Why is Hazelnut Bad for Dogs?

There are several reasons why hazelnuts should not be fed to dogs. First, hazelnuts can cause choking in dogs due to their hard texture. They may also result in obesity, bladder stones, sodium ion poisoning, and pancreatic problems. Look out for the below common symptoms, such as

Hard Texture: Hazelnuts are oval, hard, small, and capable of getting stuck in a dog’s esophagus and causing choking.

Salted Hazelnuts: Commercial and store-bought hazelnuts are full of salt content. Large amounts of salt do not suit a dog’s anatomy and cause seizures and kidney failures. In addition, the salt content in the hazelnuts bought from the stores can irritate the digestive system.

Nut Allergies: Some dogs are intolerant to nuts. This can cause nut allergies in them. Some symptoms like swelling, itching and gastrointestinal issues.  

Fats: High-fat content in hazelnuts can cause obesity and pancreatitis, which may lead to fatal conditions.

Mycotoxins: Mycotoxins are a kind of fungi that causes seizures in dogs. Hazelnuts have a high moisture content that aids the presence of fungi. Also, when the nuts are stored in dark, moist areas, there are more chances for the fungi to grow. Mycotoxins cause vomiting, indigestion, and diarrhea in dogs.

Obesity: Like any other nuts, hazelnuts are also rich in fats. The fat content in the nut leads to weight gain and obesity. As a result, the extra fat affects the dog’s energy levels and leads to issues like diabetes and joint pain.

  • Vomiting
  • Diarrhea
