Best CBD Oil for Dogs in Australia 2026: Compared by mg & Cost

Straight answer: the best CBD oil for dogs in Australia in 2026 is Pure Majesty Pets Vet-Strength CBD Oil for Dogs — the only oil in this comparison that lists three named cannabinoids separately on the label: 30 mg CBD + 25 mg CBDA + 5 mg CBG in every mL (60 mg/mL, 3,600 mg per 60 mL bottle). CBDA is the same cannabinoid pairing used in most of the published Cornell-led dog studies, and almost no CBD oil sold in Australia discloses it. Isolates carried in MCT oil with sunflower lecithin, no intentionally added THC, natural bacon flavour — and at about A$0.013 per mg of cannabinoids, it costs roughly 5 to 6 times less per mg than every other oil we priced in Australia. Below: the 5 criteria vets use to judge a CBD oil, the side-by-side comparison in A$, and the dose chart in mL.

Most CBD sold for dogs is hard to compare. One brand prints "1,000 mg" on a bottle that holds 30 mL, another prints a per-dropper number, a third lists "hemp extract" without saying how much of it is actually CBD. Owners end up buying a weak oil, giving a few drops, seeing no change, and deciding that "CBD doesn't work for dogs." Often the problem is the dose in the bottle, not the cannabinoid.

This guide ranks CBD oils for dogs available in Australia on the numbers that matter — named cannabinoids, mg per mL, THC, carrier and cost per mg — using each seller's own listed figures. Australia has no big retail shelf of CBD oils for dogs: most owners who use CBD get a compounded oil prescribed by their vet. So we compared our oil with the published price list of CBD Vets Australia, a national service that supplies vet-prescribed compounded CBD. Watch out for "hemp oil for pets" in pet shops — those are usually hemp seed oil blends with no stated CBD. Pure Majesty Pets CBD Oil was formulated to win on all five criteria.

Best CBD Oil for Dogs in Australia 2026: Quick Comparison

Figures come from each seller's own product page (highest-strength oil for medium and large dogs, one-time list price in A$, checked 8 October 2026 unless stated). Cost per mg divides the price by the total cannabinoids stated on the label. Most brands only state CBD, so for them that number is CBD-only.

What the table shows: the vet-compounded 100 mg/mL oils are more concentrated than ours (60 mg/mL), and they cost 5 to 6 times more per mg. Pure Majesty Pets is the only oil here that lists CBD, CBDA and CBG separately. Compounded prices come from CBD Vets Australia's published price list dated January 2024 (express postage included) and require a vet prescription; check the current price with your vet.

What Is CBD for Dogs?

CBD (cannabidiol) is a non-intoxicating cannabinoid extracted from hemp. Dogs, like people, have an endocannabinoid system — a network of receptors involved in comfort, mood and immune signalling — which is why CBD has become one of the most researched supplements in veterinary science over the last decade. CBD for dogs usually comes as an oil you measure into food or the mouth; treats and chews exist, but they are harder to dose by body weight.

Cannabinoid	What it is	What the dog research says
CBD	The main non-intoxicating cannabinoid in hemp	Studied in dogs for joint comfort, itch and stress, with encouraging but mixed results
CBDA	The raw, acidic precursor of CBD	Reached serum levels 2–3× higher than CBD after oral dosing in a Cornell pharmacokinetic study (Wakshlag et al., 2020); used alongside CBD in most Cornell-led trials
CBG	A minor cannabinoid	Shown to be well tolerated in dogs; efficacy research is still early
THC	The intoxicating cannabinoid	Toxic to dogs — signs can appear from about 0.3–0.5 mg/kg (Merck Veterinary Manual)

CBD oil is not the same as hemp seed oil. Hemp seeds contain only trace amounts of CBD, according to the US FDA — so a "hemp oil for dogs" with no mg of CBD on the label is essentially a fatty-acid supplement.

What Vets Look for in a CBD Oil for Dogs

Strip away the marketing and five criteria decide whether a CBD oil for dogs is worth buying.

1. Named Cannabinoids, in mg per mL

"1,500 mg" on a bottle means nothing until you know the volume and what those milligrams are. A label should state each cannabinoid separately and give an amount per mL, so you can calculate a dose by weight. Pure Majesty Pets lists CBD, CBDA and CBG individually: 30 + 25 + 5 mg in every mL. Most competitors give a single CBD figure, and several give no per-mL figure at all.

