19 Popular Houseplants That Are Toxic To Dogs


An estimated 33.1 million households in the United States had indoor plants in 2019. That number has likely gone up, as it followed an upward trend and as people were home more during the pandemic. If you're both a dog mom or dad and a plant mom or dad, you're not alone. Plants have been shown to be air purifiers, mood lifters, productivity boosters and overall beneficial for mental health. But many are dangerous to our canine companions. Here are 19 popular houseplants that are toxic to dogs and safe alternatives to try instead.

1. Aloe vera

Although the inner parts of Aloe vera plants are safe for dogs (the gel can be used topically on skin and fur, while the juice is safe for drinking), chewing on the plant can be dangerous. The plant contains toxins called saponins (a natural chemical produced by plants for protection from insects, microbes, and fungi) and anthraquinone glycosides that can cause gastrointestinal issues when ingested. Common symptoms include diarrhea, vomiting and lethargy.

Non-Toxic Alternative: Haworthia (or Zebra Plant)
  • Get a similar look to Aloe with Haworthia, a succulent that also has soft spines.

2. Asparagus Fern

Though its name indicates otherwise, the Asparagus fern is actually a relative of lilies, which are known to be dangerous to dogs. This means it has similar toxicity as lilies. Ingestion of or repeated exposure to asparagus fern can cause diarrhea, vomiting and skin irritation.

Non-Toxic Alternative: Boston Fern
  • For a similar, spread out fluffy look, try a Boston fern.

3. Bird Of Paradise

Bird of paradise flower plant Strelitzia houseplant indoor plants

This tropical houseplant is named after the animal called Birds-of-paradise, thanks to a beautiful flower that resembles the bird's plumage. That flower, though, is the most toxic part of this plant. That being said, ingesting any part of a Bird Of Paradise can lead to gastrointestinal irritation, nausea, vomiting, drowsiness and requires vet care.

Non-Toxic Alternative #1: Banana Palm
  • For a similarly tall plant with large leaves, try a Banana Palm.
Non-Toxic Alternative #2: Bromeliad
  • For a similarly colorful flower, though at a much smaller size, try a Bromeliad.
