| Vet vs poison control vs ER | Call your veterinarian for most exposures; poison control helps when dose or product potency is unclear. Go to the ER for collapse, severe agitation, seizures, or inability to walk. Chocolate-containing edibles add a second toxin risk — tell the clinician both ingredients. |
Immediate action steps
- Remove remaining edibles, flower, or concentrate and secure the area
- Note the product type (edible, butter, vape oil), amount, and time
- Call your veterinarian or pet poison control for guidance
- Keep the pet in a quiet, safe space; prevent falls from ataxia
- Do not give human CBD or THC products as an antidote
Common signs
Ataxia, dilated pupils, glazed expression, urinary dribbling, and prolonged sleepiness are frequently reported patterns.
Timestamp onset. Bring that timeline to the clinic.
Red flags
Seizures, collapse, severe agitation, or inability to walk need ER care.
Vomiting with chocolate-containing edibles raises the urgency further.
This is general information, not a diagnosis. Contact your vet for anything urgent or unclear.
FAQ
- How long can signs last?
