Dog

Recognise the signs

  • Wobbliness, ataxia
  • Dilated pupils
  • Hypersensitivity to noise (startle to sounds)
  • Urine dribbling/incontinence (classic sign)
  • Vomiting, drooling
  • Seizures, collapse in severe cases

First aid steps

  1. Phone the vet immediately.
  2. Be honest about what was eaten — vets do not report.
  3. Bring packaging if available.

Do NOT

  • Do not lie or downplay — vets need accurate info to treat properly.
  • Do not delay due to embarrassment.
  • Do not assume CBD is safe — check THC content.

While transporting to the vet

  • Bring packaging.

When to phone the vet immediately

  • Edible with chocolate (double toxicity)
  • Severe wobbliness, seizures, unresponsive

Common causes

  • Edibles (often chocolate-based — double toxicity)
  • Cannabis flower, joints, cigarette ends
  • Hash, oils
  • CBD products with THC

What the vet will need to know

  • Product (flower, edible, oil), THC content if known
  • Amount
  • Time of ingestion
  • Other ingredients (chocolate, xylitol)

Aftercare

  • Supportive care — IV fluids, anti-emetics, anti-seizure if needed.
  • Most recover within 24-48 hours.
  • Edibles with chocolate or xylitol need additional treatment.

Prevention

  • Lock cannabis products away.
  • Brief guests.
  • Cigarette ends out of reach on walks (city dog risk).

Frequently asked questions

Will my vet report me?

No — vets focus on treating the dog. Honesty saves lives.

Is CBD safe for dogs?

Vet-formulated CBD without THC is increasingly available. Human CBD products often contain THC and other unsafe ingredients.

How long does it last?

12-24 hours typically. Severe cases longer with hospitalisation.
