Pets bring immense joy and companionship to our lives. As responsible pet owners, it is crucial to ensure their safety and well-being at all times. One potential danger that pet owners need to be aware of is the ingestion of toxic plants. Pets can be curious creatures and may unknowingly nibble on plants that could be harmful to them. In this article, we will discuss the symptoms of plant poisoning in pets, focusing on dogs and cats, and provide essential information for pet owners to keep their furry friends safe.

Recognizing the Symptoms

When a pet ingests a toxic plant, it is essential to be able to recognize the symptoms of plant poisoning. The signs can vary depending on the specific plant ingested, the amount consumed, the size and age of the pet, and their overall health. Here are some common symptoms of plant poisoning in pets:

  1. Gastrointestinal Issues: Vomiting and diarrhea are the most common symptoms associated with plant poisoning. Pets may exhibit frequent episodes of vomiting and have loose, watery stools.

  2. Drooling and Excessive Salivation: Pets may experience increased drooling and excessive salivation when they have ingested a toxic plant. This can be accompanied by a foul odor from the mouth.

  3. Oral Irritation: Some plants contain irritating substances that can cause discomfort in the mouth, throat, and esophagus. Pets may paw at their mouths, exhibit signs of oral pain, or refuse to eat.

  4. Dehydration: Severe vomiting and diarrhea can lead to dehydration in pets. Signs of dehydration include lethargy, sunken eyes, dry gums, and decreased skin elasticity.

  5. Neurological Symptoms: Ingesting certain toxic plants can affect the central nervous system of pets. This can manifest as tremors, seizures, disorientation, weakness, and loss of coordination.

  6. Respiratory Issues: Breathing difficulties, coughing, wheezing, and labored breathing can occur after ingestion of certain toxic plants. This can be a result of respiratory tract irritation or edema.

  7. Skin Irritation: Contact with certain plants can cause skin irritation, rash, redness, and blisters in pets. It is essential to be cautious about plants that may irritate the skin upon contact.

  8. Cardiovascular Symptoms: In severe cases of plant poisoning, pets may exhibit irregular heartbeats, racing heart, palpitations, and even heart failure. These symptoms require immediate veterinary attention.

It is important to note that the severity of the symptoms can vary depending on the specific plant and the amount ingested. Some plants are more toxic than others, and even a small amount can cause severe symptoms, while others may only result in mild gastrointestinal upset.

Common Toxic Plants for Pets

To prevent plant poisoning in pets, it is crucial to be aware of common toxic plants that pose a risk to their health. Here are some examples of plants that are toxic to dogs and cats:

  1. Lilies: Both Asiatic lilies and daylilies are toxic to dogs and cats. Cats are more severely affected, experiencing acute kidney injury or death even with a small exposure. Dogs usually show signs of stomach upset, but ingestion of bulbs can cause blockages.

  2. Azaleas and Rhododendrons: The effects of these plants on pets vary depending on the amount ingested. Large ingestions can lead to severe symptoms like irregular heartbeats and seizures, while small ingestions typically result in mild stomach upset.

  3. Sago Palms: Highly toxic to small animals, sago palms can cause severe symptoms such as vomiting, diarrhea, difficulty clotting blood, liver failure, and even death. The seeds or nuts are the most toxic parts.

  4. Tulips: Consumption of tulips can cause stomach upset, and ingestion of large bulbs may lead to blockages.

  5. Hydrangeas: Hydrangeas contain cyanide, but it is uncommon for small animals to experience cyanide poisoning. Dogs and cats usually only show signs of stomach upset.

  6. Peace Lilies: Peace lilies can cause mild symptoms like stomach upset, drooling, and mouth pain due to insoluble calcium oxalate crystals. Severe signs are unlikely.

  7. Devil’s Ivy (Pothos): Similar to peace lilies, devil’s ivy can cause mild stomach upset. Medical attention is usually unnecessary unless the upset becomes severe.

  8. Lantana: While rare, ingestion of lantana can lead to liver failure in cats and dogs. Stomach upset is the most common symptom.

  9. Daffodils: Daffodils can cause stomach upset, and if large chunks of the bulbs are eaten, they may cause blockages or low blood pressure.

  10. Hostas: Hostas can cause mild stomach upset in pets, and veterinary care is typically not required unless symptoms are more severe.

It is crucial to research and identify plants commonly found in and around your home to ensure they are safe for your pets. Being aware of the toxic plants in your environment can help you make informed decisions when choosing plants for your garden or indoor spaces.

Immediate Actions for Plant Poisoning

If you suspect that your pet has ingested a toxic plant, it is important to take immediate action to ensure their safety. Here are the steps you should follow:

  1. Remove the Source: If you witness your pet eating a plant or suspect plant ingestion, remove the plant from their reach to prevent further consumption.

  2. Contact a Veterinary Professional: Call your veterinarian or an emergency animal poison control hotline for guidance. Provide them with detailed information about the plant, the amount ingested (if known), and your pet’s symptoms.

  3. Observe and Monitor: Keep a close eye on your pet’s behavior and symptoms. If their condition worsens or you notice any severe symptoms, seek immediate veterinary care.

  4. Preserve Evidence: If possible, save a sample of the plant in a sealed bag or container for identification purposes. This can help the veterinarian identify the toxin and provide appropriate treatment.

Remember, it is always better to err on the side of caution when it comes to plant poisoning. Even if you are unsure whether the plant is toxic or not, seeking veterinary advice is crucial.

Prevention is Key

Preventing plant poisoning in pets is the best approach. Here are some preventive measures you can take to keep your pets safe:

  1. Research Plants: Before bringing a new plant into your home or planting in your garden, research its toxicity to pets. Consult reliable sources or your veterinarian for a comprehensive list of pet-safe plants.

  2. Proper Plant Placement: Keep toxic plants out of your pets’ reach. Place them in areas that are inaccessible to your pets, such as tall shelves or hanging planters.

  3. Supervise Outdoor Activities: If you allow your pets to roam in the yard or garden, closely supervise them to ensure they do not ingest any toxic plants. Consider using fencing or barriers to create designated pet-friendly areas.

  4. Educate Pet Sitters and Visitors: Make sure anyone who interacts with your pets, such as pet sitters or house guests, is aware of the potential dangers of toxic plants and knows to keep them away from your pets.

  5. Consider Safe Alternatives: If you have a cat that enjoys chewing on indoor plants, consider providing safe alternatives, such as “cat grass,” which is specifically grown for feline consumption.

By taking these preventive measures, you can significantly reduce the risk of plant poisoning in your pets and create a safe environment for them to thrive.


As pet owners, it is our responsibility to ensure the well-being and safety of our furry friends. Recognizing the symptoms of plant poisoning in pets is crucial to providing timely and appropriate care. By familiarizing yourself with common toxic plants, taking immediate action in case of ingestion, and implementing preventive measures, you can protect your pets from the hazards of toxic plants. Remember, when in doubt, contact your veterinarian for professional advice and guidance.
