Are Snake Plants Toxic to Dogs?
Snake plants (scientific name: Sansevieria trifasciata), also known as mother-in-law’s tongue, are popular houseplants cherished for their architectural leaves and low-maintenance nature. While they are excellent air purifiers and aesthetic additions to homes, pet owners should be cautious, especially those with dogs. The question often arises: Are snake plants toxic to dogs? The answer is yes.
Why Are Snake Plants Toxic to Dogs?
Snake plants contain chemical compounds called saponins, which the plant naturally produces as a defense mechanism against insects, fungi, and grazing animals. While these compounds serve the plant well, they can cause a range of unpleasant symptoms in dogs if ingested.
Symptoms of Snake Plant Poisoning in Dogs
If a dog chews on or consumes parts of a snake plant, it may exhibit the following signs of toxicity:
- Nausea
- Vomiting
- Diarrhea
- Excessive drooling
- Loss of appetite
- Lethargy or general weakness
The severity of the symptoms can vary depending on the size of the dog and how much of the plant was consumed. Most cases are mild to moderate, but any ingestion should be taken seriously.

What to Do if Your Dog Eats a Snake Plant
If you suspect your dog has eaten part of a snake plant, follow these steps:
- Remove access to the plant to prevent further ingestion.
- Rinse your dog’s mouth with water if there’s any visible plant residue.
- Monitor for symptoms and note any changes in behavior or appetite.
- Call your veterinarian or a pet poison control center, such as the ASPCA Animal Poison Control Center, for advice.
- Seek emergency care if symptoms are severe or persistent.
Prompt treatment can help prevent complications and ensure your dog recovers quickly.
How to Keep Dogs Safe from Snake Plants
If you love both plants and pets, it’s important to create a safe environment. Here are a few tips:
- Keep snake plants out of reach—place them on high shelves or in rooms off-limits to your dog.
- Train your dog to avoid chewing on plants.
- Consider non-toxic alternatives like spider plants, areca palms, or Boston ferns.
- Use deterrent sprays to discourage chewing behavior.
Final Thoughts
While snake plants are beautiful and easy to care for, they do pose a toxic risk to dogs. Awareness and preventive steps can help ensure a safe living space for both your leafy companions and your furry friends. If you're a pet parent, always research plant toxicity before bringing new greenery into your home.
