THC Toxicity in Pets: What Every Pet Owner Should Know

THC Toxicity in Pets

As marijuana use becomes more common, so do cases of accidental exposure in pets. While some people may view marijuana as “natural” or harmless, it can be very dangerous for animals. Dogs and cats are far more sensitive to THC (the psychoactive component of marijuana) than humans. Even a small amount can cause serious illness.

How Pets Can Be Exposed to Marijuana

Pets may come into contact with marijuana in several ways, including:

  • Eating edibles such as brownies, cookies, or candies

  • Ingesting marijuana-related products like oils, tinctures, or inhalers

  • Breathing in secondhand smoke

  • Eating ashes, discarded joint butts, or marijuana buds/flowers

Signs of THC Toxicity in Pets

Symptoms can appear within minutes to hours after exposure and may last for hours to days. Watch for:

  • Lethargy or extreme tiredness

  • Whining, crying, or agitation

  • Dilated pupils or glassy eyes

  • Dazed expression or confusion

  • Difficulty walking or wobbliness

  • Incontinence or urine dribbling

  • Vomiting

  • Overreaction to sounds or touch

  • Abnormal heart rate (too slow or too fast)

  • Changes in body temperature

  • Tremors, seizures, or even coma in severe cases

What to Do if Your Pet Is Exposed

If you suspect your pet has ingested or inhaled marijuana, do not wait for symptoms to worsen. Prompt veterinary care can make a huge difference in your pet’s recovery.
