I'd also say if you pup did break an egg it would prob only happen once, can't imagine they'd like the taste.
EVERYTHING likes the taste of eggs. Eggs are delicious = a universal truth. I have yet to meet a dog or cat that doesn't love eggs.
Not to mention wildlife, chickens will eat their own eggs and once they realize that, can't be broken of the habit - heck, I once saw one of my dairy goats eat an egg that was laid in the hay rack!
If you ever doubt this, go ahead and crack an egg into your dog's food dish.
CAUTION: Don't let them see you crack it. Seriously. For a bunch of them, realizing "Oh, that's what's in there!!" is all it takes. I'm not joking
