Lily and dogs

CAUTION
Severity: Low

True lilies (Lilium and Hemerocallis species) are significantly less dangerous to dogs than to cats. They may cause mild GI upset but rarely cause kidney failure. Peace lily and calla lily are mild irritants for dogs. Still worth contacting your vet.

Onset

0-2 hours

Symptoms

  • - vomiting
  • - lethargy
  • - mild GI upset

What to do now

Contact your vet for advice. Monitor for vomiting and GI symptoms. Rush to vet if serious symptoms develop.

Toxicity is dose-dependent. Your dog's weight and the quantity consumed are both important - include these when you call poison control.

Lily and cats

EMERGENCY
Severity: Critical

ALL parts of true lilies (Lilium and Hemerocallis species) are extremely toxic to cats. Even a few pollen grains on the coat that are groomed off can cause acute kidney failure. There is no antidote - treatment must begin within hours to prevent irreversible kidney damage. The peace lily and calla lily cause different, milder symptoms.

Onset

0-2 hours for initial symptoms; kidney failure 24-72 hours

Symptoms

  • - vomiting
  • - lethargy
  • - drooling
  • - loss of appetite
  • - acute kidney failure
  • - death within 3-7 days if untreated

What to do now

CRITICAL EMERGENCY. Rush to an emergency vet immediately. Do not wait for symptoms. Even small exposures can be fatal. Call ASPCA Poison Control (888-426-4435) while in transit.
