Hemp & CBD Oil for Dogs With Arthritis & Joint Pain — Backed by a Clinical Study

If your dog is slowing down on walks, hesitating at the stairs, or taking longer to get up in the morning, you're probably looking for something that actually helps — not just another bottle with big promises. Full-spectrum hemp (CBD) oil has become one of the most popular natural options pet owners reach for to support dogs with arthritis and joint pain, and at HempMy Pet we've done something almost no other brand has: we put our own hemp oil through a 90-day clinical trial with Colorado State University researchers. This page walks you through what arthritis looks like in dogs, what the research really shows, how hemp works in your dog's body, and how to choose and give it well.

Does Hemp Oil Really Help Dogs With Arthritis? What Our Clinical Trial Found

Most pet CBD brands point to someone else's research. We ran our own. HempMy Pet's first clinical trial was a 90-day study of 30 dogs living with chronic joint discomfort, overseen by Dr. Robin Downing, DVM of the Downing Center for Animal Pain Management, with Lori Kogan, Ph.D. and Peter W. Hellyer, DVM of Colorado State University's College of Veterinary Medicine & Biomedical Sciences. Owners gave their dogs our full-spectrum hemp oil and rated their comfort and mobility every two weeks.

The results were striking: more than 93% of the dogs showed a benefit, and 94% of owners reported their dog's quality of life had improved. The full study — "The Use of Cannabidiol-Rich Hemp Oil Extract to Treat Canine Osteoarthritis-Related Pain" — was published in the Journal of the American Holistic Veterinary Medical Association. You can read the full published study (PDF) or see our clinical research overview, with independent coverage from BizWest.

That university-backed research is the difference between hoping a product works and having real, owner-reported evidence behind it — and it's the foundation of every formula on this page.

Signs of Arthritis and Joint Pain in Dogs

Arthritis (most often osteoarthritis) is a progressive wearing-down of the joints that's especially common in senior dogs and larger breeds. Dogs are experts at hiding discomfort, so the early signs are easy to miss. Watch for:

• Stiffness or limping, especially after rest or first thing in the morning
• Hesitating at stairs, jumps, or the car — or needing a running start
• Slowing down on walks, lagging behind, or tiring quickly
• Licking or chewing at a joint, or new sensitivity to touch
• Less interest in play, or trouble settling into a comfortable position
• Subtle mood changes — more withdrawn or irritable than usual

If you're seeing these signs, the first step is a vet visit to confirm what's going on. Once arthritis is diagnosed, hemp can become one part of a comfortable, active senior life — alongside the other steps we cover below.

How Hemp & CBD Work for Canine Joint Pain

Dogs — like all mammals — have an endocannabinoid system (ECS), a network of receptors (called CB1 and CB2) that helps regulate comfort, mood, sleep, and the body's inflammatory response. The cannabinoids in full-spectrum hemp interact with this system to support your dog's natural sense of balance and everyday comfort.

Because our oils are full-spectrum, the CBD works alongside minor cannabinoids like CBG and CBC plus natural terpenes — a cooperative effect researchers call the "entourage effect" — rather than relying on isolated CBD alone. For a veterinary-school overview of how CBD from hemp works in dogs, see Cornell University's Riney Canine Health Center.

What the Research Says About CBD for Dog Arthritis

Research into hemp and canine joint health is still young, but the signs are encouraging — and it's growing every year:

• HempMy Pet × Colorado State University (90-day trial): 93%+ of dogs showed a benefit and 94% of owners reported improved quality of life using our full-spectrum hemp oil.
• Cornell University (2018): A landmark study found that CBD at 2 mg per kg twice daily increased comfort and activity in dogs with osteoarthritis, compared to placebo, with no significant side effects.
• Veterinary consensus: The American Veterinary Medical Association is actively encouraging more controlled research; you can read its overview on cannabis use and pets.

The honest bottom line: hemp is not a cure for arthritis — nothing is — but a growing body of research, including our own university-supported trial, points to meaningful support for joint comfort and mobility in many dogs.

Researcher Credentials

This study was a collaborative effort between HempMy Pet™, Dr. Robin Downing — a world-renowned veterinary pain specialist and Hospital Director of the Downing Center for Animal Pain Management in Windsor, CO — and researchers Dr. Lori Kogan and Dr. Peter Hellyer of the College of Veterinary Medicine and Biomedical Sciences at Colorado State University.

Why Full-Spectrum Hemp Quality Matters for Arthritis

For a dog dealing with daily joint discomfort, what's actually in the bottle matters more than the label on the front. Here's what separates a hemp oil worth giving from one that isn't:

Full-Spectrum, Never Isolate

Isolate is pure CBD stripped of everything else. Full-spectrum keeps the natural range of cannabinoids and terpenes intact, which most owners and researchers prefer for a more complete effect. We only make full-spectrum.

A Real Certificate of Analysis (COA)

A trustworthy brand publishes third-party lab results confirming the cannabinoid content and showing the product is clean — free of pesticides, heavy metals, and solvents — with THC under the legal 0.3%. Every HempMy Pet batch is third-party tested.

