The state of the evidence
Veterinary research on CBD in dogs is young but no longer thin. Several controlled studies on osteoarthritis have reported improvements in owner-rated comfort and activity over several weeks of daily dosing, with generally good tolerability. Sample sizes are small and the field needs replication, so treat the findings as encouraging rather than settled.
How the math usually works
Dosing in the literature is typically expressed per kilogram of body weight, given twice daily. That makes concentration, not bottle size, the number that matters — a pet tincture is formulated to make small doses measurable, which is precisely why human tinctures are a poor substitute.
What to watch for
- Drowsiness or unsteadiness, especially in the first week
- Soft stool or reduced appetite
- Any interaction with existing medications, particularly NSAIDs and seizure drugs
Talk to your veterinarian first
Elevated liver enzyme values have shown up in some studies, which is one reason baseline bloodwork and a conversation with your vet matter more for an older dog than for a young one. Bring the product's COA to the appointment.
