Common Outdoor Plants That Are Poisonous To Dogs

Are you a person who loves to bring plants to your garden so often? It’s a satisfying hobby to see your babies growing and getting bigger day by day. For an avant-garde gardener like me, there are numerous species of plants including exotic ones to deal with. But do you know some plants are poisonous to dogs and are also capable of even killing your buddy? 

Some Harmful And Poisonous Plants For Dogs

I’m going to list out the most common dangerous plants in this article so that you can stay assured that your dog won’t harm himself by ingesting any part of the plants.

Tomato Plant

The first on our list are those juicy red tomatoes. Unfortunately, tomato plants are poisonous to dogs. They belong to the deadly nightshade family. You might’ve seen dogs enjoy eating tomatoes and never seen them being sick due to that. 

This sounds contradictory to what I’m saying. In fact, raw tomatoes and other parts of the plants are the ones causing the problem. Dogs who ingested any parts of a tomato plant may experience drowsiness, weakness, gastrointestinal problems, slow heart rate, and confusion.

Sago Palm

This cute and delicious looking plant to your dog can be a threat for her. You know how curious and frenzy a dog goes when she’s in a play mode. Sago palm is one of the most popular ornamental plants in places with warmer climates. All parts of the plant are toxic for dogs. Side effects of ingesting this plant include liver failure and even death. Please make sure you don’t have this plant in the surroundings.

Aloe Vera

Aloe Vera is a succulent and quite common outdoor plant across the world. Anna Louis from Doglovesbest says, “The medical and health benefits this plant offers is incredible and because of that we often miss out on the fact that the plant is potentially harmful to dogs.”

Saponins in most succulent plants can cause diarrhea, vomiting, tremors, lethargy, and general nervous system depression.

Ivy 

Some Ivy plants like English Ivy and Devil’s Ivy/Golden Pothos have moderate toxic effects on dogs. Side effects of eating the parts of the plant include excessive salivation or drooling, diarrhea, vomiting, swelling of the mouth, tongue, and lips, and abdominal pain.

Amaryllis

This plant with beautiful flowers will catch your attention at nursery but be wary of its harmful effects on dogs. Not to mention, it is quite a common garden plant. Also, if you have indoor plants, ensure that all of the flower ones are safe for pets.

Lilies

Unfortunately, yes, those beautiful flowers are highly toxic to pets. These plants are potentially fatal for felines but some of them are toxic to dogs as well. It’s a no-no to have these plants around your house. 

Potential threats of ingesting lilies include depression, difficulty swallowing, lowered appetite, vomiting, diarrhea, kidney failure and damage, and sometimes even multiple organ failure.

Cannabis

Cannabis, being legal for pets in the form of CBD doesn’t mean it’s not harmful to your pets. Cannabis poisoning is a potential threat to your dog if you have the plants in your garden or any plant leftovers present around dogs.

Here are some signs indicating the ingestion of cannabis in dogs: drooling, incoordination, tremors, seizures, possible respiratory problems, depression, coma. In addition, Delta nine tetrahydrocannabinol can affect your dog’s neurological system.

Gladiola

Also known as ‘sword lily’, this plant is dangerous to dogs. The side effects include vomiting, diarrhea, exhaustion, and drooling.

American Holly

With the scientific name Ilex opaca, this American native shrub is commonly found outdoors. If you have unknown plants in your dog’s reach, you would want to check for American Holly as well.

The common side effects of eating this plant are vomiting and diarrhea. Ethan from Catlovesbest advises people to be wary of this plant, “This plant is comparatively low toxic but because of its ubiquity, it has a potential to make your canine pal sick.”

Daffodil

A bulb-forming plant in the amaryllis family, Daffodil is cultivated for the flowers. You can easily find this flower-plant in nurseries. Dogs can feel low blood pressure, intestinal spasms, high drooling, tremors, diarrhea, vomiting, and in some cases, cardiac arrhythmia.

Baby’s Breath

You might not have seen Baby’s Breath plants but their flowers can be easily found in almost every bouquet. This plant with tiny white flowers is harmful to your dogs and can cause diarrhea and vomit.

Milkweed

Asclepias, with a common name, milkweed, is dangerous for dogs. This plant is native to the United States and Canada. This very commonly seen plant is deadly. On ingesting it, dogs may experience usual diarrhea and vomiting but in some cases, it can cause difficulty breathing, liver or kidney failure, dilated pupils, rapid and weak pulse, and even death.

Tulip

Tulips are loved across the globe. But again, this plant is harmful to your pooch and you need to ensure your dog doesn’t have its way around this plant. Dogs may feel normal gastrointestinal problems on ingesting and some severe cases include central nervous system depression, convulsions, and death.

Lantana

These plants can be seen in many countries across the world. It is also known as a weed in Australia. Lantana is colorful but extremely dangerous for pets. The toxication signs are vomiting, weakness, diarrhea, depression, abdominal swelling, loss of appetite, shock, paralysis, and in some cases, liver failure.

Asparagus Fern

This plant is known as an emerald feather and lace fern. The toxicity in dogs of this plant is from mild to moderate. The side effects include vomiting, diarrhea, abdominal pain, excessive drooling, and allergic dermatitis.

The End Note

I have listed about 15 toxic commonly found plants in the garden. If you’re getting a dog, please check your garden and surroundings for these plants and immediately remove them. Moreover, some of these plants are often gifted as flowers so they may end up in your house. Please watchful for that to keep your dogs happy and safe.
