Is Creeping Thyme Safe For Dogs? A Comprehensive Guide

As dog owners, we always strive to provide the best care and ensure the safety of our furry companions. Regarding gardening and landscaping, it’s crucial to be aware of the plants in our outdoor spaces, as some plants can be harmful or even toxic to dogs. Creeping thyme, a famous ground cover with aromatic leaves, has caught the attention of many garden enthusiasts. However, before incorporating it into your landscaping, it’s essential to ask: Is creeping thyme safe for dogs? In this comprehensive guide, we’ll explore the potential risks and benefits of having creeping thyme around your canine friends.

Is creeping thyme safe for dogs?

Yes, creeping thyme is generally safe for dogs, but there are some considerations to consider. Creeping thyme contains aromatic compounds like thymol and carvacrol, which can have physiological effects on dogs if ingested in large quantities. While small amounts of thyme are unlikely to cause harm, consuming significant amounts could lead to digestive upset, vomiting, or diarrhea. It’s a good idea to monitor your dog’s interactions with creeping thyme and prevent them from consuming excessive amounts. If you’re concerned, you might opt for dog-safe ground cover alternatives in your garden. As always, consulting your veterinarian is recommended if you notice any unusual symptoms or behaviors in your dog after exposure to creeping thyme.

Understanding Creeping Thyme

Creeping thyme, scientifically known as Thymus serpyllum, is a versatile and aromatic herb that belongs to the Lamiaceae family, which also includes mint, basil, and rosemary. This low-growing perennial herb is native to Europe but has found its way into gardens and landscapes worldwide due to its numerous benefits and aesthetic appeal.

Creeping thyme is characterized by its dense, mat-like growth, making it an excellent choice for ground cover in gardens and between paving stones. It typically reaches a height of around 2 to 3 inches and spreads vigorously, forming a lush carpet of foliage. The leaves are small, oval-shaped, and densely packed along the stems. Depending on the variety, creeping thyme can produce flowers in shades of pink, purple, white, or even red, adding extra visual interest to its surroundings.

One of the standout features of creeping thyme is its delightful aroma. The leaves of this herb are rich in essential oils, which give rise to its distinct scent. The primary aromatic compounds found in creeping thyme are thymol and carvacrol, both of which contribute to its characteristic fragrance. These compounds are not only responsible for the herb’s pleasant aroma but also for some of its potential physiological effects.

Creeping thyme is widely used in culinary practices due to its aromatic flavor. It adds a unique earthy and slightly peppery taste to dishes, making it a popular choice for seasoning meats, vegetables, and soups. Additionally, thyme has been traditionally recognized for its potential medicinal properties. Its essential oils, particularly thymol, possess antimicrobial and antiseptic qualities, which have led to its use in natural remedies for coughs, colds, and sore throats.

In the realm of gardening and landscaping, creeping thyme offers numerous benefits. Its vigorous spreading nature makes it an adequate ground cover that helps prevent soil erosion and suppress weed growth. This low-maintenance herb requires minimal care, making it an ideal choice for novice and experienced gardeners. Furthermore, the colorful flowers adorn creeping thyme plants attract pollinators like bees and butterflies, contributing to a vibrant and biodiverse garden ecosystem.

Regarding pets, particularly dogs, it’s essential to consider whether creeping thyme poses any risks. While the herb is generally safe for dogs in small amounts, its higher concentrations of aromatic compounds could lead to digestive issues if ingested in excessive quantities. Monitoring your dog’s interactions with creeping thyme and preventing them from consuming large amounts is advisable to avoid potential complications.

Aromatic Compounds And Their Effects

Aromatic compounds are organic molecules known for their distinctive and often pleasant fragrances. They are responsible for the captivating scents in various plants, flowers, herbs, and essential oils. In creeping thyme (Thymus serpyllum), aromatic compounds play a significant role in shaping its aroma, flavor, and potential effects. Two essential aromatic compounds found in creeping thyme are thymol and carvacrol.

