Can Dogs Eat Chestnuts?
Yes, in moderation — plain, cooked chestnuts (sweet chestnuts) are safe for dogs. They're lower in fat than most nuts. Never feed horse chestnuts (conkers), which are toxic.
Sweet chestnuts are safe — horse chestnuts are toxic
Cooked sweet chestnuts (the kind humans eat) are safe for dogs and lower in fat than most nuts. They provide fiber, vitamin C, and potassium. However, horse chestnuts (conkers) found on the ground are toxic and can cause vomiting, diarrhea, and neurological symptoms.
