A:1 | Mobility & Joint Support
A proprietary blend of CBD, THC, CBDa, and CBG with select terpenes, boosted by Magnesium and B-Complex - developed over six years to help support mobility and healthy joints, for dogs and cats.
Why A:1 is different
From young dogs and cats feeling the effects of panosteitis, to a senior companion feeling the effects of age, A:1's blend works to support joint and mobility needs and helps support a healthy inflammatory response, through our proprietary formula. This formula is built around the Entourage Effect, well known in medical cannabinoid science, which brings out the best of the plant to maximize the benefit for your cat or dog.
Right:Ratio's A:1 formula isn't just a standard CBD oil - we've incorporated multiple nutrients and elements to provide the relief pets need so they can live their best life, whether the joint and mobility issue is temporary or ongoing.
This proprietary blend was painstakingly crafted by veterinary experts with pets of their own, so they could make sure their own loved ones had their best lives at every stage - and now the same formula is available for yours.
A:1 is safe and effective for both dogs and cats. If you'd rather use a formula built specifically around feline physiology, we also offer F:1, calibrated specifically for cats' unique needs.

What's actually in A:1

A good fit if your pet:
- Is slower to rise, settle, or climb stairs
- Shows soreness or tires quickly after walking or running
- Favors a leg or vocalizes during movement
- Has an inability to sleep or settle comfortably
Talk to your vet first if your pet:
- Is on other medications
- Has sudden, severe, or undiagnosed pain
- Is a puppy or kitten under 1 year old

Dosing & how to use
Start with the base dose on the label.
Slowly increase the dose as instructed, watching for: easier movement, more willingness to walk or play, steadier rest.
Once you see that improvement, hold at that dose - reach out anytime with questions, real support, not AI, plus a 30-day check-in by email.
Keep a consistent daily routine - don't stop abruptly.
Shake well
Shake for 30 seconds before each use.
Give by syringe
Administer into the back side of your pet's mouth using the enclosed dosing syringe.
Store properly
Keep in a cool, dark place. Do not refrigerate.

Backed by research
A sample of the researchA:1's formula is grounded in the same clinical cannabinoid science behind every Right:Ratio product. The studies below are a representative sample, curated and maintained by the Veterinary Cannabis Society, an independent nonprofit - not written or funded by Right:Ratio.
Research tells the stories
At R:R, our approach isn't static - it's informed by the latest clinical research in veterinary medicine on the use and safety of medical cannabinoids, and our own +8,000 documented CROMs (Client-Reported Outcome Measures). These are not reviews - they're clinical touchpoints we conduct with every serious medical case we've handled in the last 10 years.
“Pharmacokinetics, Safety, and Clinical Efficacy of Cannabidiol Treatment in Osteoarthritic Dogs”
One of the earliest controlled studies of CBD in dogs with osteoarthritis, examining tolerability at set doses.

Evaluated a CBD/CBDA-rich hemp extract in dogs recovering from TPLO (a common ACL-repair surgery).

Calibrated, not counted.
Most other pet supplement brands compete on milligram count alone. A:1 is calibrated with the right combination of molecules and ingredients, in exactly the right amounts, and in the right ratios - for the exact mobility support your dog or cat needs, alongside specific dosing and titration guidance.
Not a supplement guess. A clinical protocol.

A:1 independent lab certificate of analysis
A certificate of analysis (COA) is the independent lab's full report on one specific batch - which cannabinoids it contains and at exactly what levels, plus confirmation it's clear of pesticides, heavy metals, and residual solvents.

Right:Ratio A:1
"My dog was whimpering, and shortly after I gave her a dose she went to sleep. We're still finding her perfect dose, but so far I've been pleased. Her stomach is too sensitive for NSAIDs, so I'm very glad this is working for her."
Right:Ratio A:1
"Right ratio has worked great for Caesar. I did not expect him to get up and walk around the way he does. He has more energy and mobility since we started using it."
Right:Ratio A:1
"Missy's doing well, and every day with her is a blessing. Thank you!"
