Devil’s ivy is toxic to dogs. The plant, also known as golden pothos or pothos, contains microscopic needle-shaped crystals called insoluble calcium oxalates that cause immediate pain and irritation when chewed. The ASPCA lists it as toxic to dogs, cats, and horses. The good news: most cases involve only mouth and throat irritation and resolve without lasting harm.
Why Devil’s Ivy Hurts Dogs
The leaves and stems of devil’s ivy are packed with tiny crystal needles stored inside specialized cells. When a dog bites into the plant, these needles shoot out and embed in the soft tissue of the mouth, tongue, and throat. Once lodged, they trigger the surrounding cells to release histamine, the same compound involved in allergic reactions. That histamine release causes rapid swelling, burning pain, and inflammation.
This is a mechanical injury, not a chemical poison that needs to be absorbed into the bloodstream. The crystals physically puncture tissue on contact. That’s why symptoms appear almost immediately, often within seconds of chewing. It also means most dogs drop the plant quickly because the pain is instant, which limits how much they actually swallow.
Symptoms to Watch For
The most common signs of devil’s ivy ingestion in dogs are:
- Oral irritation: intense burning and pain in the mouth, tongue, and lips
- Excessive drooling
- Swelling of the tongue, lips, or throat
- Pawing at the mouth
- Vomiting
- Difficulty swallowing
These symptoms typically start right away. You might notice your dog suddenly dropping the plant, shaking their head, or drooling far more than usual. Some dogs will refuse food or water afterward because their mouth is sore.
In very rare cases, severe swelling can extend to the upper airway near the larynx, causing difficulty breathing. This is uncommon because dogs usually stop chewing before consuming a large amount, but it represents the most serious potential complication. Any sign of labored breathing after plant ingestion warrants emergency veterinary care.
What to Do If Your Dog Eats It
Start by removing any remaining plant material from your dog’s mouth if you can do so safely. Then call your veterinarian or a poison control hotline. The ASPCA Poison Control Hotline (888-426-4435) and Pet Poison Helpline (855-764-7661) are both available 24/7 and can walk you through next steps specific to how much your dog ate and how they’re responding.
Do not try to induce vomiting on your own. With calcium oxalate plants, forcing the material back up can re-expose the throat to the crystals and make swelling worse. A veterinarian or poison control specialist can tell you whether vomiting is appropriate based on the situation.
If you can, bring a piece of the plant or a photo of it with you to the vet. Many houseplants share common names across different species with very different toxicity levels, so having the actual plant helps your vet confirm exactly what your dog ate. The scientific name for devil’s ivy is Epipremnum aureum, and it belongs to the Araceae family, a group of plants that nearly all contain these same irritating crystals.
How Recovery Typically Goes
Most dogs recover fully within 24 to 48 hours. The irritation is painful but self-limiting once the crystals are no longer in contact with tissue. Your vet may recommend offering cool water or a small amount of milk to help soothe the mouth, and in some cases may prescribe something to manage pain or reduce swelling. Dogs who vomited or refused to eat may need monitoring for dehydration, but serious complications from devil’s ivy alone are uncommon.
The biggest factor in severity is how much plant material the dog consumed. A single exploratory bite, which is the most common scenario, causes discomfort but rarely anything more. A dog that chewed and swallowed a significant portion of leaves could develop more pronounced throat swelling or gastrointestinal upset.
Keeping Your Dog Safe Around Houseplants
Devil’s ivy is one of the most popular houseplants because it’s nearly impossible to kill and grows long trailing vines. Those dangling vines are exactly what makes it tempting for dogs, especially puppies who chew everything. The simplest solution is placement: hang the plant high enough that even the longest trailing stems stay out of reach, or move it to a room your dog doesn’t access.
Devil’s ivy is far from the only houseplant in this category. Philodendrons, peace lilies, calla lilies, elephant ear, and dumbcane all belong to the same plant family and contain the same calcium oxalate crystals. If you’re choosing new plants for a home with dogs, check the ASPCA’s toxic and non-toxic plant database before buying. Spider plants, Boston ferns, and African violets are popular options that pose no risk to dogs.
