Can Dogs Eat Lemons?

When it comes to dogs and fruit, you might be wondering whether lemons are safe for your pup. As a pet owner, it’s important to consider the safety of anything you feed your dog—and lemons are no exception. So, the short answer is no, but let’s break down some of the details about dogs and lemons.

The short answer is no.

The short answer is no. Lemons are toxic to both cats and dogs. They’re also toxic to humans, but if you’ve made it this far into the article, chances are you already know that.

Lemons contain organic compounds called psoralens that can cause severe gastrointestinal upset in all animals that ingest them—and even in humans who eat them!

If your dog gets into a lemon, seek veterinary care immediately. In some cases, there may be no symptoms at all; however, other times the symptoms can be extremely severe and require immediate medical attention (such as vomiting or diarrhea). Depending on how much lemon your pup consumed and how long ago he ate it, there’s also a possibility of kidney failure developing later on down the road if not treated right away with IV fluids.*

Lemons and any citrus fruit are toxic to dogs.

Lemons, and any citrus fruit, are toxic to dogs. Citrus fruits can cause kidney failure in dogs when ingested in large quantities over a short period of time, or if consumed regularly over an extended period of time.

Citrus fruits can also cause stomach upset and diarrhea if eaten by your dog. Vomiting may also be experienced as symptoms after ingesting citrus fruit.

If a dog eats a small amount of lemon, it will likely be fine.

If a dog eats a small amount of lemon, it will likely be fine. However, if the dog eats too much or too many lemons in one sitting, they can experience an upset stomach and other digestive issues. Lemons are acidic and can cause an upset stomach, abdominal pain, vomiting, diarrhea and dehydration in dogs. If you notice any of these symptoms after your dog has eaten lemons, contact your veterinarian immediately.

A large amount of lemon juice could also cause kidney damage to dogs who are not used to consuming it regularly (such as when you offer your pet some citrus fruit).


In summary, lemons and any citrus fruit are toxic to dogs. If your dog has eaten some lemon, you can watch for symptoms of poisoning and contact a veterinarian if necessary. It’s better to avoid giving your pet lemons so that you don’t have to worry about what the effects may be.
