That's my opinion as well, I've never had a problem. During summer and early fall when our chickens are laying overtime, my dogs eat lots of eggs. I either hard boil them, microwave several inside a large Kong (drape a papertowel over the top hole so it doesn't explode!), or just crack and serve raw.It is totally animal protein. 75 calories each. I cannot see any reason why a dog could not eat 4 a day.
Hard boiled might cause more gas. I guess. Maybe. You can nuke them, fry them in butter, scramble them with milk and fry in butter, or feed them raw. You can make them for your breakfast and eat the whites and give the dog the yolks. Egg is like the perfect food for dogs.
