Fish is also great for a dog's coat and isn't too fatty. I feed sardines regularly as well as mackeral. I have tried raw salmon heads too but the dogs found the a bit tough to get through.Originally Posted By: JoJo's MumThanks guys. I give the egg to make her coat shiny and also cause she seems to like it. Will cut to egg down to maybe a sunday treat? More JoJo is over weight and I cant keep weight on Jesie!
