Can Dogs Eat Lemons? A Vet-Backed Answer

Can dogs eat lemons? These tangy, sunny fruits lend bright flavor to an array of our own refreshing treats and drinks, so it’s only natural that many pet parents wonder whether they can share lemons or lemonade with their dogs.

There are no real health benefits to be gained by feeding your dog a lemon. In fact, consuming too much lemon—or even just a little bit—could harm your pup. Read on to discover why lemons aren’t a wise choice for sharing.

Why lemons are bad for dogs

Although they may not be as dangerous for dogs as onions or grapes, lemons are not appropriate treats. The rind is a choking hazard, and consuming a too-large piece can cause a life-threatening bowel obstruction. The bitter taste of lemons isn’t merely unpleasant to dogs—the citric acid and essential oils found in lemons can cause discomfort. Lemons also contain compounds called psoralens, which are not only toxic to dogs in large quantities but can also irritate the skin or gums and GI tract. Psoralens can be found throughout the fruit, but the highest concentrations are in the skin, seeds and pith. For all these reasons, the answer to the question, “Can my dog eat lemons?” is a decisive no.

What to do if your dog eats lemons

Luckily, your dog may be averse to lemons’ sour, bitter flavor and might naturally choose to stay away from them. However, as many pet parents know, some dogs are only too happy to gobble up anything that seems edible, even (or especially) when it ends up in front of them by accident.

If your dog only has a little lick of lemon when you’re distracted, there is typically no reason to be alarmed. However, the more lemon that’s ingested, the higher the risk of a negative reaction in your dog. Symptoms of illness to watch out for include:

• Vomiting
• Diarrhea
• Depression
• Dermatitis

If your dog displays any of these symptoms after eating lemons, contact your veterinarian immediately or call the ASPCA Animal Poison Control Center at 888-426-4435. Note: You may be charged a consultation fee.

Since lemon seeds, rinds and piths present the most potential for problems, is a drink of lemonade OK? Can dogs have lemon juice? Again, there are significant negatives and no health benefits to be gained by offering these to your dog, so the answer to each of these questions is also a resounding no. Lemonade usually contains a lot of sugar, which can be very unhealthy for canines.

How can I prevent my dog from eating lemons?

If you have a curious pup who loves to chow down on anything that vaguely resembles food, keep lemons securely out of reach on a high shelf or in your refrigerator.

Frequently Asked Questions

Can dogs eat lemons? No. Lemons contain citric acid, essential oils and compounds called psoralens that can irritate a dog's gastrointestinal tract, skin and gums. The rind also poses a choking hazard and can cause a bowel obstruction if swallowed in a large piece. There are no meaningful nutritional benefits for dogs that would outweigh these risks. https://www.aspca.org/pet-care/animal-poison-control

What should I do if my dog ate a lemon? A brief lick of lemon juice is unlikely to cause serious harm, but watch your dog closely for vomiting, diarrhea, lethargy or signs of skin irritation (dermatitis). If your dog consumed a larger amount — or ate the rind, seeds or pith — contact your veterinarian right away or call the ASPCA Animal Poison Control Center at 888-426-4435 (a consultation fee may apply). https://www.aspca.org/pet-care/animal-poison-control

Are lemon seeds toxic to dogs? Lemon seeds, along with the pith and rind, contain the highest concentrations of psoralens — compounds that are toxic to dogs in significant quantities and can irritate the GI tract and mucous membranes. Seeds also present a choking risk. If your dog swallowed several seeds, consult your veterinarian even if no symptoms appear immediately. https://www.aspca.org/pet-care/animal-poison-control

Can dogs drink lemonade or lemon juice? No. Lemonade typically contains high amounts of added sugar, which can contribute to weight gain and digestive upset in dogs, and it still delivers the citric acid and essential oils found in fresh lemons. Plain lemon juice is equally problematic. Neither offers any nutritional value for dogs, and both should be kept out of reach. https://sites.tufts.edu/petfoodology/ https://www.aspca.org/pet-care/animal-poison-control

Are there safe citrus or fruit alternatives for dogs? Some fruits are far better choices for an occasional treat. Small amounts of watermelon (seedless, no rind), blueberries and sliced apple (no seeds or core) are generally well tolerated by dogs and provide vitamins and fiber. Always introduce any new food gradually and keep treats to no more than 10% of your dog's daily caloric intake. When in doubt about a specific fruit, check with your veterinarian before sharing. https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals

How do I keep my dog away from lemons at home? Store lemons on a high shelf, inside a closed cabinet or in the refrigerator — anywhere your dog cannot nose around or counter-surf. If you have a lemon tree in your yard, fence off the area or supervise outdoor time closely, since fallen fruit and leaves can be just as problematic as the fruit itself. Consistent management is the simplest way to prevent an accidental ingestion.
