opens in a new tabDiagnosing lily poisoning in dogs
The first step in diagnosing lily poisoning is identifying the type of lily your dog was exposed to. If you’re not super into plants and are unsure of the name of the plant, you can talk to a knowledgeable friend, call a local garden center, or consult a plant identification website or app for help.
Once you’ve figured out what your dog ate, contact your veterinarian’s office, a local emergency vet clinic, or an animal poison control centeropens in a new tab to figure out if your dog is in any danger and what should be done. If your dog is showing any symptoms, just take them to the vet first and figure out the rest later.
Symptoms of lily poisoning in dogs
The symptoms of lily ingestion will vary based on the type of lily eaten. Some common symptoms and the lilies that cause them include the following:
Mild vomiting:
True lilies (Lilium spp.), including Easter, tiger, Asiatic, and stargazer lilies
Day lily (Hemerocallis spp.)
Canna lily (Cannaceae spp.)
Oral irritation, tongue swelling:
Peace lilies (Spathiphyllum spp.)
Calla lilies (Zantedeschia spp.)
Severe vomiting and diarrhea:
Lily of the Nile (Agapanthus africanus)
Plantain lily (Hosta plantaginea)
Cardiac arrhythmia, weakness:
Lily of the Valley (Convallaria spp.); can also cause vomiting
Treatment
Treatment for lily ingestion will vary based on the type of lily ingested and the dog’s symptoms. Dogs with mild vomiting may not require any treatment or could be treated with an anti-nausea medication alone. Dogs with tongue swelling may need to be monitored in the hospital and given pain control medication. More severe vomiting and diarrhea may require hospitalization for anti-nausea medication and IV fluids. Cardiac arrhythmias may require ECG monitoring, heart medication, or even a temporary pacemakeropens in a new tab.
Why are lilies dangerous to dogs?
Some false lilies contain different toxins that make them dangerous for dogs to ingest or chew on:
Peace lilies and calla lilies are full of calcium oxalate crystals, which are tiny crystals that cause severe irritation to any tissues they contact, most commonly in the mouth, throat, and stomach.
Lily of the Nile contains alkaloids, which are most concentrated in the bulb of the plant, and cause GI upset and abdominal pain.
Plantain lilies are coated in saponins, which are bitter-tasting substances that plants use to protect themselves from curious animals.
Lily of the valley is the most dangerous of the false lilies. They’re full of cardiac glycosides, which affect the heart’s normal rhythm.
How to prevent plant poisoning:
The best way to prevent plant poisoning is to check to make sure that any plants you bring into your indoor or outdoor environment are safe for your dog. Do this before you bring the plant home, not after splurging at a local nursery. Even well-behaved dogs may get curious about a new plant, so keeping dangerous plants away from them is safest.
Are all parts of lilies poisonous to dogs?
In toxic false lilies, all parts of the plant should be considered poisonous. Some plants may have increased amounts of toxin in a certain area (like the alkaloids in the bulb of the lily of the Nile), but it’s best to assume that no part of a toxic plant is safe for your dog.
How do I stop my dog from eating lilies?
The best way to stop your dog from eating lilies is to keep them out of your dog’s environment. If this isn’t entirely possible, keeping them elevated enough that your dog can’t reach them and monitoring any leaves or flowers that are about to drop can help to prevent problems.
If your dog happens to chew on an unknown or toxic plant, having a “drop it” or “leave it” cue in your arsenal can be helpful. This cue can be trained at any age and is great for recovering things your sneaky pup snatches.
The bottom line: Are lilies poisonous for my dog?
