If your pet ate a cannabis edible, call a veterinary poison control service or an emergency vet immediately, before waiting for symptoms. Give them the pet's weight, the time of ingestion, and the THC and milligram amount from the packaging. Most pets survive THC ingestion with supportive care, but edibles often also contain chocolate, xylitol, or raisins that are dangerous on their own.

Act in this order. Speed matters because symptoms can start within 30 to 60 minutes and peak around 4 to 6 hours.

  1. Call for guidance. Contact your veterinarian, an emergency clinic, the ASPCA Animal Poison Control Center at (888) 426-4435, or the Pet Poison Helpline at (855) 764-7661. A consultation fee may apply, and both services run 24 hours.
  2. Keep the packaging. The label tells the vet the THC dose, the CBD ratio, and whether chocolate, xylitol, macadamia nuts, or raisins are present.
  3. Note the details. Record the time, the amount eaten relative to body weight, and your pet's current behavior.
  4. Do not induce vomiting unless a vet tells you to. Vomiting is risky once a pet is wobbly or drowsy because of aspiration.
  5. Keep your pet calm, warm, and confined. Block access to stairs, furniture, and water bowls if swallowing is uncoordinated.

How Much THC Is Dangerous for a Pet?

There is no established safe dose, and dogs are more sensitive to THC than humans are. A single 10 mg edible can cause obvious intoxication in a small dog, and severe signs are more likely as the milligrams per kilogram of body weight rise. Cats are also affected, though they are exposed less often because they rarely eat edibles voluntarily.

Some pets become agitated instead of sedated, especially with high-dose products or edibles that also contain chocolate.

How Long Does a Cannabis High Last in a Pet?

Most pets improve within 12 to 24 hours, but signs can persist for 24 to 72 hours after a large edible dose. Fat-based products such as butter, oil, or chocolate-containing edibles are absorbed slowly and can prolong the effect. Never let a pet "sleep it off" without veterinary advice, because tremors and low body temperature need treatment.

What Else in the Edible Could Be Toxic?

The THC is only part of the risk. Check the ingredient list and report every item to your vet.

What Should I NOT Do?

Avoid home remedies and internet cures. Do not give human medications, alcohol, activated charcoal, or hydrogen peroxide without direct veterinary instruction. Do not force food or water on a drowsy pet, and do not leave them unattended near stairs, pools, or balconies.

What Will the Vet Do?

Treatment is supportive and depends on how the pet presents. Your vet may induce vomiting if ingestion was recent and the pet is stable, give activated charcoal, start IV fluids, provide anti-nausea or anti-tremor medication, and monitor heart rate, temperature, and blood glucose. Most pets go home within a day once they can walk and eat normally.

How Do I Prevent It From Happening Again?

Store all cannabis products in a locked container, well above counter height, and never in a bedside drawer or purse. Keep edibles in their original child-resistant packaging so the dose is always readable. Treat cannabis like any other medication in the house: out of sight, out of reach, and counted.
