Can Dogs Eat Licorice? The short answer is no—dogs should not eat licorice candy. While this might disappoint your furry friend, understanding why licorice is dangerous for dogs could save you an emergency vet visit. In this comprehensive guide, you’ll learn about the specific compounds that make licorice toxic to dogs, the difference between candy and medicinal licorice root, symptoms of licorice poisoning, and safe treat alternatives your dog will love.
Whether you’re a first-time pet owner or a seasoned dog parent, this article will give you the knowledge you need to keep your companion safe while still treating them to delicious, dog-appropriate snacks.
What Is Licorice and Why Is It Popular?
Licorice comes from the root of the Glycyrrhiza glabra plant, a legume native to Europe and Asia. For thousands of years, humans have used licorice root for both its distinctive sweet flavor and medicinal properties. The root contains glycosides, saponins, flavonoids, and most importantly, glycyrrhizin—a compound that’s 30 to 50 times sweeter than regular sugar.
In the confectionery world, licorice appears in two main forms: black licorice and red licorice. Black licorice typically contains actual licorice root extract or anise flavoring, while red licorice (like Twizzlers) usually contains no real licorice at all, relying instead on artificial flavoring and high amounts of sugar.
The medicinal form of licorice root has been used in traditional medicine to treat digestive issues, respiratory problems, and inflammation. This creates confusion for pet owners—if licorice root has health benefits for humans, shouldn’t it be safe for dogs too?
The reality is more nuanced than that simple assumption.
The Dangers of Licorice for Dogs: Understanding Glycyrrhizin Toxicity
What Makes Licorice Toxic to Dogs?
The primary danger in licorice comes from glycyrrhizin, the active compound in licorice root. This substance has a chemical structure similar to naturally occurring corticosteroids, which affects how a dog’s body regulates sodium, potassium, and fluid balance.
When dogs consume glycyrrhizin, it can result in high blood pressure MasterClass, creating a cascade of potentially serious health problems. The compound interferes with the adrenal glands’ normal function, causing the body to retain sodium while losing potassium—a dangerous electrolyte imbalance.
How Glycyrrhizin Affects Your Dog’s Body
When a dog ingests licorice containing glycyrrhizin, several physiological changes occur. The compound causes water retention and increased urine production, leading to more frequent urination and excessive thirst. Blood pressure rises, which can manifest as restlessness, panting, and rapid heart rate.
A 2024 study published in the Journal of Animal Physiology and Animal Nutrition examined glycyrrhizin intake in dogs Wiley Online LibraryPubMed, finding that while therapeutic doses under veterinary supervision showed no detectable harmful effects, uncontrolled consumption remains risky. The key difference is controlled, measured dosing versus accidental candy consumption.
Most critically, potassium depletion can cause muscle weakness, tremors, and in severe cases, muscle paralysis. The cardiovascular system becomes stressed, potentially leading to irregular heart rhythms in serious cases of toxicity.
Can Dogs Eat Black Licorice? The Most Dangerous Variety
Black licorice poses the greatest risk to dogs because it contains the highest concentration of glycyrrhizin. Traditional black licorice candy combines licorice root extract with sugar, molasses, and sometimes anise oil, creating a perfect storm of ingredients that can harm your pet.
Even a small amount of black licorice can be problematic, especially for smaller dogs. A Chihuahua eating one piece of black licorice faces considerably more risk than a Great Dane eating the same amount, simply due to the concentration of glycyrrhizin relative to body weight.
Beyond glycyrrhizin, black licorice’s high sugar content creates additional concerns. Dogs don’t process sugar the same way humans do, and excessive sugar intake can lead to obesity, dental problems, gastrointestinal upset, and potentially diabetes with long-term exposure.
The Xylitol Danger in Sugar-Free Licorice
Sugar-free licorice varieties present an even more immediate threat. Many sugar-free candies contain xylitol, an artificial sweetener that is extremely toxic to dogs. Xylitol can potentially lead to liver failure, severe hypoglycemia, and even death if ingested Great Pet Care.
Within 30 minutes of consuming xylitol, a dog can experience a dangerous drop in blood sugar, leading to weakness, seizures, and loss of consciousness. This is a veterinary emergency requiring immediate professional intervention.
Can Dogs Eat Red Licorice? Not Much Better
Red licorice (often sold as Twizzlers or similar brands) typically doesn’t contain actual licorice root, which might seem safer. However, red licorice comes with its own set of problems for dogs.
These candies are loaded with sugar, wheat flour, corn syrup, and artificial colors and flavors. While they may lack glycyrrhizin, the high sugar content can still cause digestive upset, including vomiting, diarrhea, and bloating. Dogs with gluten sensitivities may experience additional reactions to the wheat flour.
Some dogs may also have allergic reactions to artificial colors and preservatives commonly found in red licorice. Symptoms can include itching, skin irritation, and gastrointestinal distress.
The bottom line? Both black and red licorice candy should be kept away from your dog.
Licorice Root for Dogs: When Can It Be Beneficial?
Here’s where the story becomes more interesting. While licorice candy is dangerous for dogs, medicinal licorice root—used properly and under veterinary guidance—can actually provide health benefits.
The Medicinal Properties of Licorice Root
Licorice root contains powerful anti-inflammatory properties that can help dogs with various conditions. Unlike synthetic corticosteroids, licorice enhances the body’s natural anti-inflammatory processes without seriously compromising the immune system.
Veterinarians and holistic practitioners sometimes recommend licorice root for:
Digestive Issues: Licorice root can soothe stomach ulcers, acid reflux, and indigestion by stimulating mucus production that protects the gut lining. This protective barrier helps prevent a leaky gut, where undigested food particles enter the bloodstream and create inflammation.
