Are English Ivy Plants Toxic to Dogs? Leaf and Berry Dangers

Last updated: May 16, 2026

Is English Ivy Toxic to Dogs?

Yes, English ivy (Hedera helix) is toxic to dogs. Both the leaves and the berries contain triterpenoid saponins and polyacetylene compounds that can cause vomiting, diarrhea, excessive drooling, and abdominal pain. The berries are more concentrated in toxins than the leaves, making them especially dangerous if your dog eats them.

English ivy is one of the most widespread ornamental plants in North America, used as ground cover, climbing wall decoration, and even indoor houseplant. Its hardiness and ability to thrive in shade make it a landscaping favorite, but dog owners should understand the risks it carries. Contact with the sap can also cause skin irritation and dermatitis in some dogs.

Toxic Compounds in English Ivy

English ivy contains two main classes of toxic compounds. The first is triterpenoid saponins, specifically hederagenin and hederin. These chemicals irritate the mucous membranes of the mouth, throat, stomach, and intestines when ingested. They are responsible for the gastrointestinal symptoms commonly seen after ivy ingestion.

The second group of toxic compounds is polyacetylene compounds, including falcarinol and didehydrofalcarinol. These are found primarily in the sap and are the main culprits behind the contact dermatitis that English ivy can cause. When a dog chews on ivy stems or leaves, these compounds can irritate the skin around the mouth and any skin that comes into contact with broken plant material.

The toxin concentration is highest in the berries, followed by the leaves, then the stems. Young, actively growing ivy tends to have higher concentrations of sap and therefore poses a slightly greater risk. However, all parts of the plant at any stage of growth should be considered toxic.

Symptoms of English Ivy Poisoning in Dogs

Symptoms typically develop within a few hours of ingestion and can vary depending on how much your dog ate and which part of the plant they consumed.

Gastrointestinal Symptoms

• Vomiting, which may be repeated
• Diarrhea, potentially with blood in severe cases
• Excessive drooling and salivation
• Loss of appetite
• Abdominal pain or tenderness

Skin and Oral Symptoms

• Redness, swelling, or blistering around the mouth and muzzle
• Skin rash or irritation on areas that contacted the sap
• Pawing at the mouth due to oral discomfort

More Serious Symptoms

In cases where a dog has eaten a large quantity of ivy, particularly the berries, more concerning symptoms may appear:

• Difficulty breathing or labored breathing
• Muscle weakness or tremors
• Excessive thirst
• In very rare and severe cases, coma or paralysis

If your dog shows any breathing difficulties, muscle tremors, or extreme lethargy after eating English ivy, treat it as an emergency and get to a veterinarian immediately.

First Aid Steps for English Ivy Ingestion

Quick action can make a significant difference in outcomes. Follow these steps if your dog has eaten English ivy:

1. Remove your dog from the ivy. Prevent further ingestion and carefully remove any plant pieces from their mouth.
2. Rinse the mouth gently. Use clean water to flush any sap or plant residue from your dog’s mouth and gums. If sap contacted their skin, rinse those areas too.
3. Contact your veterinarian immediately. Describe what your dog ate, approximately how much, and when. Your vet will advise on next steps based on your dog’s size and the amount ingested.
4. Do not induce vomiting at home unless your veterinarian specifically tells you to. The saponins are already irritating the digestive tract, and vomiting could worsen the irritation or cause aspiration.
5. Bring a plant sample to the vet. This helps confirm the identification and allows the vet to determine the appropriate treatment.

You can also call the ASPCA Animal Poison Control Center at (888) 426-4435 for immediate guidance. Keep this number saved in your phone alongside your vet’s emergency line.

Veterinary Treatment for Ivy Poisoning

Your veterinarian will assess the severity of the poisoning and provide supportive care. There is no specific antidote for English ivy poisoning, so treatment focuses on managing symptoms and preventing complications.

