Marijuana may be legal in certain states, but unless it’s as a cannabis product specifically designed for pets and prescribed by their veterinarian, it still needs to be kept away from dogs and cats.

Marijuana toxicity in cats and dogs

Dogs and cats have more cannabinoid receptors than people so the effects of even small amounts of marijuana are more pronounced.

Marijuana toxicity in dogs and cats can happen when a pet eats something they shouldn’t have like an edible designed for people, part of a marijuana plant or a baked good containing marijuana.

Signs and symptoms of marijuana toxicity vary depending on the amount ingested, weight of the animal and species of dog or cat but usually develop within 30 minutes to a few hours and last as much as 72 hours.

Signs of marijuana toxicity in cats and dogs

  • Difficulty walking or standing
  • Increased sensitivity to sensory stimuli (hyperesthesia)
  • Vomiting (cats more than dogs)
  • Dilated pupils
  • Lethargy
  • Urinary incontinence

Marijuana toxicity treatment in cats and dogs

It's important to contact your veterinarian as soon as possible if you suspect your pet has eaten or been affected by marijuana.

The method of exposure is also important because a “chocolate edible” may require additional treatment for chocolate toxicity, while an inhaled exposure may require treatment for respiratory issues