Joint Pain and Arthritis: The anti-inflammatory compounds in licorice root can provide relief from joint pain and arthritic conditions, potentially allowing dogs to reduce their dependence on stronger medications.
Skin Conditions: Topical application of licorice tea, oil, or salve can ease the itching and burning from flea allergies, contact dermatitis, and other skin irritations.
Respiratory Problems: Licorice acts as an expectorant, helping dogs expel excess mucus that blocks their airways while soothing sore throats.
Immune System Support: Licorice root can boost the reticuloendothelial system, which manages specialized cells that find and destroy dead blood cells and invasive microbes.
What Is DGL (Deglycyrrhizinated Licorice)?
DGL, or deglycyrrhizinated licorice, may be able to provide the soothing benefits of licorice without the side effects westiefoundation. The glycyrrhizin has been removed from DGL, eliminating the potential for dangerous side effects while retaining the beneficial properties.
DGL generally makes licorice safer for dogs and people who may have health issues that make plain licorice root problematic. However, even DGL supplements should only be given to dogs after consulting with a veterinarian.
How Much Licorice Is Toxic to Dogs?
The exact amount of licorice that becomes toxic varies depending on several factors: your dog’s size, age, overall health, and the specific concentration of glycyrrhizin in the product.
Smaller dogs face greater risk even from minimal amounts due to their lower body weight. A single piece of black licorice might not immediately harm a large breed dog, but could cause noticeable symptoms in a toy breed.
The type of licorice matters significantly. Black licorice contains substantially more glycyrrhizin than red varieties, making it more dangerous in smaller quantities.
Individual sensitivity also plays a role—some dogs may be more sensitive to glycyrrhizin’s effects than others, just as some people have more pronounced reactions to certain substances.
As a general safety rule, no amount of licorice candy should be considered safe for dogs. The combination of glycyrrhizin, sugar, and potential xylitol makes the risk simply not worth taking.
Symptoms of Licorice Poisoning in Dogs
If your dog has consumed licorice, watch carefully for these symptoms of toxicity:
Early Warning Signs:
- Increased thirst and urination
- Restlessness and panting
- Vomiting and diarrhea
- Lethargy and weakness

When Licorice Root Might Be Appropriate: Veterinary-Supervised Use
While candy is off-limits, there are specific circumstances where a veterinarian might recommend licorice root supplements for your dog.
Proper Dosing for Medicinal Licorice
If your holistic veterinarian recommends licorice root, proper dosing is essential. General guidelines include:
Tincture Form: 12 to 20 drops per 20 pounds of body weight, twice daily
Tea Form: 30 to 60 drops per 20 pounds of body weight, twice daily (steep 1 teaspoon licorice root in 1 cup of water)
These are starting points only—your veterinarian will provide specific instructions based on your dog’s individual needs.
Important Precautions and Contraindications
Licorice root should not be used in diabetic animals, pregnant or nursing animals westiefoundation. Dogs with heart disease, liver disease, kidney disorders, or high blood pressure should not receive licorice root supplementation.
Even in healthy dogs, licorice should only be used for two weeks at a time without veterinary supervision. For longer use, dandelion leaf should be given alongside licorice to act as a diuretic and provide dietary potassium, helping to prevent the electrolyte imbalances that prolonged use can cause.
Making Licorice Oil for Topical Use
If your veterinarian recommends topical licorice for skin issues, you can make your own infusion:
- Place chopped dried licorice root in a glass jar
- Cover completely with olive oil, adding an extra half-inch on top
- Seal tightly and place in a warm cupboard away from sunlight
- Let sit for 30 days
- Strain through cheesecloth and store in the refrigerator
The resulting oil can be applied to irritated skin, though most dogs will lick it off due to its sweet taste. This is generally safe, but use sparingly to prevent ingestion of large amounts.
Black Licorice vs. Red Licorice vs. Licorice Root: A Comparison
Understanding the differences between licorice varieties helps clarify why blanket warnings exist:
Black Licorice Candy:
- Contains glycyrrhizin (highest concentration)
- High in sugar
- May contain xylitol in sugar-free versions
- Most dangerous for dogs
- No redeeming nutritional value
Red Licorice Candy:
- Usually contains no actual licorice
- High in sugar and artificial ingredients
- May contain xylitol
- Can cause digestive upset
- No nutritional benefits
Medicinal Licorice Root:
- Contains glycyrrhizin but in controlled amounts
- Provides anti-inflammatory benefits when properly dosed
- Must be administered under veterinary supervision
- Available as tinctures, teas, or in DGL form
- Can support digestive, skin, joint, and respiratory health
The key takeaway: candy is always dangerous, while medicinal preparations might be beneficial under professional guidance.
The Bottom Line: Keep Licorice Away from Your Dog
While licorice might be a beloved treat for humans, it poses unnecessary risks to our canine companions. The glycyrrhizin in black licorice can cause electrolyte imbalances, high blood pressure, and potentially life-threatening complications. Red licorice, though typically free from glycyrrhizin, still contains harmful amounts of sugar and artificial ingredients.
The exception to this rule is medicinal licorice root used under veterinary supervision, particularly DGL formulations. When properly dosed and monitored, licorice root can provide anti-inflammatory benefits for dogs with certain health conditions.
The safest approach? Keep all licorice candy securely stored away from your dog, choose dog-appropriate treats instead, and consult your veterinarian before giving any herbal supplements. Your dog’s wagging tail when you offer them a healthy alternative treat will be just as enthusiastic—and you’ll have peace of mind knowing you’re keeping them safe.
