What fruits and vegetables are toxic to dogs?


As dog owners, we want to provide our furry friends with a healthy and balanced diet. While fruits and vegetables are generally beneficial for dogs, it’s important to be aware of the ones that can be toxic to them. In this article, we will discuss some fruits and vegetables that can be harmful to dogs and explain why they should be avoided.



Onions contain a compound called disulfide, which can cause weakness in dogs’ limbs, acute hemolytic anemia (a condition where red blood cells are destroyed), and even organ failure in severe cases. It’s crucial to keep onions and any food containing them away from dogs to prevent serious health issues or even fatalities.


Dogs should not consume raw potatoes or sprouted potatoes. Raw potatoes contain a toxin called solanine, which can lead to diarrhea, abdominal pain, and difficulty breathing if ingested. Only cooked potatoes have reduced levels of solanine, making them safe for dogs to eat in small amounts.


Tomatoes contain alkaloids that, when consumed in excess, can cause drooling, drowsiness, and breathing difficulties in dogs. While small amounts of tomatoes are generally harmless, it’s best to avoid feeding dogs large quantities.


Celery is rich in fiber, which can be difficult for dogs to digest. Consumption of celery can lead to constipation and digestive problems in dogs. It’s advisable to avoid feeding celery to dogs or provide it in very small, well-chopped pieces if necessary.


Leeks contain a compound called thiosulfate, which can damage the components of a dog’s blood, leading to anemia. They are highly toxic to dogs and should never be included in their diet.

Allium Vegetables (Onions, Ginger, Garlic, etc.)

Vegetables belonging to the allium family, such as onions, ginger, and garlic, can cause significant damage to a dog’s kidneys if ingested. These vegetables can trigger excessive urination, potentially leading to kidney problems. It’s essential to keep them away from dogs to ensure their well-being.



Grapes contain a high level of glucose, which dogs are particularly sensitive to. Ingesting grapes can lead to vomiting and diarrhea, causing toxicity in dogs. It’s crucial to avoid feeding grapes or raisins to dogs, as they can have severe consequences on their health.


Pineapple is a highly allergenic fruit for dogs, and its consumption can cause allergies, diarrhea, and dehydration. It’s best to refrain from giving pineapple to dogs to prevent any adverse reactions.


Persimmons have high sugar content, and excessive consumption can burden a dog’s digestive system, leading to constipation and intestinal inflammation. It’s important to moderate the intake of persimmons or avoid them altogether.


Sugarcane is not easily digestible for dogs and can cause gastrointestinal discomfort. Since it provides no nutritional benefit to dogs, it’s recommended to keep them away from sugarcane.


Cherry pits and leaves contain cyanide, which is toxic to dogs. Even the flesh of cherries should be given with caution, as excessive consumption can cause breathing difficulties and shock in dogs. It’s advisable to avoid cherries altogether to ensure the safety of your furry companion.

Pineapple and Lemon

Both pineapple and lemon can irritate a dog’s intestines, leading to symptoms such as vomiting and diarrhea. These fruits should be avoided to prevent any discomfort for dogs.


While fruits and vegetables are generally healthy for dogs, it’s important to be aware of the potential risks associated with certain varieties. Onions, grapes, cherries, and various other fruits and vegetables can be toxic or cause adverse reactions in dogs. As responsible dog owners, it’s our duty to ensure our furry friends are safe and healthy by providing them with a balanced and suitable diet. If in doubt about the safety of any specific food, it’s always best to consult with a veterinarian.
