Lily of the Valley & Dogs: Is Your Pup at Risk? Find Out!
The beauty of Lily of the Valley ( Convallaria majalis) is undeniable, with its delicate, bell-shaped flowers and sweet fragrance. However, if you’re a dog owner, that beauty might mask a hidden danger. It’s vital to understand the risks associated with this plant and how to protect your furry friend. This guide will walk you through everything you need to know about lily of the valley and dogs, keeping your pup safe and sound.
Identifying Lily of the Valley
Before delving into the dangers, it’s important to correctly identify the plant. Misidentification can lead to unnecessary anxiety or, worse, ignoring a real threat.
Appearance
- Flowers: Small, white, bell-shaped flowers that hang delicately from a single stem. These have a distinctive sweet scent.
- Leaves: Broad, oval-shaped leaves that are typically dark green. They grow in pairs from the base of the plant.
- Height: Usually grows to be 6-12 inches tall.
- Growth Habit: Spreads quickly through underground stems (rhizomes), often forming dense colonies.
Where it Grows
Lily of the Valley is often found in gardens, woodlands, and shady areas. It thrives in moist, well-drained soil. Be aware that it can also escape gardens and grow wild.
Similar Looking Plants
It’s easy to confuse Lily of the Valley with other plants. Make sure you correctly identify it. Some similar-looking plants include:
- False Lily of the Valley (Maianthemum dilatatum): Has similar leaves, but the flowers are star-shaped rather than bell-shaped and grow in a cluster at the top of the stem. This plant is also toxic, although generally less so.
- Solomon’s Seal (Polygonatum): Has similar leaves, but the flowers hang down from the stem beneath the leaves, rather than being arranged along a central stem.
Why is Lily of the Valley Toxic to Dogs?
Lily of the Valley contains cardiac glycosides, also known as cardenolides. These chemicals disrupt the normal electrolyte balance within heart muscle cells, impacting the heart’s ability to function correctly.
The Role of Cardiac Glycosides
These toxins affect the sodium-potassium pump, which is essential for maintaining proper heart rhythm and muscle contractions.
- Disruption: Cardiac glycosides bind to this pump, inhibiting its function.
- Consequences: This disruption leads to an increase of calcium inside heart cells, causing abnormal heart contractions and potentially life-threatening arrhythmias.
Toxicity Levels
All parts of the lily of the valley plant are toxic, including the flowers, leaves, stems, roots, and even the berries. The concentration of toxins can vary depending on the plant’s age and growing conditions. The berries, though, are usually the most poisonous part.
What Happens if Your Dog Eats Lily of the Valley?
If your dog ingests any part of the lily of the valley plant, it’s crucial to act quickly. The severity of the symptoms depends on the amount ingested and the size and health of your dog.
Symptoms to Watch For
Be vigilant and look for these symptoms:
- Gastrointestinal Upset: Vomiting, diarrhea, and loss of appetite. This is often the first sign.
- Cardiac Effects: Irregular heartbeat (arrhythmia), slowed heart rate, weakness, and collapse.
- Neurological Signs: Tremors, seizures, and dilated pupils.
- General Weakness: Lethargy and depression.
- Excessive Drooling: Sometimes accompanied by pawing at the mouth.
What to Do Immediately
- Stay Calm: Your dog will pick up on your anxiety. Try to remain calm and collected.
- Remove Access: Prevent your dog from eating any more of the plant.
- Identify the Plant: Take a sample of the plant with you (if possible) to show your veterinarian.
-

- Pet Poison Helpline: (855) 764-7661. A consultation fee may apply.
- Follow Veterinary Advice: Follow your veterinarian’s instructions carefully. They may recommend inducing vomiting (only if advised), administering activated charcoal, or providing supportive care such as IV fluids and heart monitoring.
Prevention is Key: Protecting Your Dog
The best approach is to prevent your dog from ingesting lily of the valley in the first place.
Removing the Plant
If you have lily of the valley in your garden, consider removing it, especially if your dog tends to eat plants. Remember that the rhizomes spread easily, so be thorough in your removal efforts.
Safe Gardening Practices
- Supervise Your Dog: When your dog is in the garden, keep a close eye on them.
- Train Your Dog: Teach your dog the "leave it" command. This can be a valuable tool for preventing them from eating things they shouldn’t.
- Create a Designated Dog Area: Establish a safe zone where your dog can play without access to potentially toxic plants.
- Secure Compost Piles: Compost piles can contain discarded plant material, including lily of the valley. Ensure they are properly enclosed to prevent access.
Alternatives to Lily of the Valley
Consider planting dog-friendly alternatives that offer similar aesthetic appeal without the risk:
- Creeping Phlox (Phlox subulata): Produces beautiful ground cover with abundant flowers.
- Impatiens (Impatiens walleriana): Offers a variety of colors and thrives in shady conditions.
- Sunflowers (Helianthus annuus): A cheerful and non-toxic option.
- Zinnias (Zinnia elegans): Bright and colorful flowers that are safe for dogs.
Treatment Options if Your Dog Eats Lily of the Valley
Treatment focuses on removing the toxin from the body and supporting the dog’s vital functions.
Veterinary Intervention
Your veterinarian will tailor the treatment plan to your dog’s specific condition.
- Decontamination:
- Inducing Vomiting: If ingestion occurred recently (within a few hours) and your dog is stable, your veterinarian may induce vomiting to remove the plant material from the stomach. Never induce vomiting at home without veterinary advice, as it can be dangerous.
- Activated Charcoal: Activated charcoal binds to the toxins in the digestive tract, preventing them from being absorbed into the bloodstream.
- Supportive Care:
- Intravenous (IV) Fluids: IV fluids help to maintain hydration and support kidney function.
- Heart Monitoring (ECG): Continuous monitoring of the heart’s electrical activity is essential to detect and manage arrhythmias.
- Medications: Medications may be administered to control heart rate and rhythm, reduce blood pressure, and manage seizures.
- Hospitalization:
- Severe cases may require hospitalization for close monitoring and intensive care.
Prognosis
The prognosis for dogs that ingest lily of the valley depends on several factors, including the amount ingested, the time elapsed before treatment, and the overall health of the dog. Early intervention and aggressive treatment improve the chances of a full recovery. However, severe cases can be fatal, especially if treatment is delayed.
