Common Plants Poisonous To Pets

There are a variety of plants that can be harmful to your pet, whether they’re out in the great outdoors or in your own backyard. This list covers some of the more common plants poisonous to pets, but it’s important to remember that there are other potentially harmful plants out there. If you suspect that your pet has ingested a harmful plant, it’s advised to go see your veterinarian immediately rather than waiting for symptoms to show.

1. Aloe Vera

A plant with a variety of uses, Aloe Vera can be very helpful for humans but not so much for pets. If ingested, your pet can show symptoms such as, but not limited to: Vomiting, diarrhea, change in urine color, and tremors.


2. Azalea

There are over 1,000 species of Rhododendron and the Azalea is one of the better known ones. As beautiful as these flowers can be, they are not to be ingested by pets. As little as .2% of a pet’s body weight can lead to poisoning. Symptoms from eating Azaleas can include but are not limited to, diarrhea, vomiting, abdominal pain, hypotension, tremors, and abnormal heart rate.


3. Baby’s Breath

Often found in floral arrangements, baby’s breath can be a great decoration. Wherever you decide to place them, they should be out of reach of any pets. If ingested, symptoms can include but are not limited to, vomiting and diarrhea.


4. Carnations

Although not as dangerous as an Azalea being nibbled on, Carnations are found in many situations and are more common than one would expect. That being said, it’s still not safe for pets to consume them. Symptoms include, but are not limited to mild stomach problems and mild dermatitis.


5. Chrysanthemums

They’re gorgeous and borderline mesmerizing, it’s no surprise why they’re a common flower. If your pet ends up mistaking these for a toy or snack, symptoms can include but are not limited to, Vomiting, diarrhea, incoordination, and dermatitis.


6. Daffodils

Seen in Big Fish, daffodils are a common, beautiful flower. We wouldn’t advise growing a field of them if you have pets. Symptoms from eating a daffodil can include but are not limited to, nausea, increased heart rate, cardiac arrhythmias, abnormal breathing, vomiting, and diarrhea.


7. Lilies

Although no pet should eat Lilies, cats are especially sensitive to poisoning from this plant in all its forms. If consumed, symptoms can include but are not limited to, lethargy, vomiting, and appetite suppression. Certain species of Lilies are lethal to cats, so take caution if you have them in your garden.


8. Morning Glory

At first glance they look like something you’d see through a kaleidoscope, making it ironic that this flower can cause hallucination in pets. Since they’re so easily available, it’s important to make sure your pet doesn’t eat any. Symptoms can include, but are not limited to: Hallucinations, agitation, stomach issues, tremors, disorientation, and ataxia.

9. Oleander

Often found in warmer climates, Oleander is a dangerous plant for many species. This plant’s naturally occurring poisons (cardenolides or bufadienolides) are ones that affect the heart. If ingested, symptoms can include, but are not limited to: Abnormal heart rate, cardiac arrhythmias, tremors, nausea, and seizures.


10. Tulips & Hyacinths

Both belong to the Liliaceae family and are very similar in that their toxin is very concentrated in the bulb instead of the actual flower. “So I plant the bulb and then it’ gone, so this plant is fine, right?” Not exactly. Dogs have been known to dig up freshly planted bulbs or have even been able to sneak some away while they’re being planted. If the bulb is chewed or eaten, it can result in symptoms such as (but not limited to): tissue irritation in the mouth and esophagus, increased heart rate, diarrhea, difficulty breathing, and vomiting.
