CBD Use in Dogs: Safety, Tolerability, and Dosage
Research shows that cannabidiol (CBD) is generally well tolerated in healthy adult dogs, especially at lower doses. Long-term studies found that daily oral CBD at 5 mg/kg is better tolerated than higher doses like 10 mg/kg, which can cause more frequent soft stools. Both doses, however, lead to increased levels of the liver enzyme alkaline phosphatase (ALP), though this did not indicate liver damage. Still, regular monitoring of liver function is recommended for dogs on chronic CBD therapy .
CBD for Pain, Mobility, and Osteoarthritis in Dogs
Multiple studies support the use of CBD for managing pain and improving mobility in dogs, particularly those with osteoarthritis. Dogs treated with CBD showed reduced pain and increased activity compared to placebo groups. These benefits were observed at doses around 2 mg/kg twice daily, with minimal side effects reported. However, mild increases in liver enzymes were noted, so monitoring is advised Lima2022Yu2021Gamble2018.
When CBD was used alongside nonsteroidal anti-inflammatory drugs (NSAIDs), there was a greater increase in ALP and some increase in ALT, but no clear evidence of liver damage. The combination may offer therapeutic benefits for mobility issues, but more research is needed to confirm long-term safety .
CBD for Epilepsy and Seizure Control
CBD has shown promise in reducing seizure frequency in dogs with refractory epilepsy. In one study, about 43% of dogs experienced a 50% or greater reduction in seizures when treated with a CBD/cannabidiolic acid-rich hemp extract, compared to none in the placebo group. Adverse effects were mild, including somnolence and transient ataxia, and there were no significant changes in bloodwork except for mild ALP increases García2022Potschka2022.
CBD and Canine Behavior
The effects of CBD on canine behavior are less clear. One study found no significant behavioral changes in shelter dogs treated with CBD oil compared to controls, though individual responses varied. Interestingly, dogs receiving CBD showed increased hair cortisol levels, suggesting a possible stress response, but the clinical significance of this finding is uncertain. More research is needed to understand how CBD affects behavior and stress in dogs .
CBD for Stress and Anxiety
Preliminary evidence suggests that CBD may help manage stress in dogs. In a study comparing gel-based and oil-based CBD, both forms were well tolerated and associated with lower post-stress cortisol levels compared to controls. The gel formulation may be particularly promising for stress management, but further investigation is required .
CBD Formulations and Pharmacokinetics in Dogs
CBD is available in various formulations, including oil-based, water-soluble, nanoemulsion, and gel forms. Studies show that all forms reach peak blood levels within three hours of oral administration, but absorption rates and bioavailability can differ. Oil-based and water-soluble forms have similar plasma profiles, while nanoemulsion forms are absorbed more rapidly. These differences may influence the effectiveness and safety of CBD products for dogs .
Conclusion
CBD appears to be generally safe and well tolerated in dogs, especially at lower doses. It shows potential benefits for managing pain, osteoarthritis, and epilepsy, with mild and manageable side effects. However, increases in liver enzymes are common, so regular monitoring is important. The effects of CBD on behavior and stress are less certain and require more research. Differences in formulation can affect absorption and efficacy, highlighting the need for standardized dosing and high-quality products. More large-scale, controlled studies are needed to fully understand the therapeutic potential and safety of CBD use in dogs.
