28 Toxic Plants for Dogs in your Home and Garden
It's important to understand that toxic plants can be problematic for dogs. Dogs are surprisingly sensitive to different types of plants, and often become ill from exposure. If you live with a dog, the question you should be asking is: "What plants contain chemicals that are toxic for my dog?" We’ve all heard about the dangers of “toxic” plants, but what are the potential hazards of these plants in your home? And why should you avoid keeping these plants in your home? There are a remarkable number of plants that are toxic to your dogs, both indoor and outdoor types. Although some are more dangerous than others, it helps to be alert and maintain your house and yard pet-friendly by keeping hazardous plants out of reach of your furry friends.
In this article, we'll look at some common hazardous plants in your home and garden and their effects on dogs, some of which are more harmful than others. Here is a list of plants that you should avoid keeping in your home or garden.
List of Toxic Plants
1. Aloe vera: Aloe vera includes poisonous properties such as saponins and anthraquinone glycosides, which are purgatives and can cause vomiting and diarrhoea when consumed. When consumed by dogs, aloe vera, which has many beneficial medical properties for humans, can be highly hazardous. Aloe is a succulent species native to Western Asia that is cultivated for medical and agricultural purposes all over the world. Aloe vera is a low-maintenance plant that propagates readily, making it a popular houseplant. Although Aloe vera is safe for humans, it is toxic to dogs and can induce symptoms like lethargy, vomiting, and gastrointestinal problems.
2. Tomato plant: Keep your pets away from your vegetable garden if you're planting tomatoes. The ripened fruit is safe, but the plant's green parts contain solanine, which is harmful to dogs and cats. However, severe poisoning can only happen, if it is consumed in large amounts.
3. Chives: This edible plant, like tomatoes, is toxic to cats and dogs. Chives are a member of the Allium family (onion, garlic, and leeks), which is harmful to cats and dogs because onion and garlic poisoning causes red blood cell destruction. Planting pungent herbs like rosemary and sage, which have a distinct odour, will keep pets out of the garden.
4. Garlic and onion: Toxic components in garlic and onions (allium species) comprise n-propyl disulfide. The allium family of plants, which includes garlic and onions, is toxic to dogs. Ingesting significant amounts of any plant in the allium family can cause hemolysis, a severe reaction in the bloodstream in which huge numbers of red blood cells are destroyed. Severe weakness, fast breathing, and red-colored urine are the final effects. Forced vomiting by a veterinarian is critical in this situation, and many dogs will need blood transfusions to replace damaged blood cells in order to survive.
5. Cactus: The majority of cactus species are grown as attractive houseplants. Because of their thorns and spikes, most plants in this family are toxic and pose a risk to domestic pets. Cactus species contain a variety of harmful chemicals. Spikes also are a danger to your dogs. While most cacti plants aren't dangerous to your dog, the chemical composition of cacti sap can cause stomach problems in your pup. Vomiting, diarrhoea, appetite loss, stomach pain, increased salivation, and nausea are all symptoms of cactus intake in dogs.

Corn plant poisoning in pets can cause vomiting, depression, malnutrition, and hypersalivation, according to the ASPCA. You may detect blood in your dog or cat's vomit if it chewed on a corn plant. Animals with dilated pupils, particularly cats, may be intoxicated by maize plants. If you suspect your pet has eaten the leaves of a corn plant or any other hazardous item, contact a veterinarian.
7. Caladium Plant: Caladiums are houseplants that have heart-shaped leaves that resemble wings. Some people refer to this plant as having angel wings or the heart of Jesus. Your dog may be poisoned by this plant. The caladium plant, which contains an insoluble calcium oxalate acid, causes caladium poisoning. Crystals of calcium oxalate seep into the tissues of your dog's skin and mouth, causing harm to the mouth. Caladium poisoning is characterized by pawing at the face and mouth, vomiting, foaming, and drooling. Swelling of the lips, tongue, and upper airway can cause breathing problems and swallowing difficulties. If you do not get medical attention right once, your dog may perish. The liquid or oils inside the leaves and stem can potentially cause a toxic reaction in your dog's skin and eyes, as well as cause puncture wounds from the thorns.
8. Chrysanthemum: This plant produces pyrethrins, a natural pesticide that repels pests and which are used in insecticides and dog flea and tick treatments. If consumed, all components of the chrysanthemum plant are harmful to pets. Vomiting, diarrhoea, excessive salivation, coughing, appetite loss, irritability, and lack of coordination are some of the symptoms. This plant is poisonous to cats as well.

