Are dogs allowed to eat cherries? All you need to know

Cherries are a popular summer fruit: sweet, juicy and rich in antioxidants. Many dog owners wonder whether they can let their dog enjoy a few too. The short answer is no. Or at least, not without real caution.

Although the flesh of a cherry is not toxic in itself, there are significant risks associated with the stone, stalk and leaves. Below, you can read why caution is advised and what safe alternatives are available.

Why cherries are unsuitable for dogs

The stones, stalks and leaves of cherries contain cyanide, a substance that can be converted into hydrocyanic acid in the body. For humans, a small amount is usually harmless, but for dogs this can quickly become dangerous.

Cyanide blocks the uptake of oxygen in the cells, preventing organs from functioning properly.[1] Smaller dogs are particularly at increased risk.

Symptoms of cherry poisoning in dogs

If a dog ingests too many stones or stalks, the following symptoms may occur:[1][2]

• Difficulty breathing
• Confusion or lethargy
• Dilated pupils
• Red gums
• Vomiting or diarrhoea
• Increased heart rate
• In severe cases: loss of consciousness or death

If you notice any of these symptoms after your dog has eaten cherries or pits, contact your veterinarian immediately.

Is the flesh of the cherry safe?

The flesh of the cherry, without the stone, stalk or skin, is not toxic and even contains some healthy nutrients such as vitamins A and C and antioxidants.[3] Even so, it is not advisable to routinely feed cherries to dogs because:

• there is a high risk of a stone being left behind;
• cherries contain quite a lot of natural sugars;
• the flesh can cause stomach upset in sensitive dogs.

A small piece of pitted, fresh cherry will do no harm. Feeding them regularly, or giving tinned or syrup-based cherries, is not recommended.

Why cherry stones are particularly dangerous

As well as cyanide, the stones also contain hard fibre that can cause blockages or damage to the digestive tract. A whole pit that a dog swallows without chewing carries less cyanide risk, but the moment it gets cracked, that changes.[3] In small dogs, even a single stone can become lodged in the intestines, leading to vomiting, abdominal pain or constipation. In severe cases, surgery may be required to remove it.

Safer fruit alternatives for dogs

Fortunately, there are plenty of fruits that are safe and healthy for dogs. Good alternatives include:

• Apple (without core or seeds): rich in fibre and vitamin C.
• Blueberries: contain antioxidants that support the immune system.
• Watermelon (without seeds and rind): hydrating and low in calories.
• Banana: rich in potassium and natural energy.
• Strawberry: sweet, easily digestible and rich in vitamin C.

Always give fruit in moderation, as a supplement to balanced nutrition.

How much fruit can a dog eat?

Fruit contains natural sugars, and although these are healthier than added sugars, they should only make up a small part of the diet. A general guideline is that fruit should not account for more than 10% of daily calorie intake.

So use fruit as a treat or snack, not as a substitute for the main meal.

What to do if your dog has accidentally eaten cherries

Has your dog swallowed a few cherries or even pits? Keep a close eye on him. Watch for signs such as vomiting, lethargy or breathing difficulties.

If in doubt, or if you don't know how many he has eaten, call the veterinarian immediately. Quick action can prevent serious complications.

Conclusion: can dogs eat cherries?

Cherries may seem harmless, but they carry a real risk for dogs. The flesh itself is not toxic. The stones, stalks and leaves are the problem, thanks to the cyanide they contain and the choking hazard of the pit. It's better to skip cherries altogether and reach for safer fruits such as apple, banana or blueberries.
