Why THC products are dangerous for pets
THC binds to cannabinoid receptors in the central nervous system, causing profound depression of neurological function. Pets lack the enzymatic pathways to metabolise THC efficiently, so even tiny amounts produce exaggerated and prolonged effects compared to humans. Concentrate products such as shatter, wax, and vape cartridges contain 60–90% THC by weight — a fraction of what a dog licks or chews can deliver a massive dose.
Owners often miss the exposure because the product is hidden in a drawer, consumed in secret, or mistaken for a regular snack — and the dog may eat an entire package before anyone notices the smell or the empty wrapper.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of thc-edibles-concentrates poisoning
- Dilated pupils and glassy, unfocused eyes that appear within 30–90 minutes.
- Extreme lethargy or inability to stand, sometimes described as being "stoned" or intoxicated.
- Incoordination, wide-based stance, and tremors that worsen with movement.
- Drooling, vomiting, or occasional diarrhoea.
- Low heart rate and lowered blood pressure leading to bradycardia.
- Paradoxical hyperactivity or agitation in some cases, followed by profound sedation.
What to do right now
- Call your vet or a pet poison helpline immediately — bring the product packaging so the clinician can estimate the THC concentration and total dose ingested.
- Do NOT induce vomiting unless specifically instructed by a veterinarian, especially if the animal is already sedated or uncoordinated — aspiration is a serious risk.
- Keep the pet in a quiet, dimly lit, safe room with soft bedding to prevent injury from stumbling or disorientation.
- Monitor breathing and gum colour closely; if breathing becomes laboured or gums turn pale, seek emergency care without delay.
- Note the approximate time of ingestion and estimate how much was eaten — this information directly guides whether activated charcoal or supportive care is needed.
