How many chestnuts can a dog eat? You can feed small quantities, up to five chestnuts, once a week or so. If your dog loves them as a treat on their own, you can use them in training sessions or crumble chestnuts over their dinner as a topper. Of course, avoid pre-cooked chestnuts that have been prepared for us humans, with salt or sugar added.
Can chestnuts make a dog sick? Chestnuts contain starch, which dogs are unable to digest in the same way that humans can. Too much starch is likely to cause an upset stomach, vomiting, or diarrhea. In severe cases, this can even lead to pancreatitis.
How toxic are chestnuts? While cultivated or wild sweet chestnuts are edible, horse chestnuts are toxic, and can cause digestive disorders such as abdominal pain, nausea and vomiting, or throat irritation.
Are wild chestnuts bad for dogs? Why are conkers dangerous to dogs? There are two reasons for this. Firstly, the large nuts could cause a blockage in your pet’s stomach. Secondly, they contain a chemical called aesculin – found in all parts of the horse chestnut tree, including the leaves – which is toxic to dogs.
