How Long Does CBD Last in Dogs?
CBD is becoming a popular supplement for dogs with anxiety, pain, arthritis, or seizures. But one of the most common questions pet owners ask is:
“How long does CBD last in dogs?”
CBD typically lasts 4–8 hours in dogs, depending on:
- The dog’s size and breed
- The type of CBD product used
- Dosage amount
- Individual metabolism
In this guide, we’ll explain how long CBD stays active in your dog’s system, how to dose it properly, and tips for safe use.
What Is CBD for Dogs?
CBD (Cannabidiol) is a natural compound from hemp plants. It is non-psychoactive (won’t get your dog “high”) and is often used for:
- Anxiety or stress relief
- Pain management
- Arthritis and joint support
- Seizure control
Veterinarians and pet wellness experts recommend CBD products specifically formulated for pets—not human CBD oils, which may contain unsafe ingredients like xylitol or high THC.
How Long Does CBD Last in Dogs?
General Guideline: 4–8 Hours
| Dog Size | Duration of CBD Effects |
|---|---|
| Small Dogs (<20 lbs) | 4–6 hours |
| Medium Dogs (20–60 lbs) | 5–7 hours |
| Large Dogs (60+ lbs) | 6–8 hours |
Factors That Affect How Long CBD Lasts in Dogs
Dog’s Size and Weight
Larger dogs usually process CBD more slowly, which can make the effects last longer compared to smaller dogs.
Metabolism
Active dogs with fast metabolisms may experience shorter CBD effects, while older or less active pets may process CBD more slowly.
Type of CBD Product
| CBD Product Type | Effect Duration |
|---|---|
| CBD Oil/Tinctures | 4–6 hours |
| CBD Treats or Chews | 6–8 hours |
| CBD Capsules | 6–8 hours |
Dosage Amount
Higher doses of CBD can last longer, but start low and go slow to avoid side effects like:
- Excessive sleepiness
- Diarrhea (in rare cases)
- Dry mouth
How Long Does CBD Stay in a Dog’s System?
CBD can stay in your dog’s bloodstream for up to 24–48 hours, but the noticeable effects usually wear off after 4–8 hours.
How Often Should You Give Your Dog CBD?
Most pet owners give CBD:
- Once or twice daily, depending on the condition
- For chronic conditions (like arthritis)—CBD is usually given every 8–12 hours
- For situational anxiety (like fireworks or vet visits)—CBD is given 30–60 minutes before the event
Can Dogs Build a Tolerance to CBD?
Most dogs do not build a significant tolerance to CBD, but you may need to adjust the dosage over time depending on:
- Changes in weight
- Severity of symptoms
- Activity level
How to Dose CBD for Dogs Safely
General Dosage Guideline:
| Dog’s Weight | Starting Dose (CBD Oil) |
|---|---|
| Under 20 lbs | 1–2 mg per dose |
| 20–60 lbs | 3–5 mg per dose |
| Over 60 lbs | 6–10 mg per dose |
Tips for Safe Use:
- Use pet-specific CBD products only
- Look for third-party lab-tested products
