Dogs can safely eat boiled eggs. Cooked eggs, including hard-boiled ones, are a nutritious treat for dogs as they provide high-quality protein, fatty acids, vitamins, and minerals. It is important that the eggs are fully cooked, as raw eggs carry a risk of bacterial infections like Salmonella, which can harm dogs. Boiled eggs are easy to digest and can be given as an occasional treat or mixed into their regular food. However, eggs should be given plain without any seasoning, and some dogs may have allergies or sensitivities to eggs, so monitoring for any reactions is advised. Puppies can also eat boiled eggs in moderation. In summary, boiled eggs are a healthy, safe option to supplement a dog's diet, but they should be fed in moderation and fully cooked to avoid health risks.
