Flowers may be beautiful, but there are definitely a few out there that can pose serious risks to your pets. If you live with a dog, it’s crucial to know which plants are safe. The lily family (Liliaceae), which includes about 15 genera and roughly 610 species, is particularly concerning. While plants from two genera in this family, Lilium (True lilies) and Hemerocallis (Day lilies), are deadly toxic to cats, their toxicity in dogs remains unconfirmed. The level of toxicity to canines of plants in the Liliaceae family varies across species, with some being virtually harmless while others being highly poisonous. To complicate matters further, some plants that aren’t truly lilies still include the term ‘lily’ in their names, adding to the confusion.

We can definitively say that these plants are more toxic to cats than dogs because of their varying physiologies. The best advice we can offer is to avoid adding any lilies to your garden or as houseplants in your home if you have a pet. Prevention is by far the best cure.

Examples of Toxic Lily Species

Lilies as a group are diverse. We can say most species are perennial bulbs. Many species have showy flowers or are aromatic. Scientists refer to those of the Lilium genus as the true lilies. Many cultivars go by their scientific name, making knowing this information useful.

Dogs are vulnerable to accidental poisoning because of their eating habits. Many pups consume anything they find, making canines more likely to become victims. That’s why we recommend avoiding any lily plant altogether since most accidents occur in the pet’s home. As explained, the degree of toxicity varies with the species. For example, the Easter lily (Lilium longiflorum), which belongs to the Lilium genus, is not documented as toxic to dogs, but it is extremely toxic to cats.

Species of plants in the Liliaceae family that are toxic to dogs—and cats as well—through various toxins include the following:

Learning about the hosta, or plantain lily, surprised us, given how popular the plant is for landscaping. Hostas contain saponins, which cause gastrointestinal problems in dogs, cats, and horses after eating them. Notably, rabbits and deer can eat them without suffering any ill effects. Rutgers New Jersey Agricultural Experiment Station lists it as one of the least deer-resistant species. However, the takeaway is that toxicity varies with the animal. So, just because wildlife can eat a certain plant doesn’t mean it’s safe for your dog.

Other Species of Plants Called Lilies

There are a number of plants referred to as lilies but are actually members of different families. “Lily” has come to mean any similarly looking flower, and you’ll notice much variation in this list. Toxic species to dogs that do not belong to the Liliaceae family include the following:

We’ve included the scientific names of all these species since many have several common names, further complicating their classification. Some plants have “spp.” after their genus name to indicate that many species exist under that umbrella, including many cultivars. Toxicity exists regardless of the individual species.

Signs of Poisoning

The variety of plants on our 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. For example, wild daffodils and lily of the palace contain a toxin called lycorine. This alkaloid is responsible for the signs of poisoning that follow the ingestion of this plant: vomiting, nausea, mouth irritation, abdominal pain, and diarrhea.

One of the most common signs of poisoning is vomiting. A dog only needs to consume one bulb to show signs of toxicity. The toxin is mainly concentrated in the bulb, however ingestion of the leaves is equally worrisome.

Other plants, such as calla lily and peace lily, contain insoluble calcium oxalate crystals, which can cause mouth irritation when ingested or chewed. These crystals can lead to signs like drooling, difficulty swallowing, pawing at the mouth, vomiting, and swelling of the lips and tongue.

Lily of the valley is particularly dangerous since it contains toxins that can adversely affect your pet’s cardiovascular system. Puppies and senior dogs are at the greatest risk. Tulips are also highly toxic because of their tulipalin A and B content, which causes drooling, vomiting, depression, and diarrhea. The highest concentration of these chemicals are in the bulbs and there is no known antidote.

The most common signs of toxicosis include the following:

Diagnosis and Treatment

Because of species diversity, there are various mechanisms of action when it comes to accidental poisoning. That, in turn, affects the treatment and prognosis. If you suspect your dog has eaten lilies or any poisonous plant, immediately contact your vet or the ASPCA Animal Poison Control Center hotline (888-426-4435).

Collect some of the remaining plants to take to the clinic with you for proper identification, if possible. You can also snap a picture with your smartphone. If your pet isn’t showing signs, your vet may elect to induce vomiting. Further treatment depends on the toxin and will likely include supportive care, such as intravenous fluids and anti-nausea medication.

Prompt action is critical since many flora species contain potentially life-threatening toxins. Complications from accidental poisoning may involve organ damage, requiring additional care and possible hospitalization.

Prevention

Keeping these plants from your garden and home is the best prevention. We strongly urge you to research any species to ensure it is safe for pets. Don’t assume your dog will leave them alone. A bored animal will find things to do, even stuff they shouldn’t, like eating toxic plants. Many are bitter and may deter your pup from ingesting them. However, that’s not a solution nor a wise strategy.

Final Thoughts

Hundreds of lily species exist, with varying degrees of toxicity. For example true lilies and day lilies are highly toxic to cats, while not particularly unsafe for canines. However, other plants that belong to the Liliaceae family are toxic to dogs, and many other plants going by the lily name are also poisonous to dogs and other pets. Therefore, we only recommend pet-safe plants in your home or yard to prevent accidental poisoning. By choosing pet-safe plants, you can enjoy the beauty of nature without putting your beloved companions at risk.
