Walk into any pet store or scroll through any online shop, and you will see “hemp oil” and “CBD oil” for dogs sitting side by side. Many owners think they are the same thing. They are not.
Hemp seed oil is a food oil, rich in healthy fats. CBD oil contains cannabidiol, a compound that researchers have studied for joint pain and seizures in dogs. Mixing them up can mean paying for a product that cannot do what you bought it for.
This guide explains the real differences, what the research says, the side effects, and how to choose a safe product for your dog.
This article is general information, not veterinary advice. Always talk to your veterinarian before giving your dog any supplement, especially if your dog takes other medicines.
The Short Answer
Hemp seed oil is pressed from hemp seeds. It contains omega fatty acids that support skin and coat health, but it has little or no CBD.
CBD oil is extracted from the flowers and leaves of the hemp plant. It contains cannabidiol, which has been studied for pain and seizures in dogs.
If you want a shinier coat, hemp seed oil can help. If your vet is considering support for joint pain or seizures, CBD oil is the one that has research behind it.
What Is Hemp Seed Oil?
Hemp seed oil is made by cold-pressing the seeds of the hemp plant, much like olive oil is pressed from olives. The seeds contain almost no cannabinoids. A lab analysis of commercial hemp seed oils found only small, varying traces of cannabinoids, which come from plant material touching the seeds during harvest.
What hemp seed oil does have is fat. It contains omega-6 and omega-3 fatty acids in a ratio of about 3 to 1, plus gamma-linolenic acid (GLA). These fats support skin health and a glossy coat.
Think of hemp seed oil as a food topper, similar to fish oil or flaxseed oil. It is not a medicine.
What Is CBD Oil for Dogs?
CBD oil is made by extracting cannabidiol from the flowers, leaves, and stalks of the hemp plant. The extract is then mixed with a carrier oil, such as MCT oil or, sometimes, hemp seed oil.
CBD works with the endocannabinoid system, a network of receptors that helps regulate pain, mood, and other body functions in dogs and people. Unlike THC, CBD does not make a dog “high.”
Pet CBD oils come in three types. CBD isolate contains only CBD. Broad spectrum contains CBD and other hemp compounds, with the THC removed. Full spectrum contains all hemp compounds, including trace amounts of THC.

What the Research Says About CBD for Dogs
Joint Pain and Osteoarthritis
In a 2018 study at Cornell University, dogs with osteoarthritis received 2 mg of CBD per kg of body weight twice a day for four weeks. Pain scores dropped and activity improved compared with a placebo oil. CBD reached its highest level in the blood about 1.5 hours after each dose.
Seizures and Epilepsy
A 2019 study by Colorado State University, published in the Journal of the American Veterinary Medical Association, gave CBD to dogs with hard-to-control epilepsy alongside their regular seizure medicine. 89% of the dogs that got CBD had fewer seizures. The study was small, with only nine dogs in the CBD group, so larger studies are still needed.
Anxiety
Many owners use CBD for anxiety, but the research is limited and mixed. Cornell’s canine health center notes that stronger studies are needed before CBD can be recommended for behavior problems.
Long-Term Safety
A six-month study published in the Journal of Veterinary Internal Medicine found that healthy adult dogs generally tolerated daily CBD. A 2023 research review reached a similar conclusion but pointed out a raised liver enzyme level in some dogs.
What Hemp Seed Oil Can and Cannot Do
Hemp seed oil can support dry, itchy skin and a dull coat, thanks to its fatty acids. Some owners also use it as a general wellness topper.
What it cannot do is treat pain, seizures, or anxiety. Those benefits come from CBD, and hemp seed oil has almost none. Be careful with products labeled “hemp oil for dogs” that promise to calm your dog or ease joint pain. If the label does not list a CBD amount in milligrams, you are most likely buying hemp seed oil.
Side Effects and Safety Risks
CBD Oil Side Effects
The side effects seen in studies are usually mild. They include sleepiness, loose stools, drooling, and changes in appetite. Some dogs also show a rise in a liver enzyme called alkaline phosphatase (ALP), which usually goes back to normal after CBD is stopped.
CBD is processed by liver enzymes called cytochrome P450. This means it can change how other medicines work, including some seizure medicines, pain relievers, and antibiotics. This is the main reason to talk to your vet first.
Hemp Seed Oil Side Effects
Hemp seed oil is a fat, so too much can cause loose stools or weight gain. Start with a small amount and add it slowly.
THC Poisoning Is the Real Danger
THC, the compound in marijuana, is toxic to dogs. According to the ASPCA, signs include stumbling, drowsiness, dribbling urine, dilated pupils, a slow heart rate, and in severe cases, seizures. If you think your dog has eaten a THC product, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 right away.
