Is Ground Ivy Poisonous to Dogs? | Creeping Charlie Facts

You catch your dog snacking on a low-growing vine in the yard and your mind jumps to poisoning. The plant might be ground ivy—also called creeping Charlie—and the answer is more layered than a simple yes or no.

The ASPCA lists a plant called creeping Charlie (Pilea nummulariifolia) as non-toxic to dogs, cats, and horses. But true ground ivy (Glechoma hederacea) is a different species, and while it’s not classified as a major toxin, eating a lot of it can still upset your dog’s stomach.

If you suspect an emergency: Call 911 (or your local emergency number) immediately. In the U.S., you can also call Poison Control at 1-800-222-1222. Do not wait to see if symptoms improve.

What Is Ground Ivy

Ground ivy is a perennial evergreen creeper in the mint family (Lamiaceae). It has round, scalloped leaves and produces small purple-blue flowers in spring. The plant spreads quickly across lawns and shaded areas, which is why you’ll often find it mixed in with grass.

Because it belongs to the mint family, the leaves release a faint, pleasant smell when crushed. That aroma is one clue that helps distinguish it from look-alike plants that could be dangerous.

Despite its reputation as a weed, ground ivy has a long history of use in folk medicine—but that doesn’t mean it’s safe for dogs in large quantities. The key is moderation and knowing the difference between this plant and truly toxic varieties.

Why The Confusion Sticks

Most of the worry about ground ivy comes from name overlap and mixed information online. Here’s what fuels the confusion:

• Shared names, different plants: Both Glechoma hederacea and Pilea nummulariifolia are called creeping Charlie, but only the first is true ground ivy. The ASPCA’s non-toxic listing applies to the Pilea species.
• English ivy is toxic: English ivy (Hedera helix) is a completely different plant that causes vomiting, diarrhea, and skin irritation in dogs—and it’s often confused with ground ivy.
• Livestock warnings: The USDA warns against letting livestock graze in areas heavily infested with ground ivy, especially when other forage is scarce. That advice is for large animals eating large amounts, not a dog nibbling a few leaves.
• Conflicting online sources: Some pet websites call ground ivy mildly toxic, while others say it’s safe. Most of those warnings are based on the toxic English ivy or on very heavy consumption.
• Natural remedy reputation: Ground ivy has been used in herbal medicine for centuries, which can make people assume it’s either very helpful or very dangerous—neither extreme is accurate for dogs.

When people ask about ground ivy being poisonous to dogs, the answer comes down to which plant you’re actually dealing with and how much your dog ate.

What Happens If A Dog Eats Ground Ivy

If your dog snacks on a few leaves of true ground ivy, the most likely outcome is nothing at all. Some dogs, especially those with sensitive stomachs, may experience mild vomiting or a single bout of loose stool. These symptoms are usually self-limiting and don’t require a vet visit.

The bigger risk comes from large quantities—if your dog eats a whole patch of ground ivy, the sheer volume of plant material can cause gastrointestinal upset. The UC Davis Veterinary School’s English ivy toxicity page clarifies that English ivy is the truly dangerous species, not ground ivy. For proper identification, the USDA Natural Resources Conservation Service provides a detailed ground ivy identification sheet with photos and distinguishing features.

If your dog eats ground ivy and shows only one or two mild symptoms, monitoring at home is usually sufficient. But if symptoms persist or worsen, call your vet.

How To Tell Ground Ivy From English Ivy

Mistaking English ivy for ground ivy is the most common cause of unnecessary panic. Here’s how to tell them apart:

1. Check the leaves: Ground ivy has round, kidney-shaped leaves with scalloped edges. English ivy has pointed, lobed leaves that look like a star or maple leaf.
2. Look at the vines: Ground ivy creeps along the ground and roots at nodes. English ivy climbs walls, trees, and fences using aerial rootlets.
3. Smell the leaf: Crush a leaf. Ground ivy smells minty or slightly medicinal. English ivy has no noticeable odor.
4. Consider the location: Ground ivy thrives in lawns, shady gardens, and disturbed soil. English ivy is usually found climbing structures or growing as a ground cover along wooded edges.
5. Use an identification app or guide: When in doubt, take a clear photo and compare with the USDA’s identification sheet or ask your local extension office.

Getting the identification right is the most important step. If you confirm it’s ground ivy, the risk is low. If it’s English ivy, contact your veterinarian promptly.

When Should You Call The Vet

Most dogs that eat ground ivy won’t need medical attention. But there are situations where a call to your veterinarian is wise.

Puppies, senior dogs, and those with existing health conditions are more vulnerable to dehydration from any kind of GI upset. The UC Davis toxic plant list is a reliable resource for checking whether a plant is genuinely dangerous—English ivy is on that list, ground ivy is not.

The Bottom Line

Ground ivy is not a major poison risk for dogs. Occasional nibbles usually cause no problems, and heavy ingestion may lead to mild vomiting or loose stool that resolves on its own. The real danger is confusing this plant with English ivy, which is toxic and requires a vet visit.

If you’re unsure which plant your dog ate, take a sample to your veterinarian. They can identify it and give you advice tailored to your dog’s size, age, and health history. When in doubt, a quick call to your vet or the ASPCA Animal Poison Control Center (888-426-4435) can save you hours of worry.