If any portion of the plant is swallowed, it is harmful to dogs and cats, however, the hazardous feature is unclear.
11. Rubber Tree: Compounds present in the sap of the rubber tree and weeping fig tree (Ficus Benjamina), such as psoralen, or ficusin, can destroy DNA in cells. The term "rubber tree" refers to a variety of plants, some of which are harmless to dogs and others of which are severely hazardous. Fortunately, none of the rubber tree plant species are toxic, however, several forms should be avoided. Dogs are poisoned by some rubber tree plants. Some pets experience nausea, depression, and slower heart rates after consuming the Japanese rubber plant (Crassula arborescens), also known as the jade plant, jade tree, or Chinese rubber plant. The Indian rubber tree (Ficus Benjamina), often known as the weeping fig tree, causes vomiting when eaten and severe skin irritation when it comes in contact.

This plant, however, is harmful to dogs, so you should keep it out of your home. All Cycad plants, including the sago palm, are exceedingly poisonous. These plants include cycasin, a poisonous chemical that causes cancer in mammals, as well as a neurotoxic glycoside (or nerve-poisoning plant sugar) and a carcinogen. Though some dogs like chewing on cycad plants, the leaves, trunk, roots, and seeds of the sago palm plant are exceedingly hazardous. Its growing leaves and reddish seeds are particularly deadly; in fact, even a single seed might be lethal to your pet. The sago palm causes severe vomiting, diarrhea, and gastrointestinal pain in dogs, as well as stumbling, tremors, seizures, and trouble with temperature regulation.
13. Golden Pothos/Money Plant: Another dangerous plant for dogs is the winding, ivy-like golden pothos, which contains insoluble calcium oxalates, which are glass-like crystals that can cause severe irritation when ingested. Insoluble calcium oxalates are a poisonous component of golden pothos. Oral itching and irritation are two of the most common symptoms, and they can sometimes escalate to severe burning and pain in and around your pet's mouth. Excessive drooling, vomiting, and difficulty swallowing are all possible side effects.
14. Peace lily: Toxic properties of Peace Lily include insoluble calcium oxalates. This plant gives your dogs everything except peace.

Easter, day, Asiatic, Japanese display, and Tiger lilies are all deadly varieties of lilies.
15. Lily: Depending on the kind, lilies might be hazardous to pets. If swallowed, calla, peach, and Peruvian flowers are less poisonous, eliciting mild symptoms such as drooling or mouth irritation. Others, such as Asiatic, Easter, and tiger lilies, are more dangerous, having toxic properties found in all sections of the plant, but particularly concentrated in the bulbs. Because dogs are known to dig bulbs out of the ground, it is recommended that bulbs be kept out of reach of their curious paws. Pollen or water from a vase, for example, can induce poisoning in cats. Even one bulb can cause severe intestinal distress, with symptoms such as diarrhoea, dehydration, drooling, vomiting, and drowsiness. Pets can develop a bloated abdomen, jaundice, shock, cardiac imbalance, organ failure, and death in extreme circumstances.
16. Dumb Cane: Dieffenbachia, or dumb canes, are beautifully variegated tropical plants that range in size from less than a foot tall to four to five feet tall, depending on the type.

The plant, although appealing, contains oxalate crystals and other dangerous enzymes that induce a burning sensation when pets chew on the leaves or stems. If swallowed, Dieffenbachia is harmful to both cats and dogs. It includes toxic calcium oxalates that are insoluble. Dieffenbachia poisoning causes oral inflammation and swelling, excessive drooling, vomiting, and breathing difficulties.
17. Oleander: The toxic component of oleander (nerium oleander) is cardiac glycosides. Oleander is a poisonous plant for dogs that is noted for its white or pink flowers and height that gives privacy between yards. If swallowed, dogs can show symptoms like Excessive salivation, abdominal pain, vomiting, diarrhoea, and lethargy.

Supportive therapy with medications that reduce gastrointestinal symptoms.
18. Morning Glory: The poisonous components of morning glory are known as indole alkaloids. When dogs eat the seeds of some varieties of this flowering plant, they can get poisoned. Morning glory seeds contain lysergic alkaloids, which are poisonous to dogs. Ipomoea violacea and Ipomoea carnea are two types of morning glory that are extremely poisonous to dogs. When dogs consume huge amounts of seeds, the many lysergic alkaloids induce suffering. It can cause vomiting, nausea, pupil dilatation (mydriasis), hallucinations, incoordination, diarrhoea, anaemia, disorientation, and liver failure. If you suspect consumption, contact your veterinarian or an emergency veterinary hospital right away.

Lycorine, an alkaloid found in these flowers, can cause vomiting, diarrhoea, stomach pain, and even cardiac abnormalities. The bulbs, on the other hand, have the highest concentration of lycorine, making them the most deadly. Calcium oxalates, which are small needle-shaped crystals that inflict acute discomfort in the mouth, tongue, lips, and throat, are also found in the bulbs and flowers. They might cause stomach pain and vomiting if consumed. Daffodil poisoning can cause difficulty swallowing, significant cardiac arrhythmias, and respiratory distress in dogs, so contact your veterinarian or an animal hospital or clinic if you suspect your dog has eaten any part of the daffodil or bulbs.