2. CBD + CBDA, the Pairing Used in the Research

Most of the positive Cornell-led dog trials — for joint comfort (Gamble et al., 2018), itch (Loewinger et al., 2022) and seizure frequency as an add-on to medication (Garcia et al., 2022) — used a roughly 50:50 CBD/CBDA hemp extract at about 2 mg/kg twice daily. In a separate pharmacokinetic study, CBDA reached serum concentrations 2–3 times higher than CBD, and a lecithin-containing base gave the best CBDA absorption (Wakshlag et al., 2020). That is why our formula pairs 30 mg CBD with 25 mg CBDA and carries both in MCT oil with sunflower lecithin. Of the oils compared here, none of the compounded oils lists CBDA.

Honest note: those studies tested other companies' full-spectrum products, not our formula. They show why the CBD + CBDA approach exists — not a guaranteed result for any single product.

3. THC Control and a Certificate of Analysis

Dogs are far more sensitive to THC than people. Full-spectrum oils can contain trace THC, and several study products contained measurable THC. Our oil uses isolated CBD, CBDA and CBG with no intentionally added THC, and every batch comes with a certificate of analysis. Whatever brand you buy, ask for the batch COA and check three lines: cannabinoid amounts, total THC, and contaminants (pesticides, heavy metals, solvents).

4. Enough Concentration for a Real Dose

Published dog studies mostly used around 2 mg/kg of CBD (or CBD + CBDA) twice a day. For a 25 kg dog, that is 100 mg per day. With a 17 mg/mL oil, that means almost 6 mL a day — a 100 mL bottle lasts about two and a half weeks. With a 60 mg/mL oil, it is about 1.7 mL a day, and one 60 mL bottle lasts about five weeks. Low-concentration oils are not "gentle"; they are simply expensive per dose.

5. Cost per mg — the Number Brands Don't Print

Divide the price by the milligrams of cannabinoids and the market reorganises itself. Here is what a study-level amount of 100 mg per day for a 25 kg dog costs with each oil:

CBD oil	Cost per day (100 mg)	Cost per 30 days
Pure Majesty Pets Vet-Strength	A$1.31	A$39.17
Compounded CBD 100 mg/mL : THC 1 mg/mL (vet-prescribed)	A$6.67	A$200.00
Compounded full-spectrum CBD 100 mg/mL (vet-prescribed)	A$7.50	A$225.00
Compounded full-spectrum CBD 50 mg/mL (vet-prescribed)	A$7.67	A$230.00

Compounded prices come from CBD Vets Australia's published price list dated January 2024 and include express postage; a vet prescription and consultation are needed on top. Competitor figures are CBD-only.

For reference, the most-searched oils in the United States — ElleVet, Innovet, HolistaPet, CBDfx, Medterra, Charlotte's Web, Honest Paws and Pet Releaf — cost between US$0.036 and US$0.121 per mg at their US list prices on 8 October 2026, against US$0.009 for Pure Majesty Pets in the US.

Best CBD for Dogs with Joint Pain and Arthritis

Joint comfort is where the dog research is strongest. In the Cornell crossover trial, osteoarthritic dogs given a CBD/CBDA oil at 2 mg/kg twice daily had lower owner-rated pain scores and higher activity scores at weeks 2 and 4 (Gamble et al., 2018). A Baylor-led trial found that 50 mg/day of CBD improved a chronic pain index and vet-assessed mobility in large dogs (Verrico et al., 2020), and an Italian study saw benefits when CBD was added to standard multimodal care (Brioschi et al., 2020).

For dogs with stiff joints, look for a concentrated CBD + CBDA oil you can dose at study levels — that is exactly what Pure Majesty Pets CBD Oil is built for. Many owners pair it with structural joint support: our liquid collagen for dogs (462 mg Type I & III collagen + 48 mg UC-II per serving) or our hip and joint chews. Compare the options in our best joint supplements for dogs guide and our practical guide on how to help a dog with arthritis at home. Persistent limping always deserves a vet exam.

Best CBD for Dog Anxiety and Stress

Here the evidence is more mixed, and owners deserve to hear it. A single dose of about 4 mg/kg of CBD lowered cortisol after car travel and reduced whining in a Waltham study (Hunt et al., 2023), and daily dosing showed similar effects during repeated car travel (Flint et al., 2024). But a noise-fear test using a lower dose found no effect (Morris et al., 2020). Results seem to depend on the dose and the situation.

Our CBD oil is formulated to support calm during occasional everyday stress — new places, visitors, changes in routine. For sleep and predictable events like storms, travel or fireworks, many owners prefer our melatonin drops for dogs; see our full comparison of melatonin vs CBD for dogs and our ranking of the best calming supplements for dogs.

