I work as a mobile dog groomer and pet care educator, and I spend most of my week moving between homes, checking coats, skin conditions, and diet habits that owners casually mention during grooming sessions. One question that comes up more often than you would expect is whether licorice is safe for dogs, especially when people share sweets or herbal treats without thinking twice.
I’ve seen everything from small chewy licorice pieces dropped near a feeding bowl to herbal supplements mixed into food bowls for older dogs. It usually starts as a harmless habit, but it can quickly turn into confusion.
How licorice shows up in real home routines
In my daily rounds, I notice licorice rarely comes from a deliberate pet diet choice but more often from human snacks shared in passing moments. A customer last spring mentioned that their small terrier had been licking black licorice pieces that kept falling from a candy bowl left on a low table. The dog didn’t show immediate distress, which made the owner assume it was fine, but that kind of assumption is exactly where problems begin over time. Dogs react differently. Licorice is tricky.
What I usually explain is that licorice is not a straightforward “safe or unsafe” ingredient for dogs, because it depends on form, amount, and what else is mixed into it. Pure licorice root used in herbal remedies behaves very differently from sugary black or red licorice candy, which often contains additives and sweeteners that further complicate matters. I’ve had cases where dogs seemed fine after a small taste, but repeated exposure created digestive discomfort that owners only noticed later. The slow buildup is what makes it easy to miss at first.
Why I caution owners during grooming visits
During grooming sessions, I often end up talking about diet safety while brushing out coats or checking skin irritation, because those moments feel more relaxed for owners to ask questions. I usually point them toward reliable guidance and mention that if they are unsure about any food item, they should check trusted veterinary resources, such as the ASPCA Pet Poison Control hotline, before assuming it is harmless. These conversations usually come after a dog has already been exposed to something questionable, not before, which is why I try to normalize asking early instead of reacting late. A few minutes of checking can prevent a lot of stress later for both the owner and the dog.
What I’ve learned is that people don’t always connect herbal ingredients like licorice to potential pet risks because they sound natural and therefore safe. I’ve worked with households where licorice tea was part of the daily routine, and dogs occasionally licked spilled drops from cups without anyone realizing the cumulative exposure. Over time, I noticed patterns where mild stomach upset or unusual lethargy was dismissed as unrelated, even though diet changes were happening in the background. That gap between perception and reality is where most feeding mistakes happen.

What makes licorice potentially risky for dogs
The concern with licorice stems from compounds in the root, especially glycyrrhizin, which can affect hormone balance and cause fluid retention at higher doses. In small amounts, a single accidental bite of candy may not show obvious effects, but repeated ingestion or concentrated herbal extracts can create strain on a dog’s system. I’ve seen dogs with sensitive stomachs react more quickly than others, especially when licorice is combined with other sweeteners or oils. One medium-sized spaniel I remember had mild bloating after several days of licking flavored herbal sticks left on a coffee table.
Another issue I point out is that commercial licorice candy is not just licorice. It often includes sugar, artificial flavoring, and sometimes sugar substitutes that are far more dangerous than licorice itself. Xylitol, for example, is a major concern in some sugar-free products, and even small amounts can create serious complications for dogs. I always tell owners that the label matters more than the treat’s name. A product might look harmless at first glance, but still contain ingredients that dogs should never consume.
There is also the herbal supplement side, which I see in homes where owners are trying natural remedies for inflammation or digestion support. Licorice root in concentrated form is sometimes used in human herbal routines, but dogs process it differently, and dosing is rarely straightforward without veterinary guidance. I’ve had clients who thought adding a small herbal drop to food would help skin allergies, only to later realize it was contributing to restlessness or changes in appetite. That uncertainty is why I treat licorice like a “check first” ingredient rather than a casual one.
Safer choices and what I suggest instead
When owners ask me what they can offer instead of sharing sweets like licorice, I usually steer them toward simple, single-ingredient treats that don’t carry hidden additives. Plain cooked pumpkin, small apple slices without seeds, or commercial dog treats with clear labeling are far easier to manage. I’ve seen dogs respond better to consistency in treats rather than occasional human snacks that vary in ingredients and sugar levels. It also makes tracking reactions much easier if something doesn’t sit well.
In my experience, the safest approach is not about eliminating variety but about keeping control over what enters the dog’s diet without confusion. A customer I worked with over several months eventually stopped sharing any human candy after noticing their dog’s digestion stabilized once the habit ended. That change was small but made a noticeable difference in coat condition and energy levels during grooming sessions. Small habits matter more than people expect. Less guessing, fewer problems.
Some owners feel guilty removing shared treats because it feels like cutting off bonding moments, but dogs don’t need sugary or herbal human snacks to feel included. They respond just as strongly to routine, attention, and predictable rewards that don’t introduce dietary uncertainty. I’ve seen calmer dogs simply because their treat routine became consistent, rather than random table scraps or shared sweets. That kind of stability often shows up in better behavior during grooming and vet visits as well.
Licorice sits in that awkward category where it is neither clearly harmless nor universally toxic in tiny accidental amounts, which is exactly why I treat it cautiously in every conversation. When owners slow down and look at ingredients instead of names, they usually make safer choices without needing strict rules. Most of the time, prevention is just awareness during everyday routines, not major dietary overhauls. That shift alone reduces many avoidable issues I see in the field.