Typical treatments include:

• Activated charcoal: Administered early to bind toxins remaining in the stomach.
• IV fluid therapy: To prevent dehydration and support kidney function, especially if your dog has been vomiting or having diarrhea.
• Anti-nausea medications: To reduce vomiting and help your dog feel more comfortable.
• Topical treatments: If contact dermatitis is present, soothing ointments or medicated baths may be prescribed.
• Pain management: For abdominal discomfort or oral irritation.

With prompt treatment, most dogs recover from English ivy poisoning within 24 to 72 hours. The prognosis is good for dogs that receive timely care, and long-term complications are rare.

Preventing English Ivy Exposure

English ivy is so common in both outdoor landscapes and indoor plant collections that preventing exposure requires some deliberate effort. Here are practical strategies:

• Remove ivy from your property. If you have a dog, consider replacing English ivy with pet-safe ground covers like creeping thyme, Irish moss, or dwarf mondo grass.
• Keep indoor ivy out of reach. If you choose to keep English ivy as a houseplant, hang it high where your dog absolutely cannot reach it. Keep in mind that fallen leaves still pose a risk.
• Watch for ivy on walks. English ivy grows on fences, walls, and trees throughout many neighborhoods. Keep your dog on a leash in areas where ivy is present and redirect them if they show interest in chewing on it.
• Check your yard after storms. Wind and rain can break off ivy branches and scatter berries across your lawn, bringing toxic material into your dog’s play area.

English ivy is also an invasive species in many parts of the United States, so removing it from your property benefits local ecosystems as well as your dog’s safety.

English Ivy vs. Other Ivy Species

Not all plants called “ivy” are equally dangerous. Here is a quick comparison:

• English ivy (Hedera helix): Toxic to dogs. Contains saponins and polyacetylene compounds.
• Boston ivy (Parthenocissus tricuspidata): Mildly toxic. Contains oxalates that can irritate the mouth and stomach.
• Swedish ivy (Plectranthus verticillatus): Generally considered non-toxic to dogs by the ASPCA.
• Poison ivy (Toxicodendron radicans): Causes skin reactions in humans but is generally not toxic to dogs if ingested. Dogs can carry urushiol oil on their fur and transfer it to humans.

If you want a trailing or climbing plant that is safe for your dog, Swedish ivy is a good alternative. Always verify the specific species before adding any plant to your home.

If you are preparing your home before adopting a new dog, a thorough plant audit is an essential step in pet-proofing your space.

Frequently Asked Questions

Can a dog die from eating English ivy?

Death from English ivy poisoning is extremely rare in dogs. The toxicity is classified as mild to moderate. However, ingestion of large quantities, particularly berries, can cause severe dehydration from persistent vomiting and diarrhea, which can be life-threatening without treatment. Always seek veterinary care if your dog eats English ivy.

Is English ivy toxic to dogs through skin contact alone?

Yes, the sap from English ivy can cause contact dermatitis in dogs, resulting in skin redness, irritation, and sometimes blistering. This is caused by the polyacetylene compounds in the sap. If your dog brushes against broken ivy stems or crushed leaves, rinse the affected skin with water and watch for signs of irritation.

How much English ivy is dangerous for a dog?

There is no precise toxic dose established for English ivy in dogs. Even a small amount of leaf or berry material can cause gastrointestinal upset in sensitive dogs or small breeds. The berries are more toxic than the leaves, so berry ingestion should be treated with greater urgency.

Are English ivy berries more dangerous than the leaves?

Yes. English ivy berries contain a higher concentration of saponins than the leaves. Berry ingestion is more likely to cause severe symptoms. The berries are small, dark, and can be attractive to curious dogs, especially when they fall to the ground in autumn and winter.

What should I replace English ivy with if I have dogs?

For ground cover, consider creeping thyme, clover, or dwarf mondo grass. For climbing plants, star jasmine (Trachelospermum jasminoides) and climbing hydrangea are generally safer options. For indoor hanging plants, spider plants, Boston ferns, and Swedish ivy are non-toxic alternatives. Always double-check any plant’s safety profile before purchasing.
