i give maggie egg every day as well. she doesn't like the puppy foods so i feed her the adult food but give her the egg for added protein. i only give yolk once in a while, as it is where the fat is. yes, it has the higher protein, but it also has the high fat. so she only gets the white. I boil a dozen eggs and put them in a zip lock bag in the fridge. i cut one up for her in the mornings and I give my other dogs a bite as well, just so they are not feeling left out
she loves it and gets so excited when she sees me grab that bowl
