Frequently Asked Questions
What is the difference between chestnuts and horse chestnuts?
European/American chestnuts (Castanea species) are safe for dogs. Horse chestnuts (Aesculus hippocastanum, also called conkers) are toxic and can cause vomiting, drooling, and abdominal pain. Never feed horse chestnuts.
Can dogs eat raw chestnuts?
Cooked chestnuts are safer and more digestible. Raw chestnuts are harder and more bitter, and may be more difficult to digest. Light boiling or roasting without seasoning is recommended.
Are water chestnuts the same as regular chestnuts?
No — water chestnuts are an aquatic vegetable (Eleocharis dulcis), not related to tree chestnuts. Water chestnuts are also safe for dogs in small amounts, raw or cooked, plain.
Are chestnut stuffings or chestnut desserts safe for dogs?
No — chestnut stuffings and desserts contain butter, salt, sugar, and often onion. Only plain, simply cooked chestnuts without any added ingredients are safe.
