How often can I give my dog eggs as a treat? Are they safe daily?

Eggs are fine as an occasional treat, but it's not something that Andy should get daily. The only food that a dog needs is a high quality dog food, which will provide him all the nutrients he needs to be healthy. Adding additional food on top of that will lead to extra calories and weight gain. Weight gain leads to obesity, which in turn leads to its own health problems such as heart disease, diabetes, and joint problems. It would be fine to give him a boiled egg (no shell) once or twice a week as a treat. You can also give him a scrambled egg, but make sure it's egg only and no seasonings etc. Good luck, I hope this helps!
