A hidden hazard in your garden and home
Lilies are beautiful, fragrant flowers often found in gardens and homes, but they can pose serious risks to pets. While many pet owners are aware of the extreme toxicity of lilies to cats, fewer realise that lilies can also pose dangers to dogs. Though lilies may not be as deadly for dogs as they are for cats, ingestion can still lead to serious health issues. In this article, we’ll explore the types of lilies dangerous to dogs, the symptoms of poisoning, and how to keep your dog safe.
Why lilies can be harmful to dogs
Lilies are diverse and belong to various species. Most species are perennial bulbs, and many have showy flowers or aromatic scents. Scientists refer to those of the Lilium genus as the true lilies. Many cultivars go by their scientific names, making this information useful.
The toxicity levels for dogs differ depending on the type of lily species. The main danger arises when a dog chews on or ingests any part of the plant, including leaves, flowers, stems, or bulbs. Some lilies are toxic, while others may simply cause gastrointestinal irritation, but it’s always best to avoid exposure.
Dogs are vulnerable to accidental poisoning because of their eating habits. Many pups consume anything they find, making canines more likely to become victims. For this reason, it is recommended to avoid all lily plants in the home and garden altogether since most accidents occur in the pet’s home.
Common lilies and their effects on dogs
- Peace lily (Spathiphyllum)
– Toxicity: Moderate.
– Effects: Peace lilies contain calcium oxalate crystals, which cause irritation when chewed or ingested. While this variety is not as dangerous as some others, it can still lead to painful symptoms like oral irritation, drooling, pawing at the mouth, and difficulty swallowing.
- Calla lily (Zantedeschia)
– Toxicity: Moderate.
– Effects: Similar to peace lilies, calla lilies also contain calcium oxalate crystals, leading to oral and throat irritation. Dogs may experience discomfort, but more serious symptoms, like swelling of the throat or difficulty breathing, can occur in severe cases.
- Peruvian lily (Alstroemeria)
– Toxicity: Mild.
– Effects: Peruvian lilies are less toxic compared to other species but can still cause digestive upset if ingested in large amounts. Vomiting and diarrhoea are the most common symptoms.
- Daylily (Hemerocallis)
– Toxicity: Mild to moderate.
– Effects: While daylilies are extremely toxic to cats, they are less dangerous to dogs. However, they can still cause gastrointestinal upset, including vomiting, diarrhoea, and lethargy.
- Lily of the Valley (Convallaria majalis)
– Toxicity: Severe.
– Effects: Lily of the Valley is highly toxic to dogs and contains compounds called cardiac glycosides, which can affect the heart. Ingesting even a small amount can lead to symptoms such as vomiting, diarrhoea, decreased heart rate, heart arrhythmias, and even seizures or death if not treated promptly. Puppies and senior dogs are most vulnerable to the life threatening effects.
- Easter Lily (Lilium longiflorum)
– Toxicity: Mild to moderate.
– Effects: While extremely dangerous to cats, Easter lilies are less harmful to dogs but can still cause gastrointestinal issues. Vomiting, drooling, and abdominal pain are common, and in large quantities, more severe symptoms may develop.
The variety of plants on this list only scratches the surface of the issues with lilies. The signs of poisoning may also differ because of the specific toxin and its effects.
Symptoms of lily poisoning in dogs
If your dog has come into contact with or ingested a lily, the symptoms will vary depending on the type of lily and the amount ingested. Watch for the following signs of poisoning:
– Excessive drooling
– Vomiting or diarrhoea
– Lethargy or weakness
– Loss of appetite
– Oral irritation (pawing at the mouth, swelling)
– Difficulty swallowing
– Increased heart rate or irregular heartbeat (in severe cases)
– Seizures or tremors (with highly toxic varieties like Lily of the Valley)
Symptoms can appear within hours of ingestion. If you notice any of these signs and suspect your dog has come into contact with a lily, it is important to seek veterinary help immediately.
What to do if your dog eats a lily
If you think your dog has ingested part of a lily or is showing signs of poisoning, call your vet immediately. Provide details about the type of lily (if known) and how much your dog might have ingested. If you’re not sure about the lily type, bring a photo or sample of the plant with you. Treatments may include inducing vomiting, administering activated charcoal to absorb the toxins, or providing intravenous fluids to flush the system.
NOTE: Never induce vomiting unless instructed by a veterinarian. Some substances can cause more harm if brought back up.
Preventing exposure to lilies
The best way to protect your dog from lily poisoning is to limit their exposure to the plants. Here are some practical steps:
– Remove lilies from your home and garden: Avoid planting lilies or bringing cut lilies into your home if you have pets. Opt for pet-friendly plants like sunflowers, marigolds, or zinnias instead.
– Supervise outdoor time: Keep an eye on your dog when they are outdoors, especially if you’re visiting places with lilies, such as public gardens or parks.
Educate others: Make sure family members, friends, and pet sitters are aware of the dangers lilies pose to dogs and know what to do if they are exposed.
– Use deterrents: If lilies are present in areas your dog frequents, use pet-safe deterrent sprays around the plants to discourage your dog from chewing on them.
Final thoughts
While lilies may not be as deadly to dogs as they are to cats, they can still pose a risk to your furry friend. Knowing the dangers and symptoms of lily poisoning can help you take swift action if your dog is exposed. By keeping lilies out of reach and opting for pet-safe plants, you can ensure your dog stays happy, healthy, and safe from harm.
Always consult your vet if you’re unsure about a plant’s safety for your dog, and take prompt action if you suspect poisoning. A few preventive measures can save your pet from a potentially dangerous situation.
