CBD for horses: our university research and other published studies
The university tissue studies explain where cannabinoids may act in horses. Other researchers tested different preparations, with positive, mixed and no-benefit findings. None of these publications tested Pet Routine for Horses, which is for external use only.
Our university research partnership
Our horse research at the University of Bologna
Formula Swiss has funded research by Professor Roberto Chiocchetti's team at the University of Bologna into how cannabinoids could act in horses. The university's record lists a 2019–2021 Formula Swiss-funded project on CBD receptors in the horse's gut and spinal nerve ganglia, and three of the studies below name Formula Swiss as their funder. These are laboratory studies of horse tissue. They show where cannabinoids may act in the body, but they did not test a CBD product in living horses or establish a dose.

Questions about our CBD oil for horses
What is in Pet Routine for Horses?
Each 30 ml bottle contains 3,000 mg CBD (10%) and 300 mg CBG (1%) in MCT carrier oil, with a 0% THC specification. That is 3,300 mg total cannabinoids. See the ingredients table and laboratory report for details.
Is this the 2026 formula?
Yes. This is our 2026 Pet Routine for Horses formula. Formula Swiss has produced CBD products in Switzerland since 2013, bringing more than 10 years of CBD experience to the range.
How do I use Pet Routine for Horses?
Shake the bottle well before use and apply the drops directly to your horse's skin as directed on the label. The product is for external use only.
How many drops should I use for my horse?
Follow the amount and directions on the label, and ask your vet if you are unsure.
Can I use it alongside my horse’s medicines?
Ask your vet before use, especially if your horse takes medicines or has a health condition. CBD can interact with medicines. Do not stop or change prescribed treatment. Do not use in pregnant or breeding animals, and stop use if an adverse reaction occurs.
Is Pet Routine for Horses a registered medicine?
No. Pet Routine for Horses is not a registered veterinary medicine and is not intended to diagnose, treat, cure or prevent disease. It is not a substitute for veterinary care or prescribed medication.
Did the university studies test this horse oil?
No. The University of Bologna studies mapped cannabinoid receptors in horse tissues. Three of the four papers in our university section acknowledge Formula Swiss funding. Other research used different preparations. None of these publications tested Pet Routine for Horses.
Can I use CBD if my horse competes?
Do not assume that 0% THC makes a CBD product competition-safe. CBD and other cannabinoids may be prohibited under the rules that apply to your horse. Check the current rules with your governing body and vet before use. We do not give a competition withdrawal interval.