Never give your dog a THC product. A well-made pet CBD oil should contain no THC or only a trace amount.
Watch Out for Xylitol
Some human CBD gummies and oils contain xylitol, a sweetener that is dangerous for dogs, even in small amounts. Only use products made for pets, and read the ingredient list every time.
How Much CBD Should You Give a Dog?
There is no FDA-approved dose of CBD for dogs. The Cornell arthritis study used 2 mg per kg twice a day, and the Colorado State epilepsy study used 2.5 mg per kg twice a day, both under veterinary supervision.
Your vet will consider your dog’s weight, health, and other medicines before suggesting a starting amount. Most vets start low and adjust slowly while watching for side effects.
Which One Should You Choose?
| Your Goal | Better Choice |
|---|---|
| Shinier coat, less dry skin | Hemp seed oil |
| Everyday diet topper | Hemp seed oil |
| Joint stiffness in an older dog | CBD oil, after talking to your vet |
| Seizures | CBD oil, only alongside your vet’s treatment plan |
| Nervousness during storms or travel | Talk to your vet first, since research is limited |
Is CBD Legal for Dogs?
Hemp-derived CBD is legal to buy in most states. However, the FDA has not approved CBD for any use in animals, and it has sent warning letters to companies that sell pet CBD with medical claims. In January 2025, the FDA asked for public input on cannabis products in veterinary practice, a first step toward clearer rules.
What your vet can say also depends on your state. California’s AB 1885, in effect since January 1, 2023, allows vets to discuss and recommend cannabis for animals. In other states, vets may be more limited. The American Veterinary Medical Association advises vets to use products labeled for animals when possible.
One more change is coming. On December 11, 2026, the federal definition of hemp will limit finished products to 0.4 mg of total THC per container. Many full spectrum pet CBD oils contain more than that, so CBD isolate and broad spectrum products will be the safer choice.
How to Choose a Safe Pet CBD Product
Start with the certificate of analysis (COA). A good brand posts a lab report for every batch, tested by an independent lab. Check that the CBD amount matches the label, THC is at or near zero, and the product passed tests for pesticides, heavy metals, and solvents.
Look for the NASC Quality Seal from the National Animal Supplement Council. Brands earn it by passing facility audits and random product testing.
Choose a product made for pets, with the CBD amount listed in milligrams per bottle and per ml. Skip anything that promises to “cure” or “treat” a disease, since no pet CBD product is approved for that.
For Brands: Packaging Pet CBD the Right Way
Pet owners read labels closely, and so do regulators. A clear label should show the CBD amount per bottle and per ml, a batch number, a QR code or link to the COA, directions, the ingredient list, and your company contact details.
At Premium CBD Packaging, we print CBD Dropper Bottle Boxes, CBD Oil Boxes, and CBD Roll Labels for pet CBD brands, with room for every detail. Orders start at 100 pieces and are ready in 8 to 10 business days. Browse more ideas in our CBD for Pets section.
FAQs About Hemp Oil and CBD Oil for Dogs
Is hemp oil the same as CBD oil for dogs?
No. Hemp seed oil comes from seeds and contains almost no CBD. CBD oil comes from the flowers and leaves and contains a listed amount of cannabidiol.
Can hemp oil make my dog high?
No. Hemp seed oil contains little or no THC, so it will not make your dog high.
Can I give my dog both hemp seed oil and CBD oil?
Many pet CBD oils already use hemp seed oil as a carrier. If you want to give both separately, ask your vet first, especially if your dog takes other medicines.
Can I use human CBD oil on my dog?
It is not a good idea. Human products may contain xylitol, essential oils, flavorings, or more THC than is safe for dogs. Use products made for pets.
How long does CBD take to work in dogs?
In the Cornell study, CBD reached its highest blood level about 1.5 hours after a dose. Effects on long-term issues like joint pain were measured over several weeks.
Can hemp seed oil help with my dog’s anxiety?
There is no good evidence that hemp seed oil helps anxiety. Research on CBD for anxiety is also limited, so talk to your vet about proven options.
Can a dog overdose on CBD?
Very high doses can cause stronger side effects like heavy sleepiness and vomiting. THC is far more dangerous. If your dog eats a large amount of any cannabis product, call your vet.
The Bottom Line
Hemp seed oil and CBD oil are not the same. Hemp seed oil is a nutrition supplement for skin and coat. CBD oil has early research for joint pain and seizures in dogs.
Whichever you choose, pick a pet-specific product with a clear label and a lab report, and talk to your vet before you start. Your dog will thank you for doing the homework.
