany every purchase, and products lacking proper registration can be seized by DATCP. Veterinarians can now advise clients with confidence that a registered DK Horse product complies with state law, but they must refrain from prescribing it for any condition not listed on the label.
For veterinarians, the act also creates a reporting pathway for adverse events. Any suspected side effect—such as lethargy, loss of appetite, or signs of intoxication—must be submitted to DATCP within 30 days, enabling the agency to monitor safety trends.
Compliance Tips
- Verify the COA – Request the most recent analysis and confirm the THC level is ≤ 0.3 percent.
- Check Registration – Look up the product on DATCP’s online registry; unregistered items are illegal.
- Read the Label – Ensure dosage instructions are clear and that no prohibited health claims appear.
- Document Use – Keep a log of product batch numbers and administration dates; this aids traceability if an issue arises.
- Stay Informed – Legislative updates are posted quarterly by DATCP; subscribing to their newsletter helps you remain compliant.
FAQs
Is DK Horse considered a controlled substance in Wisconsin?
No. Because its THC content is below the 0.3 percent threshold and it is registered under the Equine Wellness Act, DK Horse is exempt from the state’s controlled substance schedule.
Can a veterinarian prescribe DK Horse for arthritis in a horse?
Veterinarians may recommend a registered DK Horse product for “joint comfort,” but they cannot prescribe it as a treatment for arthritis unless the label explicitly includes that indication and the product has FDA approval.
What happens if a DK Horse product exceeds the THC limit?
Products found to contain more than 0.3 percent THC are classified as a Schedule I substance and are subject to seizure, fines, and potential criminal prosecution under Wisconsin Statutes § 940.06.
Are there age restrictions for purchasing DK Horse?
There is no age restriction for buying DK Horse, but the label must caution that the product be kept out of reach of children and other animals.
How can I confirm that a DK Horse product is properly registered?
Visit the DATCP’s Equine CBD Registry website and search by product name or manufacturer. The registration number, COA date, and expiration will be listed if the product is compliant.
