What happens if a dog eats a salted duck egg?

Salted duck eggs contain a lot of salt and cholesterol, and long-term or large feeding can cause these problems: first, too much salt upsets the gut, causing diarrhea and vomiting. Second, high salt burdens the kidneys, and if the dog already has kidney disease, salty food worsens the damage. In addition, the high cholesterol can raise blood cholesterol and heart-disease risk. Finally, if the egg is spoiled or toxic, the dog may show poisoning such as vomiting, diarrhea, and toxic shock.
