Pet Hemp Studies

Based on a review of available scientific literature, here is a curated list of key peer-reviewed studies and reviews focusing on the benefits of CBD for wellness in dogs and cats. These cover areas like pain management, anxiety reduction, inflammation, osteoarthritis, epilepsy, and overall stress relief. I've prioritized recent publications (up to 2025) from reputable sources like PubMed, PMC, and veterinary journals. Each entry includes the title, authors, publication year, key findings, and a link where available.

​

  • Scientific Validation of Cannabidiol for Management of Dog and Cat Diseases Authors: Corsato Alvarenga I, Panickar KS, Hess H, McGrath S Year: 2023 Key Findings: Reviews CBD's mechanisms (modulating receptors like CB1/CB2), pharmacokinetics, safety (well-tolerated with few side effects at physiological doses), and efficacy. In dogs, CBD improved symptoms of osteoarthritis (reduced pain), pruritus (itching), and epilepsy (seizure control). Limited cat data suggests similar potential, but more studies needed for anxiety and aggression in both species. Link: https://pubmed.ncbi.nlm.nih.gov/36790884/

​

  • Daily Dosing of Cannabidiol (CBD) Demonstrates a Positive Effect on Measures of Stress in Dogs During Repeated Exposure to Car Travel Authors: Hunt ABG, Flint HE, Logan DW, King T Year: 2024 Key Findings: Over 45 days, daily CBD (4 mg/kg) reduced aggressive behaviors in shelter dogs and alleviated stress during car travel, suggesting benefits for anxiety and behavioral wellness.

​

  • A Single Dose of Cannabidiol (CBD) Positively Influences Measures of Stress in Dogs During Separation and Car Travel Authors: Hunt ABG, Flint HE, Logan DW, King T Year: 2023 Key Findings: A single dose of CBD reduced stress indicators (e.g., cortisol levels, whining) in dogs during separation anxiety and travel, but evidence for long-term anxiety relief remains limited. No cat data. Link: https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2023.1112604/full

​

  • Tolerability of Long-Term Cannabidiol Supplementation to Healthy Adult Dogs Authors: Bradley JM, Atamanchuk S, Bienzle D Year: 2023 Key Findings: Long-term (36 weeks) CBD at 5-10 mg/kg/day was well-tolerated in healthy dogs, with no hepatic damage but possible ALP elevation. Supports use for chronic conditions like inflammation or pain. Link: https://pmc.ncbi.nlm.nih.gov/articles/PMC10800185/

​

  • Effect of Cannabidiol (CBD) on Canine Inflammatory Response: An Ex Vivo Study on LPS Stimulated Whole Blood Authors: Gugliandolo E, Palma E, Peritore AF, et al. Year: 2021 Key Findings: CBD showed anti-inflammatory and immunomodulating effects in dog blood samples, reducing pro-inflammatory markers like COX-2. Encourages further in vivo studies for conditions like allergies or arthritis. Link: https://pmc.ncbi.nlm.nih.gov/articles/PMC8473042/

​

  • Cannabidiol-Based Natural Health Products for Companion Animals: Recent Advances in the Management of Anxiety, Pain, and Inflammation Authors: Bhathal A, Spreng D, LeRoy B, Wakshlag JJ Year: 2021 (updated references to 2023) Key Findings: Reviews CBD for anxiety (noise-induced fear), pain (chronic OA), and inflammation in dogs and cats. Well-tolerated at 2-4 mg/kg, with liver enzyme elevations noted. Significant gap in cat data for anxiety and pain. Link: https://pubmed.ncbi.nlm.nih.gov/34391060/

​

  • CBD for Pets: Navigating Quality Assurance, Safety Standards, and Marketing Strategies Authors: Bradley S, Young S Year: 2025 Key Findings: Daily 4 mg/kg CBD tolerated in healthy dogs and cats; mild side effects like lethargy. Lists conditions like pain, inflammation, and anxiety where CBD shows promise based on peer-reviewed data. Link: https://pmc.ncbi.nlm.nih.gov/articles/PMC11755934/

​

  • A Preliminary Evaluation of the Comparative Efficacy of Gel-Based Versus Oil-Based Cannabidiol Delivery in Healthy Shelter Dogs Authors: Various (MDPI publication) Year: 2025 Key Findings: Both gel and oil forms of CBD reduced acute stress in shelter dogs, with gel showing slightly better absorption for quick relief. Supports use for behavioral wellness. Link: https://www.mdpi.com/2306-7381/12/4/342

  • Daily Dosing of Cannabidiol (CBD) Demonstrates a Positive Effect on Measures of Stress in Dogs During Repeated Exposure to Car Travel Authors: Flint HE, et al. Year: 2024 Key Findings: Multiple doses of 4 mg/kg CBD over 6 months mitigated stress (cortisol, whining, lip licking) in dogs; significant reductions vs. placebo.
