Chestnuts can be an excellent addition to your dog’s diet, and these treats have various benefits for your furry friend.

  1. Chestnuts supply your dog with protein: 100 grams of chestnuts contain about 2g of protein. All dogs need proteins to build strong muscles and support their full-body health.
  2. The fiber in chestnuts can aid in digestion: 100 grams of chestnuts contain 5 grams of fiber. Fiber can help regulate digestion, improve the colon’s health, assist with weight management, reduce diarrhea and constipation and help maintain proper blood sugar levels.
  3. The antioxidants in chestnuts will help your dog live longer: Antioxidants in chestnuts, such as gallic acid and ellagic acid, will boost your pet’s immune system and help ward off disease. The good news is that these antioxidants are found in chestnuts even after cooking.
  4. The fatty acids in chestnuts will maintain a shiny coat: Chestnuts contain linoleic acid, oleic acid, and palmitic acid. These naturally occurring fatty acids act to keep your dog’s skin and coat healthy and shiny while also boosting the immune system. 

What nutrients in chestnuts are beneficial for dogs?

Chestnuts are an excellent source of vitamins and minerals. Here are some of the top nutrients your pet can get from consuming sweet chestnuts.

  • Vitamin E: Chestnuts contain between 0.5 and 1.2 mg of Vitamin E for every 100g serving. Vitamin E helps heart and liver function while supporting your pet’s immune and nervous systems.
  • Vitamin B6: 100grams of chestnuts contains 1.02mg of Vitamin B6. This vital vitamin has a range of functions, assisting the body with proper immune and nervous system functioning while helping with red blood cell development, gene activation, and hormone regulation.
  • Calcium: Chestnuts also contain 27 mg of Calcium for every 100g or 3.5-ounce serving. Calcium in your dog’s diet will help keep their bones and teeth strong. 
  • Potassium: 1 ounce of chestnuts includes 1,200mg of potassium. Potassium in your dog’s diet will keep the heart, muscles, and nerves functioning at their optimum levels.
  • Niacin: There is about 1.7 mg of niacin or Vitamin B3 in 100grams of chestnuts. Niacin works to boost the nervous and digestive systems of your dog.

Chestnuts can pose a few health risks to dogs, especially if not served correctly or the wrong chestnuts are given to your dog.

  1. Difficulty with digestion: Due to the high fiber content of chestnuts, some dogs may struggle to digest them. This could result in stomach cramps, gastrointestinal problems, or even weakness and lethargy.
  2. Choking: Giving your dog raw chestnuts as a treat is an unsafe practice. These hard chestnuts can lodge in a dog’s system or cause your dog to choke. 
  3. Poisoning: You should also avoid feeding your dog certain types of chestnuts like horse chestnuts or conkers due to the possible presence of a harmful chemical that could poison your pet. 

What’s in chestnuts that are harmful to dogs?

Despite having some benefits for your pet, chestnuts should not become a regular food in your dog’s diet as they do carry some substances that can be harmful to dogs.

  1. Sugar: Roasted sweet chestnuts you buy at the market typically have added sugar or caramel. These types of chestnuts can be dangerous for your pet, particularly if he has a pre-existing condition like diabetes. 
  2. Sodium: Store-bought sweet chestnuts can also be salted. Too much sodium in your dog’s diet can cause vomiting, diarrhea, excessive thirst, or even kidney failure and seizures.
  3. Aesculin: Horse chestnuts or conkers contain aesculin, which is highly toxic to your pet. Aesculin is a neurotoxin and can be hemolytic, meaning it will damage your dog’s nerve tissues and red blood cells.

2. Chestnut Seed

The chestnut is itself the seed. As raw chestnuts are not safe for your dog to eat due to the risk of blockages, chestnuts should be cooked or broken up before serving to your pet.
