Or at least that's what my girls tell me. They are kibble fed (Earthborn) but I've started adding a raw egg every couple of days as a supplement. They love it, but they both refuse to eat the eggshells. About the only way they will eat them is if i mush the shells up really well in wet dog food. I should add, these dogs usually get a raw chicken wing or thigh (with bone) on weekends as a treat/supplement so it's not like they're not used to chewing odd textures. Did anyone else have this issue? I'd like to just crack the egg and toss it in instead of this "crush and mash" business.
