Can dogs eat hazelnuts?

Despite not technically being toxic, hazelnuts pose several health risks to dogs. We don't recommend feeding your dog any. To start, their small, round shape makes them a choking hazard, especially for smaller breeds.

Dogs may also struggle to digest hazelnuts, leading to gastrointestinal disturbances like vomiting, diarrhoea, or constipation. Hazelnuts are also high in fat. Excessive fat intake in dogs can lead to pancreatitis, which is not only painful for your pet but can also lead to other serious health issues if not addressed promptly.

So, what do we do if our dog sneakily eats hazelnut when we’re not looking? Look for any signs of discomfort, and if you spot something amiss, call the vet ASAP.

If your dog eats hazelnuts and is showing signs of illness such as lethargy, diarrhoea, or vomiting, reach out to your veterinarian immediately. If they require veterinary care as a result of eating any unsafe foods, dog insurance can help cover the cost of treatment.

Can cats eat hazelnuts?

While hazelnuts aren’t labelled as toxic for cats, they do come with potential problems. First off, their small, round shape is a choking hazard, especially for petite kitties!

Hazelnuts might take our kitties on a not-so-fun adventure, causing an upset stomach or even a chaotic episode of diarrhoea.

The nuts are also high in fat. While fats are essential in diets, too much can lead to pancreatitis, which is inflammation of the pancreas. It’s as unpleasant as it sounds and can lead to other health issues if not addressed swiftly. Plus, nut allergies can be a thing for cats too, leading to all sorts of itchy and scratchy scenarios.

If your cat eats hazelnuts and is showing signs of illness such as lethargy, diarrhoea, or vomiting, reach out to your veterinarian immediately. If they require veterinary care as a result of eating any unsafe foods, cat insurance can help cover the cost of treatment.
