My dog ate Humulus lupulus — what to do

Step by step

  1. Take humulus lupulus away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
