9 common houseplants that are toxic to dogs, according to experts — plus 7 safe bets

It only makes sense that you would want to keep your children safe, happy and healthy — we’re talking about dog and plant children here. Unfortunately, though, sometimes the two just don’t mix. Instead of just winging it and filling your home with all the greenery your heart desires, it’s important to learn what plants are toxic to dogs. The reality is that you can’t bet on your dog ignoring your plants (especially puppies), and it’s always better to be safe than sorry.

"All plant material has the potential to cause gastrointestinal upset if ingested," explains Dr. Anna Walker, DVM, a veterinarian at the Veterinary Emergency Group in Larkspur, Calif. However, a handful of common houseplants can cause issues like diarrhea, vomiting, dehydration and damage to the kidneys and other organs.

According to Michael Clarke, a horticulture expert and the founder of Yardwork, the main culprits are the insoluble calcium oxalate crystals and saponins found in certain plants. "These compounds act as a defense mechanism for the plants to deter animals from eating them," explains Clarke.

In terms of just how toxic these plants are, that depends on a few things. According to Dr. Liza Cahn, DVM, a veterinarian and consultant at Embrace Pet Insurance, the severity depends on what plant was consumed, how much was ingested and the length of time before you get to the vet. It also depends on the specific breed, size, age and overall health of your dog. No matter what, though, seek help immediately.

"If your pet eats a toxic plant, time is of the essence," explains Cahn. "Contact your vet or an emergency facility immediately. Be sure to take pictures or bring samples of the plant to the vet." It’s important to note that sometimes symptoms might appear later, so it’s crucial to speak with a medical professional if you think your dog has ingested toxic houseplants, even if they seem fine.

So, what are some of the usual suspects? Dog owners should avoid certain greenery, including snake plants, aloe, pothos and monstera — yes, even though they look so good in your space. And when it comes to flowers, avoid bouquets with lilies, daffodils, azaleas and tulips.

Unsafe houseplants for dogs

Snake Plant

Even though they’re an excellent way to naturally purify the air in your home and they look cool with those spindly, indestructible leaves, snake plants are not it when it comes to pets. Why? They can cause nausea, vomiting and diarrhea.

Aloe vera

Yes, it’s a healing powerhouse for us, but it's the exact opposite for your dog. Symptoms include vomiting, diarrhea, tremors, loss of appetite and lethargy. It can also cause significant distress and dehydration. Yikes, that’s a lot. Honestly, just keep it out of your home — and make sure that aloe gel in your fridge stays out of reach.

Peace lily

Don’t be fooled by the name and gorgeous looks — a peace lily is anything but peaceful for your dog. It contains insoluble calcium oxalate, which can irritate your dog’s mouth and digestive tract. Some symptoms to look out for include excessive drooling, pawing at the mouth, vomiting and swelling or burning of the mouth and lips, all of which can make it hard for them to breathe.

Devil’s ivy (pothos)

Unlike the peace lily, it makes sense that a plant like devil’s ivy (aka pothos) would be a no-go when it comes to keeping your dog safe. Like the peace lily, though, these plants contain insoluble calcium oxalates that irritate the mouth and GI tract.

Philodendron

While the leaves look pretty cascading out of the planter, the forever-popular philodendron can cause major issues thanks to the insoluble calcium oxalates. Like with other toxic houseplants on this list, keep an eye out for vomiting, mouth and throat swelling, excessive drooling and general oral discomfort.

Monstera

The iconic and fun Swiss cheese plant is a staple in any and every modern home (especially since it’s so easy to take care of). However, this kind of cheese should be kept far away from your dog thanks to, again, the insoluble calcium oxalates, which can irritate the mouth and GI tract, leading to uncomfortable swelling and vomiting.

Sago palm

While all parts of the sago palm are toxic, it’s the seeds that are the worst. The seeds (which, according to Walker, tend to be what dogs consume) contain high amounts of cycasin toxin. If ingested, the toxin can cause liver failure and death.

Jade plant

Ingesting any part of the jade plant can lead to vomiting, diarrhea and lethargy. And while it’s more common in cats, it can also lead to neurological symptoms, including tremors, loss of coordination and depression.

Dracaena

Commonly known as dragon trees and ribbon plants, dracaenas are a great beginner-friendly plant. However, it contains saponins. This can cause bloody vomiting, excessive salivating and depression.

Reminder: If you suspect that your dog has eaten a poisonous plant, contact your veterinarian or take them to the emergency room as soon as possible. If you still have concerns about which plants are safe for your dog-friendly home, take a look at the ASPCA’s list of toxic and nontoxic plants. (They also provide lists for cats and horses.)

Don’t worry, though, it’s not all doom and gloom when it comes to your dog and greenery. There are still a slew of fan-favorite plants out there that are safe for your pups — and they’re pretty to boot. Below, find some nontoxic and safe plants for dogs to liven up your space (and a few pretty pots and planters to dress ‘em up).
