7 Best CBD Oils for Small Dogs of 2026
How we ranked these
We ranked oils a small-dog owner can actually use: strength that allows tiny servings (30%), THC status and label clarity (25%), price per bottle (20%), carrier oil and flavor (15%), lab-testing transparency (10%). The scores are our editorial judgment, not customer ratings.
Small dogs need small servings, so a lower-concentration bottle is easier to measure than a high-strength one. A high-strength oil is not worse. It just gives you less room for error when the serving is a few drops.
Every competitor price and strength below was read from that brand's own store page in October 2026, not from a review site or a coupon aggregator. We dropped any brand whose page we could not read. Prices change, so check the page before you buy.
We are the #1 pick on a list we wrote, and you should weigh that. Where a competitor fits a very small dog better than we do, we say so.
Scores on this page are our own editorial ratings of other brands, judged on the criteria below. We don't rate our own products — where botanCBD appears you'll see its verified-buyer rating if it has one, and no editorial score in the ranking either way. Early customer reviews shown elsewhere on this page are labeled as such.
- ✓Strength low enough to measure a tiny serving
- ✓THC-free or clearly labeled THC status
- ✓Dog-friendly carrier oil and flavor
- ✓Fair price for the bottle size
The ranking
Furry Friends Organic Pet CBD Oil Drops 500mg
Furry Friends is 500mg of broad-spectrum CBD at 16.7 mg/mL with 0.0% THC, in an AAFCO-approved bacon flavor, for $25. We will be straight about the fit: for a 10 lb dog the serving is a few drops, so there is little room for error, and a lower-concentration bottle (several below) gives finer control. We still rank it first for the price, the THC-free formula and the batch testing, and because it works for a small dog today and a bigger one later. Ask your veterinarian for a serving size.

USDA Organic Daily Releaf Hemp Oil for Pets, 1-25 lbs (100mg)
Pet Releaf sells this oil in four strengths by dog weight, and the 1-25 lbs size is 100mg for $26.99 at petreleaf.com/products/usda-organic-daily-releaf-hemp-oil (checked October 2026). That is a fifth of our bottle's strength, which makes tiny servings easier to measure. The weight-based sizing is the clearest guidance for a small-dog owner on this list.
- Strength
- 100mg per bottle (1-25 lbs size)
- Price
- $26.99
- Sizing
- Four sizes by dog weight
Lazarus lists a 30 ml bottle at 20mg/mL for $20 at lazarusnaturals.com/products/pet-cbd-oil-tincture (checked October 2026), which works out to 600mg in the bottle. The page describes a neutral flavor you can mix into meals. It is stronger per mL than ours (16.7 mg/mL), so it is not the finest-control pick, but it is the cheapest bottle here.
- Strength
- 20 mg/mL, 30 ml
- Price
- $20
- Flavor
- Neutral, mixes into food
Broad-Spectrum CBD Oil for Dogs, 150mg
Holistapet's broad-spectrum dog oil starts at 150mg for $29.95, with Original, Chicken and Salmon flavors, at holistapet.com/products/broad-spectrum-cbd-oil-for-dogs (checked October 2026). The 150mg size is a good match for small dogs and the flavors help picky ones. It costs more than our 500mg bottle for less CBD.
- Strength
- 150mg (also 300mg and up)
- Price
- $29.95
- Flavors
- Original, chicken, salmon
Organic THC-Free CBD Tinctures for Dogs and Cats, 450mg
Joy Organics' pet tincture comes in 450mg for $34.95 and 900mg for $49.95 at joyorganics.com/products/organic-cbd-oil-tincture-for-pets (checked October 2026). The page lists two ingredients, organic olive oil and organic broad-spectrum hemp extract, with no detectable THC. It is close to ours in strength and costs $9.95 more.
- Strength

- Price
- $34.95

Broad Spectrum CBD Dog Oil Tincture, Peanut Butter 300MG

The ingredient list is hemp extract, MCT oil and natural flavors. The page suggests a full 1 mL dropper as a serving, which is a big serving for a small dog, so ask your veterinarian before using that guidance.

Charlotte's Web sells a full-spectrum dog oil titled 17MG in 30mL, chicken or unflavored, for $59.99 at charlottesweb.com/products/17mg-cbd-oil-for-dogs (checked October 2026). The page does not state a total milligram figure for the bottle. Full spectrum also means trace THC, which our THC-free pick does not have.

The bottom line
For most small-dog owners, start with a pet-formulated, THC-free oil and a veterinarian's serving advice. Furry Friends is our pick at $25. If your dog is under 15 lbs and you want the most room to measure, Pet Releaf's 100mg size or Holistapet's 150mg is a reasonable alternative. Start low, go slow, and tell your veterinarian what you give.

FAQ
What is the best CBD oil for small dogs?
Look for a pet-formulated oil, tested by a third-party lab, with a strength low enough to measure a tiny serving. Our pick is Furry Friends 500mg ($25, 16.7 mg/mL, 0.0% THC), and lower-strength bottles from Pet Releaf and Holistapet give finer control for very small dogs.
Is a lower-strength CBD oil better for a small dog?
Not better, but easier to measure. A small dog's serving is a few drops of a 16.7 mg/mL oil, so a lower-concentration bottle leaves less room for error. Ask your veterinarian for a serving size either way.
Should a small dog get THC-free CBD oil?
We recommend it. Dogs are small and sensitive, so a THC-free broad-spectrum oil like Furry Friends (0.0% THC) removes one variable. Check the lab report for any oil you buy.
Can I use human CBD oil for my small dog?
We suggest a pet-formulated oil instead. Human oils are usually stronger and may use flavors or carriers made for people. If you are considering one, ask your veterinarian first.
How do I give CBD oil to a small dog?
Measure the serving your veterinarian gives you, then place it on a snack or in a little food, or put it inside the cheek. Start low and go slow, and keep the bottle out of reach.
