What houseplants are toxic to dogs? Stay away from these!

My home is brimming with greenery, a usual scenario for plenty of plant lovers. A significant number of these plant enthusiasts also have an affinity for pets, often wishing to have one. Keeping a dog, or perhaps even several dogs, at home is ideal, although there can be a struggle to harmonize one’s affection for both, as they don’t always live together in perfect harmony.

What houseplants are toxic to dogs? The list is extensive. A wide variety of houseplants are toxic to your dogs. Popular houseplants like Arrowhead or Peace lilies, along with many others, can make your dogs ill. In this article, I will cover what houseplants to watch out for.

Of course, you should note that the level of toxicity of these plants and their effect on your dog will vary according to type, how much of the toxins are ingested or inhaled, and the extent of the symptoms the dog may show. This post will address most of your concerns.

Certain plants are not suitable to have around your dogs. They can be toxic to your dog if ingested or even sniffed in some instances. Dogs like to nibble on green things if given enough freedom.

Dogs like sniffing the edges of leaves before they chew, and while they may have a good nose, they don’t always know what toxins are harmful, and they eat green leaves for several reasons: play, boredom, or because they have an upset tummy.

Dogs getting ill is not so common, and even suspecting your plant may be the cause is even less common, so it is always necessary to check your dog to ensure they aren’t playing near any toxic plant.

How to keep your dogs safe from these plants?

With the huge list above, you would be forgiven for thinking you want to rid your house of all plants to keep your dogs safe. However, there are ways to keep your dogs safe and still have plants. Some of those include:

  • Keep plants dogs will not chew on
  • Use a pebble mulch
  • Consider sacrificial plants
  • Move plants to a safer location
  • Hanging plants to keep dogs away
  • Spray plants with a dog deterrent
  • Ensure your dog has toys to occupy itself

Keep plants dogs will not chew on

There are many plants that dogs do not like to eat; these include heavily scented plants like rosemary and spiky plants like cactus; these plants are ideal for keeping around dogs.

Use a pebble mulch

Dogs play with plant pots and soil when they are bored. They love to make a mess by pulling over and chewing plants and soil. Adding large pebbles as mulch to the tops of your pots will help to distract the dogs from the soil below.

Consider sacrificial plants

Why not consider using sacrificial plants? These are plants that dogs like to eat. You could place these in a more accessible place for the dogs to chew on. Consider plants like catnip and lemon balm for these.

Move plants to a safer location.

Although dogs can’t climb around the house, they quickly turn over pots on low levels. You could place your plants in safer locations around the house. High shelving may be out of the dog’s jumping distance or in windowsills blocked for dog access.

Hanging plants to keep dogs away

Even better than just moving your plants, consider hanging them from the ceiling or having a dedicated stand to hang them from. This will keep the dogs away from your plants thoroughly.

Spray plants with a dog deterrent.

Many dog deterrents on the market; make the plants smell unfavorable to them, and therefore, they are left alone. Products such as the following can be used, all with significant effects.

Ensure your dog has toys to occupy itself

With such an array of dog toys on the market, you shouldn’t need your dog to want to chew your plants. The owner is responsible for providing adequate attention-style toys for your dogs. Consider chewing toys and toys that smell like things dogs love

Sometimes we may have both dogs and cats in the same home. If you have both, consider checking out my article What houseplants are toxic to cats? Avoid these Now! Although there are a lot of similarities, there are differences that need to be addressed.


In summary, toxicity may vary depending on the amount of plant ingested or the type of plants, as discussed above. If you want to buy plants for the home, you should first research whether they are toxic to dogs to avoid wasting your money on poisonous plants.

As discussed, many plants are toxic to dogs, and we should also engage with vets just in case we see symptoms like swelling, redness, and itchiness of the eyes, mouth, or skin. Other symptoms may include vomiting, diarrhea, excessive urination, and difficulty breathing.

If treatment is delayed, ingestion may be deadly, while some plants may require a special dog diet. We should remove such toxic plants from home and keep the dog indoors with special supervision to avoid all these.

However, I do not want to prevent you from growing these plants at home. Maybe get rid of your dog instead. ONLY JOKING! But in all seriousness, consider the plants you are growing and their location within the home.
