Online, you can easily find articles and guides warning against feeding bell peppers to your dog. Yet some influencers claim their dogs eat the crunchy vegetable daily. So what’s the truth? Is there a significant risk of poisoning, or can dogs actually digest bell peppers? Anke Jobi, a dog nutritionist, explains whether the vegetable is truly dangerous.

Some Bell Peppers Contain High Solanine Levels–Toxic to Dogs

Bell peppers, like tomatoes or potatoes, are part of the nightshade family. They contain the chemical compound solanine, which is mildly toxic to both humans and animals. However, the riper the bell pepper, the less solanine it contains, as the substance breaks down during ripening. 

With bell peppers, the color indicates their ripeness: Red, yellow, and green bell peppers are not different varieties but different stages of ripeness. Unripe peppers with high solanine content are green; yellow and orange peppers are moderately ripe, and red ones are fully ripe.  

Unripe Bell Peppers Can Lead to Poisoning in Dogs

If a dog eats a large amount of unripe—specifically green—bell peppers, it can indeed become poisoned. The severity of symptoms can vary, depending on factors such as how much the dog ate, its size, and its health condition. 

Classic symptoms of solanine poisoning include cardiovascular issues with heart rhythm problems, digestive tract issues like diarrhea and vomiting. Neurological issues such as breathing difficulties, paralysis, and seizures can also occur. The dog’s mucous membranes may provide a clue: They lose their normal color—red to pink—and become pale. If acute symptoms appear, you should take the dog to the vet immediately.

Expert: “Red Bell Peppers Are No Problem”

With bell peppers, it depends on the amount, but also on the color and thus the ripeness. “Well-ripened bell peppers pose no problem for dogs. Ripe bell peppers can be fed to dogs raw or cooked. Additionally, solanine levels in bell peppers have been significantly reduced through breeding,” says dog nutritionist Anke Jobi. 

It’s important to remove the stem, core, and seeds—as they also contain unwanted solanine. Bell peppers become even more digestible for dogs when cooked, though it’s not necessary. The solanine transfers to the cooking water, which is best discarded.

Health Benefits of Bell Peppers for Dogs

Red bell peppers are suitable, whether raw or cooked, as a snack or supplement to a dog’s main food. They should not be the main component of the diet, but there’s no harm in feeding them once a week. 

Bell peppers are a very healthy vegetable: They contain more vitamin C than lemons, are full of fiber, vitamins A and B, antioxidants, and provide many minerals like magnesium, calcium, and zinc. Additionally, they are low in calories and, when fed in moderation, can even help reduce obesity. 

Peppers or Chilis for Dogs?

While red bell peppers can add variety to a dog’s menu as a snack, other types of peppers, like chili and hot peppers, should not be included. They contain not only solanine but also capsaicinoids, the compounds responsible for heat. In dogs, these can cause inflammation and irritation. Spicy peppers should not be fed to dogs. 

Here’s an easy overview of the different types of peppers for dogs:

• Red Bell Peppers – fully ripe, very digestible, rich in vitamins, healthy in moderation.
• Orange Bell Peppers – also ripe, well-tolerated, high in vitamin A.
• Yellow Bell Peppers – moderately ripe, contain less vitamin A but are high in vitamin C.
• Green Bell Peppers – unripe, higher solanine content, can lead to poisoning; best avoided.
• Spicy Peppers (Chili, Hot Peppers, Peperoncini) – absolutely off-limits, as they contain capsaicin, which causes severe irritation.