Best CBD for Itchy Dogs

In a double-blind trial, dogs with atopic dermatitis given a CBD/CBDA oil at about 2 mg/kg twice daily had lower owner-rated itch scores at days 14 and 28 than dogs on placebo, although visible skin lesions did not change (Loewinger et al., 2022). CBD may be one part of an itch routine, but the skin barrier itself needs building blocks. That is why owners of scratchy dogs often combine CBD with Pure Majesty Pets Liquid Collagen. Read our guide to the best itch relief for dogs with allergies for the full approach.

CBD Dosage for Dogs: Chart in mL

Most published dog studies used roughly 2 mg/kg of CBD (or CBD + CBDA) twice a day. Here is what that study amount looks like with Pure Majesty Pets CBD Oil at 60 mg of total cannabinoids per mL. Use it as a starting point for the conversation with your vet, who should set the final amount — especially if your dog takes any medication.

Dog weight	Cannabinoids per dose (2 mg/kg)	mL per dose	mL per day (twice daily)	One 60 mL bottle lasts
4.5 kg	9 mg	0.15 mL	0.3 mL	~200 days
10 kg	20 mg	0.33 mL	0.67 mL	~90 days
25 kg	50 mg	0.83 mL	1.67 mL	~36 days
36 kg	72 mg	1.2 mL	2.4 mL	~25 days
50 kg	100 mg	1.67 mL	3.33 mL	~18 days

Measure with a graduated oral syringe rather than "a dropper," and mix into a small portion of food your dog will finish. Many owners start lower and build up over one to two weeks while watching for drowsiness or soft stool.

Is CBD Safe for Dogs? Side Effects and Interactions

Across controlled studies, CBD has been generally well tolerated in healthy dogs at about 2–5 mg/kg per day for up to nine months (Bradley et al., 2022; Corsato Alvarenga et al., 2024). What to know:

• Liver enzyme ALP: the most consistent lab finding is a rise in alkaline phosphatase, usually without other liver changes. For long-term use, ask your vet about periodic bloodwork.
• Digestive signs: soft stool or drooling, mostly at high doses (10 mg/kg/day and above).
• Drowsiness or wobbliness: occasional, and more common with THC-containing products.
• Medication: CBD is processed by liver enzymes that also handle many drugs. Talk to your vet first if your dog takes any medication, especially NSAIDs or seizure medication.
• Not for: puppies under six months, pregnant or nursing dogs.

Never give dogs human CBD gummies or THC edibles — xylitol and THC are both dangerous for dogs.

In Australia, CBD is a Schedule 4 substance under the TGA's Poisons Standard and veterinary products fall under the APVMA; talk to your vet before starting.

Why Pure Majesty Pets Ranks #1

Let's be transparent about why Pure Majesty Pets Vet-Strength CBD Oil takes the top spot:

• Three named cannabinoids, each quantified — 30 mg CBD, 25 mg CBDA, 5 mg CBG per mL. No other oil in this comparison prints all its cannabinoid amounts.
• CBD + CBDA — the pairing behind most of the Cornell-led dog research, which none of the other oils here lists.
• Isolates, no intentionally added THC — with a certificate of analysis on every batch.
• Absorption-minded base — coconut MCT oil with sunflower lecithin, the type of base associated with better CBDA uptake in research.
• Real dosing maths — 60 mg/mL means study-level amounts in under 2 mL a day for most dogs.
• The lowest cost per mg of the oils we checked in Australia — about A$0.013, versus A$0.067 to A$0.077 for the others.
• Bacon flavour dogs take with food, made in North America under GMP standards — and free shipping, duties and taxes included.

Red Flags When Buying CBD for Dogs

• "Hemp oil" with no mg of CBD — likely hemp seed oil, with only trace CBD.
• Total mg without bottle volume — you can't calculate a dose.
• No batch COA — or a COA that doesn't match the batch number on your bottle.
• Full spectrum for small dogs — trace THC adds up when the dose is calculated per kg.
• Cure claims — no over-the-counter CBD product is approved to treat any disease in dogs. A brand promising to cure arthritis, seizures or cancer is telling you something about its honesty.
• Human CBD products — wrong concentrations, and sometimes xylitol or flavourings unsuitable for dogs.

The Bottom Line

The best CBD oil for dogs isn't the one with the biggest number on the box or the biggest ad budget. It's the one that tells you exactly which cannabinoids are inside, gives you enough per mL to reach study-level amounts, keeps THC out, and doesn't charge you several times more per mg for the privilege.

Pure Majesty Pets Vet-Strength CBD Oil for Dogs was built on that list: CBD + CBDA + CBG, all quantified, 60 mg/mL, isolates in MCT and lecithin, bacon-flavoured — at about A$0.013 per mg in Australia.

Give your dog the formula the research points to, at a price you can keep up.
