It can be hard to balance the love for plants and dogs, and although you might want to get your house looking green and full of plants, some are off-limits for dogs. While most dogs instinctively know to avoid poisonous plants, which is a miracle in itself, it is still good to be on the safe side of things. 

Having plants around brings tremendous benefits and it is no myth. They are perfect for aesthetics but also enhance your well-being. By purifying the air, absorbing moisture, or just for your general feeling, plants in your home bring positivity and relaxation. Although they are a beautiful addition all day, every day, and everywhere, you might want to watch out for these ten if you have dogs.

10 Houseplants That Are Poisonous to Dogs

Most dogs understand these ten plants are not to be approached instinctively. However, if you want to be certain and keep them secure at all times, you can substitute various types of plants for your dogs' happiness, safety, and long-term companionship.

1. Aloe Vera

Although this is a very common houseplant that the majority of the plant-loving population has at home and has some parts that are safe for dogs, it's better to keep them away from your four-legged friends. Aloe vera is considered among the houseplants that are poisonous to dogs because chewing on the plant can expose a dog to toxins called anthraquinone glycosides, which can cause diarrhea and vomiting.

Alternative: The Haworthia, also known as the zebra plant will keep your dog safer, besides that you’ll practically get a very similar soft spiny look without the toxicity risks.

2. Ivy (Including English Ivy and Others)

Although ivy plants may look stunning tumbling out of a wall or garden, they are not among the best suited to have around your dog. Various ivy varieties are considered houseplants that are very poisonous to dogs because of several toxins the plant contains. Triterpenoid saponins and polyacetylene compounds will cause excessive drooling, vomiting, diarrhea, and abdominal pain if your dog chews on a leaf.

3. Jade Plant (Crassula Ovata)

Another houseplant that is poisonous to dogs is the jade plant. This rubber-like type of plant is known to cause vomiting and a slow heart rate, in addition to a harder-to-identify symptom that involves great sadness and depression. Make sure to keep it away from your dog to avoid chronic health problems and keep them smiling joyfully every day.

Alternative: The Christmas cactus is a beautiful, pumped, red cactus that is very easy to care for, plus in ideal conditions, you’ll see more good growth and a yearly set of red or bright pink flowers. A much better option than the jade plant if what you're looking for is safety for your doggo.

4. Dieffenbachia

Why is this houseplant considered poisonous to dogs? Simply explained, the leaves of this specific plant, a.k.a 'leopard lily' contain tiny, sharp calcium oxalate crystals that can easily irritate a dog’s mouth and cause severe swelling and burning of the mouth and tongue.

5. Philodendron Species

Just like the Dieffenbachia plant, all Philodendron species have very similar consequences for your dog if chewed or swallowed. Make sure to keep them away from this type of plant, given the fact that the calcium oxalate in the leaves can irritate a dog’s mouth, resulting in swelling, burning, and occasionally difficulty breathing. (There are more than 50 species of Philodendron that can be poisonous to dogs).

Alternative: The  Areca Palm houseplant is a much better alternative and lets you live your days stress-free. No worries, you'll be able to keep the tropical vibes aligned when you replace your philodendron. With proper care, you can expect an areca palm to reach a height of 1.8-2.1 meters (6 to 7 feet) and live for up to a decade.

6. Sago Palm (Cycas Revoluta)

Pay close attention to this one, as it is known to be one of the 10 most poisonous houseplants to dogs, all the way from the seeds and roots to the leaves. The toxin cycasin can cause vomiting and diarrhea, and in severe cases, the toxicity can even result in seizures, lethargy, and liver failure. Better take it out of your house!

Alternative: A Chamaedora Elegans, a.k.a. Parlor Palm grows upright and brushlike. You can count on it to stay roughly the same size, making it a fun and predictable creative plant for you to explore.

7. Asparagus Fern

Similar to other houseplants that are poisonous to dogs, the Asparagus Fern also makes the list for sure. Unfortunately, asparagus ferns carry a toxin that can cause vomiting and diarrhea if ingested, along with skin irritation if your dog is exposed to it repeatedly.

Alternative: Boston ferns (Nephrolepis exaltata) are pet-safe, proven, and studied by veterinarians and plant lovers. If you give them the correct type of lighting, food, watering, and temperatures, these plants are very easy to care for and will thrive as houseplants.
