CBD Dosage Calculator: Dosage for Cats and Dogs
Find the right CBD dose for your cat based on weight and condition. Covers anxiety and pain with a safe step-up dosing guide and product recommendations.
Use CalculatorThis CBD Dosage Calculator is designed specifically for dog owners looking for a starting point for CBD dosing by weight and intended therapeutic purpose. As interest in pet CBD products continues to grow, the need for clear, evidence-informed dosing information has never been greater. This tool generates a suggested starting dose and target dose range for your dog based on body weight, adjustable for specific conditions including anxiety, pain, inflammation, and seizure support.
Always consult your veterinarian before starting CBD, especially if your dog takes any medications or has an existing health condition. CBD can affect drug metabolism through the cytochrome P450 enzyme pathway, which processes many common veterinary medications.

How to Start and Titrate CBD for Dogs
- Start at the lowest dose for your pet's weight and condition.
- Administer consistently at the same time each day for 2-4 weeks before evaluating response.
- If no response after 2 weeks, increase the dose by 25-50% and monitor for a further 2 weeks.
- If the dog shows adverse effects (lethargy, gastrointestinal upset, sedation beyond desired level), reduce the dose immediately.
- Once an effective dose is found, maintain it consistently and reassess every 3 months.

Frequently Asked Questions
Is CBD FDA-approved for dogs?
No. As of 2025, the FDA has not approved any CBD product for use in dogs or other companion animals. Epidiolex (a pharmaceutical-grade CBD) is approved for human epilepsy but not for veterinary use. All CBD use in pets is considered off-label and should be discussed with a veterinarian.
How do I know if CBD is working for my dog?
For anxiety, look for reduced stress signals during previously triggering situations. For arthritis, observe willingness to walk, climb stairs, and interact. For seizures, track frequency and duration using a seizure log. Give any CBD protocol at least 4-6 weeks of consistent use before drawing conclusions.
Can I give my dog too much CBD?
CBD has a wide safety margin, but high doses can cause sedation, gastrointestinal upset, and potentially elevated liver enzymes with chronic high-dose use. Stay within evidence-based dose ranges and have your vet check liver enzymes annually if using CBD long-term at higher doses.
Note: CBD products vary by strength and ingredients. Discuss CBD use with a veterinarian, especially for cats, small pets, senior pets, or pets already taking medication.
