Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Hazelnuts are not toxic to dogs, but they are not recommended as a regular treat. Their small, round shape makes them a choking hazard, particularly for small and medium-sized dogs. If swallowed whole, they can also cause intestinal blockages. Hazelnuts are high in fat, which can contribute to weight gain and may trigger pancreatitis if consumed in large quantities. Some dogs may also experience digestive upset including vomiting and diarrhoea after eating nuts. If your dog eats one or two hazelnuts accidentally, it is unlikely to cause serious harm, but monitor for choking, gagging, or signs of digestive distress. Avoid flavoured, salted, or chocolate-coated hazelnuts, which add further risks.
What You Should Know
While hazelnuts is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
