Dogs can eat yam. Yam is a relatively safe food for dogs and it also has some nutritional value. Yams are rich in dietary fiber, vitamins and minerals and may have certain benefits for your dog’s digestive health. Feeding yams in moderation can serve as a healthy addition to your dog's diet.

If your dog usually eats a diverse diet and has a good adaptability to new foods, then It is okay to feed yams in moderation. But if your dog has special health issues or dietary restrictions, it's best to seek advice from your veterinarian before feeding.
