My gal will sometimes go on a 'hunger strike' because she is so bored of her kibble. I only feed her dry kibble, as recommended by her breeder -- plus it keeps her teeth white as snow! (raw and some 'very high quality' brands makes her very runny and vomity -- I feed her mid range Nutri-Source). I found that if I mix in a tablespoon of peanut butter she will scoff up her meal that she previously turned her nose up to, so I know its not because she isn't hungry. But is that ok to give processed peanut butter every day?? I would like to add a little something in her food to encourage her to eat but do not want to add anything with any additives or unnatural things to her diet; since I spend a small fortune on her food and all-natural supplements -- I would hate to have all that go to waste, just so she will eat -- because then I might as well save my money and buy the cheaper brand. She is 120 pounds (Great Dane) so she is somewhat on the lean-side -- no ribs are showing, but I think she could add a few more pounds and look better -- if she would eat the recommended 6 cups daily, every day, I'm sure she would put on a few more pounds -- as it is she ranges from 3 to 6 cups daily. Suggestions? Thx! (of course I wish I had her resolve )