Seed-to-Sale, Grown in Colorado

Most "pet CBD" brands buy bulk extract from third parties — sometimes imported. We breed our own hemp genetics, grow them on our Colorado farm using organic practices, and formulate every batch in-house under human-grade standards. Nothing is sourced from overseas. That control is exactly what made it possible to stand behind a clinical trial.

The Right Carrier Oil

The carrier affects absorption and taste. Coconut (MCT) oil is prized for fast absorption, organic hemp seed oil adds omega fatty acids, and olive oil is gentle and palatable for big dogs. We offer all three so you can match the carrier to your dog.

How Much Hemp to Give a Dog With Arthritis

The golden rule is start low and go slow. For joint support, a common starting point owners and researchers use is roughly 1–2 mg of CBD per 10 lbs of body weight, once or twice daily — close to the 2 mg/kg twice-daily amount used in the Cornell osteoarthritis study. Begin on the low end, then adjust over a week or two based on how your dog responds.

General starting guide by weight:

Dog's Weight	Typical Daily Starting Range (CBD)
Up to 25 lbs	~2–5 mg
25–50 lbs	~5–10 mg
50–75 lbs	~10–15 mg
75 lbs+	~15–20 mg

Because the exact serving depends on the strength you choose, each product below has its own dosing-by-weight chart on its page — open the formula that fits your dog for precise guidance. If your dog takes other medications or has a health condition, check with your veterinarian before starting.

Hemp Oil, Omega-3s, and Joint Supplements: A Complete Plan

Hemp works best as part of a well-rounded approach to arthritis, not as the only tool. Veterinarians generally recommend managing canine joint pain from several angles at once:

• Maintain a healthy weight — extra pounds put direct load on sore joints; this is one of the highest-impact things you can do.
• Gentle, low-impact exercise — regular short walks and swimming keep joints mobile without overloading them.
• Omega-3 fatty acids — our hemp-seed and coconut carriers naturally provide omega fatty acids that support a healthy inflammatory response.
• Veterinary pain management — for some dogs, NSAIDs or other medications prescribed by your vet are an important part of the plan; always tell your vet what supplements your dog takes.
• Full-spectrum hemp — for daily joint-comfort and mobility support, alongside the steps above.

How to Give Hemp to a Dog With Arthritis

Oils are simple: drop the measured serving directly in your dog's mouth, or mix it into food or a favorite treat. For arthritis, consistency matters more than a single large dose — give it daily so your dog's endocannabinoid system has steady support, and give it time. Many owners begin noticing changes in comfort and movement within a couple of weeks of regular use. If your dog won't take oil, the treats are an easy swap.

Is Hemp Safe for Dogs With Arthritis?

Hemp-derived products containing less than 0.3% THC are federally legal under the 2018 Farm Bill, and full-spectrum hemp at proper serving sizes is non-intoxicating — it will not get your dog "high." Hemp is generally well tolerated; if you give more than your dog needs, the most common signs are mild drowsiness, wobbliness, or loose stool, which pass on their own. That's exactly why we recommend starting low. Because arthritic dogs are often on other medications, talk with your veterinarian before starting hemp. For more owner-focused background, the American Kennel Club has a helpful overview.

Frequently Asked Questions

Is hemp oil good for dogs with arthritis pain?
Many owners use full-spectrum hemp oil to support joint comfort and mobility in dogs with arthritis. In our 90-day Colorado State University-supported clinical trial, 94% of owners reported their dog's quality of life improved. Quality matters — look for organic, full-spectrum, third-party-tested oil like ours.

How long does it take for hemp oil to work for a dog's joints?
Some owners notice a calmer, more comfortable dog within the first hour, but for arthritis and joint support the bigger changes usually show up with consistent daily use over one to two weeks. Give it time and keep servings consistent.

Can I give my dog hemp oil every day?
Yes — daily use is exactly how hemp is meant to be given for joint support, since steady, consistent servings help your dog's endocannabinoid system stay balanced. Start low, go slow, and keep it part of the routine.

What are the side effects of hemp oil for dogs?
At appropriate servings, side effects are uncommon and mild — usually drowsiness, slight wobbliness, or loose stool if you give too much. These pass on their own, which is why we recommend starting on the low end and adjusting slowly.

Which is better for a dog's arthritis, hemp oil or CBD oil?
They're usually the same thing under two names — both are hemp-derived and contain CBD. What matters is that it's full-spectrum hemp extract (not seed-only oil and not isolate), third-party tested, and dosed for your dog's weight.

What's the best hemp oil for a senior dog with stiff joints?
For larger and senior dogs, most owners start with our 1000mg Hemp Oil or 5000mg Olive Oil for higher daily servings; smaller dogs do well on the 250mg or 500mg formulas. All are full-spectrum and third-party tested.

Give Your Dog Comfortable Days Again

Arthritis doesn't have to mean the end of good walks and easy mornings. Start with the strength that fits your dog — the 250mg Hemp Oil for small and medium dogs, or the 1000mg Hemp Oil for large breeds — and give it consistently as part of a complete joint-care plan.
