To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
5 Common Poisonous Plants For Dogs
Aloe Vera is probably one of the most common household plants. These plants don’t require much maintenance. They CAN be very beneficial for us as pet owners.
Externally, aloe has many benefits to dogs. These benefits include:
However, aloe contains certain properties that can be a problem. These exist in the aloe latex, the yellow sappy part under the rind. This latex contains a natural chemical called aloin. In large enough quantities, aloin can irritate the intestines and cause electrolyte loss.
- Mild to Moderate
- Changes in color of urine
- Tremors (which is rare)
- Anorexia (or loss of appetite)
Elephant ears belong to the Araceae family. These plants are filled with calcium oxalate crystals that are insoluble. Any time this plant is chewed on or bitten into, crystals are released.
These crystals get into tissue and will irritate the mouth and gastrointestinal tract. In rare cases, the upper airway will become swollen. This makes breathing extremely difficult.
- Mild to moderate
- Pawing or messing with their mouth
- Oral pain
- Loss of appetite
Poinsettias are a popular plant, especially during the holiday season. Their lush, red leaves make the perfect decoration. But these plants have a bad reputation, and when it comes to our dogs, it isn’t undeserved.
If your dog eats them, poinsettias can give generally mild signs of illness. When exposed to the skin, the milky sap of this plant can cause irritation, swelling and itchiness.
- Licking lip
- Skin irritation, redness, swelling or itchiness
- Eye irritation
Yes, tomatoes! Many of us like to grow our own plants, herbs and vegetables. And that usually includes tomatoes.
Now, let me be clear when I state that the tomato itself is not poisonous to your dog.
However, those beautiful green, leafy vines that the tomatoes grow on are. Those contain a property called solanine. This is found in many other plants from the Solanaceae family.
Solanine is only found in the green parts of the plant. For this to cause severe poisoning for your dog, she would need to ingest a lot of it. But even some ingestion of this plant can cause severe gastrointestinal issues.
Iris is a common plant used in household gardens. It’s also known as the bearded iris, snake lily, yellow flag, yellow water iris or Western blue flag.
And although they’re not likely to cause death, they can cause issues if they’re eaten or touched. Irritation can occur just from handling or touching these plants.
Most of the compounds that cause irritation are the most potent in the bulb of the plant.
- Mild to moderate
When we first published this post, we got a lot of questions about other plants, so we thought we’d add to the list.
Here are more plants that are toxic to dogs:
Just as there are many poisonous plants for dogs, there are a few alternatives that are completely safe! If you want to avoid the ones above, here are a few good ones that not only look beautiful, they have some great benefits.
Not only is it pretty to look at, this plant is completely harmless to your dog. In fact, this plant has many health benefits. If your dog happens to eat them, she’ll reap the benefits!
Here are just a few of the benefits of basil:
This flower is part of the sunflower/daisy family (Asteraceae). If you enjoy flowers in your garden and around your house, the African daisy is a safe alternative. These flowers are bright and yellow in color. They pose zero threat to your dog if she decides to eat them for a snack.
This is another low maintenance plant which is very easy to grow. They offer perennial color without potentially threatening your dog’s health.
Just pay attention when you’re shopping for lilies. There are MANY types of lilies that are highly toxic to dogs and cause serious danger for cats, including:
One great thing about the spider plant is it’s safe for ALL PETS. We all know dogs love to eat things, whether they’re harmful or not. The spider plant is no exception to this rule.
Dogs tend to be very fond of the taste of these plants and are likely to chew or eat them. However, this is a better alternative because of their non-toxicity.
Note: If your dog ingests enough of the spider plant, it can cause vomiting. However, this is more of an upset stomach issue rather than a toxic reaction.
This is by no means an all-inclusive list of plants poisonous to dogs. For a more extensive list of nearly 400 plants, visit the ASPCA website. Toxic plants should be eliminated from your home or closely monitored so your dog is unable to access them. Food plants that are toxic to your dog should be securely fenced so your dog cannot get near them if they cannot be removed from your landscape. If you suspect that your dog has eaten something he shouldnt, call your vet immediately or call the ASPCA emergency poisoning hotline at 1-888-426-4435. Related & Popular
If you have a puppy or an inquisitive adult dog, you know that your pet is not very picky about what he puts in his mouth. This can be very dangerous if the dog decides to chew on something poisonous. Most people know to keep chemicals away from their pet, and many are aware of the potential dangers of chocolate for dogs, but do you know that many common houseplants and landscape plants like gardenias and geraniums are deadly?

Though many dog owners have been told to keep their pets away from colorful plants because theyre inevitably dangerous, this isnt necessarily true. Petunias, for example, are beautiful flowers that arent toxic to dogs. Cannas – frequently referred to as “Canna Lily” though not truly a lily – is also considered non-toxic to dogs. Of course, this doesnt mean dogs should be fed these plants intentionally, but rather that pet parents shouldnt panic if their dog happens to grab a bite of either of these colorful plants.
Every dog owner should have a list of plants poisonous to dogs in order to protect their canine companion from illness or death. There are literally hundreds of plants that would belong on such a list, but the following are a few of the most common.
If youre partial to lilies, you have a few other options for your garden, in addition to the canna. Stargazer lilies (Lilium orientalis) are not only beautiful but they carry a delicious fragrance. Tiger lilies (Lilium tigrinum), red lilies (Lilium umbellatum), Easter lilies (Lilium longiflorum), day lilies (Hemerocallis), and rubrum lilies (Lilium speciosum) are other dog-friendly choices for your yard. Though Pal wont suffer if he nibbles those lilies, theyre toxic to cats, causing reactions ranging from lethargy and vomiting to kidney failure. If Pal has a feline friend outside, the sand lily (Leucocrinum montanum) is a beautiful choice thats nontoxic to cats and dogs.
If you catch Pal noshing on a lily, keep an eye on him even if its on the nontoxic list. He may experience an upset tummy from ingesting the greenery, similar to the effect he may feel when he eats grass. If he gets hold of one of the toxic lilies, get him and the plant to the vet. The vet will determine appropriate treatment, such as whether to induce vomiting or administer activated charcoal to decontaminate your pup. Early treatment improves his prognosis.
Canna lilies (Canna generalis) are beautiful flowers, adding bright splashes of red, orange and yellow to your garden. Available in dwarf and regular varieties, they can provide interesting architectural elements to your garden, too, ranging from as small as 30 inches tall to as large as 8 feet tall. Regardless of the size or color you choose, you can rest easy if you go with this summer bloomer. The ASPCA lists canna lilies as nontoxic to dogs, so if Pal takes a bite, hell be fine.
The peace lily, or Spathiphyllum, isnt so peaceful for Pal. Its toxic effects can cause irritation in his mouth, intense burning, difficulty swallowing, excessive drooling and vomiting. The pretty lily of the valley (Convallaria majalis) isnt pretty for any pup, potentially leading to vomiting, disorientation, seizures and irregular heart beat. Like the canna, the beautiful calla lily (Zantedeschia aethiopica), isnt really a lily. A member of the Araceae family, it has a similar effect as the peace lily. Use the bright orange color of the fire lily, or Hippeastrum, as caution to stay away: its effects include vomiting and diarrhea. If Pal eats large amounts of this, or gets to the bulb, it can be particularly poisonous, causing low blood pressure, tremors, convulsions and cardiac arrhythmia.
