Does Vitamin C Make Limes Good for Dogs?
The main nutrient found in limes is ascorbic acid (vitamin C). It’s a water-soluble vitamin that is essential for the body’s overall health. Here are a few things it does:
- protects your cells against free radicals;
- promotes tissue growth and repair;
- improves skin condition via promoting collagen synthesis;
- supports the immune system.
Limes also contain other nutrients such as potassium, magnesium, and copper. These nutrients can help boost overall health and well-being. It’s also known that citrus fruits can help the liver heal from damage.
From this, it can be concluded that these fruit are high in nutritional value and provide many health benefits for people. But it’s not news that certain human food may turn out toxic or even fatal for pets. So, can dogs eat limes?
Fact 🔍
Dogs don’t need ascorbic acid in their food. Their bodies produce this vitamin for themselves, so supplementing it likely won’t do anything for your furry friend. The risks of the essential oils and acid, on the other hand, aren’t something to overlook!

Citric Acid and Other Compounds That Are Bad for Dogs
Fruits like limes and lemons contain citric acid. It’s a weak organic acid that is used as a food preservative and can also be found in products like toothpaste and mouthwash.
When ingested, citric acid can cause oral irritation, nausea, and vomiting in dogs. The amount of citric acid in limes and lemons is about 5%. It may not seem like a lot, but even this amount is too much for dogs to eat. The limonene present in citrus essential oils can make a dog sick, too, if eaten in large quantities.
Additionally, the peels contain psoralen, produced by the plants to protect them from insects. This is a potentially hepatotoxic substance (leading to liver failure). So if your dog eats the fruit directly from a lime tree, they may suffer more adverse effects than if they lick up a little juice.

Lime Poisoning in Dogs – Symptoms
Can dogs eat limes? It turns out that limes are toxic to dogs. Although they’re rich in vitamins and nutrients, citric acid is harmful to dogs. The acid and essential oils in limes can cause canines to have:
- oral inflammation;
- sensitivity to light;
- low blood pressure;
- lethargy;
- stomach upset;
- vomiting;
- diarrhea.
In severe cases, the acid can also cause liver and kidney damage, erode the tooth enamel and cause other dental problems. Lime poisoning in dogs can occur from eating just a slice of the fruit. Symptoms can develop within 30 minutes to 12 hours after ingestion. If you think your dog has eaten a citrus and shows any worrying symptoms, you should contact a veterinarian immediately.
Dogs Will Not Enjoy The Taste of Lemons and Limes

The sour taste of citrus is not favored by canines. It’s usually off-putting to them, so even if you happen to leave your dogs alone with limes, it’s unlikely that they’ll eat them. If your dog has a particularly big appetite, you should keep the limes away.
Conclusion: Can Dogs Eat Limes?
Ultimately, can dogs eat limes? No, they can’t. Consumption of any part of the lime plant – peels, leaves, or fruit – is bad for dogs. While the fruit does contain some beneficial nutrients, the citric acid, psoralen, and limonene can cause stomach upset and other health problems in canines. Large amounts can be poisonous to dogs and even cause liver damage.
Don’t feed your dog anything with lime in it. Instead, give them a healthy snack that can be safely consumed. Although citrus fruits like lime or lemon are safe for humans, they can be toxic to dogs. Generally, dogs don’t like lemons or limes, so there’s no need to include them in their diet.
