Why it can be dangerous

Opioids and opiates are drugs designed to provide pain relief for animals and humans.[1] Accidental ingestion in oral or patch form can result in severe poisoning because opioids are rapidly absorbed by all routes of administration.[1]

Signs to watch for

  • Death
  • Coma
  • Dilated pupils
  • Sedation
  • Depression
If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
