My Dog Got Into Marijuana Edibles — What Actually Happens

As legal cannabis access has expanded, vets report seeing THC toxicity in dogs far more often than they used to, and it's a strange enough presentation that a lot of owners don't initially connect the symptoms to what happened. Dogs are considerably more sensitive to THC than humans, and it's rarely fatal on its own, but it produces a genuinely alarming set of symptoms that can look like a serious neurological event.
Edibles carry compounded risk — a marijuana-infused brownie or gummy often also contains chocolate or xylitol, either of which is its own separate toxicity concern layered on top of the THC.
Symptoms to watch for: wobbliness and loss of coordination, dribbling urine, extreme lethargy or a "spaced out" glassy-eyed look, dilated pupils, and in some cases a slowed heart rate. Symptoms can last many hours.
What to do right now: being honest about what your dog got into, including cannabis, genuinely helps — it changes the treatment approach and rules out other more dangerous causes of the same symptoms (like a seizure disorder or stroke). Identifying whether it was an edible and what else was in it matters for assessing the full risk.
When it's an emergency: if breathing becomes slow or shallow, body temperature drops, or if chocolate/xylitol was also involved in an edible.