Thymol: Thymol is a natural monoterpene phenol commonly present in various herbs, including thyme, oregano, and basil. It is responsible for the firm, aromatic scent of these plants and is often used in producing essential oils for its antimicrobial properties. Thymol has been studied for its potential health benefits, including its role as an antiseptic, antibacterial, and antifungal agent. It is also used in some dental products for its ability to combat bacteria that contribute to oral health issues.

Carvacrol: Carvacrol is another monoterpene phenol contributing to the distinct aroma of creeping thyme. It is found in various herbs and spices, including oregano and savory. Like thymol, carvacrol possesses antimicrobial properties and has been investigated for its potential therapeutic applications. Research suggests that carvacrol may have antioxidant, anti-inflammatory, and antimicrobial effects, making it a compound of interest in natural medicine and food preservation.

Effects on Dogs: While thymol and carvacrol offer potential benefits to humans and have been used in various products, their effects on dogs can differ. Dogs have a keen sense of smell, and certain aromatic compounds can have physiological effects. In the case of creeping thyme, the presence of thymol and carvacrol in the plant’s leaves contributes to its alluring scent.

Safety Measures: To ensure the safety of your canine companion, it’s wise to be mindful of their interactions with creeping thyme and other plants containing aromatic compounds. If you have creeping thyme in your garden, consider limiting your dog’s access to the plant to prevent overconsumption. Additionally, be vigilant while your dog is outdoors to prevent them from ingesting large quantities of the herb.

Potential Risks For Dogs

While creeping thyme (Thymus serpyllum) can offer various benefits and contribute to the aesthetics of your garden, it’s essential to be aware of the potential risks it might pose to your canine companions. Here are some potential risks associated with creeping thyme for dogs:

Digestive Upset:

Creeping thyme contains aromatic compounds like thymol and carvacrol, contributing to its fragrance and potential physiological effects. However, these compounds, when consumed in large amounts, can cause digestive upset in dogs. Ingesting excessive thymol and carvacrol could lead to symptoms such as vomiting, diarrhea, and abdominal discomfort.

Sensitivity and Allergies:

Just as humans can be sensitive or allergic to certain plants, dogs can also have adverse reactions. Some dogs might be sensitive to the aromatic compounds found in creeping thyme. Skin irritation, itching, and rashes are possible symptoms of an allergic reaction.

Preexisting Health Conditions:

Dogs with preexisting health conditions, particularly gastrointestinal issues, might be more susceptible to the adverse effects of consuming creeping thyme. The aromatic compounds could exacerbate their condition and lead to more severe discomfort.

Quantity Matters:

The key consideration with creeping thyme is the amount ingested. Small nibbles or incidental consumption are unlikely to cause harm. However, if your dog consumes a significant quantity of creeping thyme leaves or flowers, it increases the likelihood of adverse reactions.

Variability Among Dogs:

It’s important to note that individual dogs can react differently to plants and their compounds. Some dogs might tolerate creeping thyme without issues, while others might be more sensitive. Factors such as size, age, overall health, and the quantity ingested can all influence how a dog responds.


Ultimately, whether creeping thyme is safe for dogs has a nuanced answer. While the plant can offer various benefits, its higher concentrations of aromatic compounds require careful consideration for dog owners. By understanding the potential risks, benefits, and preventive measures, you can make an informed decision about whether to include creeping thyme in your garden while ensuring the safety and well-being of your beloved four-legged friends.


How can I keep my dog from eating creeping thyme?

To prevent your dog from eating creeping thyme, consider designating safe areas in your garden, supervising your dog outdoors, and training them with commands like “leave it” or “drop it.” Providing plenty of toys and distractions can also help redirect their attention away from plants.
What are the benefits of using creeping thyme in landscaping?

Creeping thyme offers benefits such as erosion control, weed suppression, low maintenance, and a charming appearance as ground cover. It also attracts pollinators, adds fragrance to the environment, and can be used in culinary dishes due to its aromatic leaves.

Are there dog-safe alternatives to creeping thyme?

Yes, there are dog-safe alternatives for ground cover in gardens. Consider plants like Irish moss, sedum, Corsican mint, or even grasses labeled as safe for dogs. These alternatives provide similar visual appeal without the potential risks of creeping thyme.
