I know that rusty is a German Shepard, but I need help! I have tried 4 different foods and he still sticks his nose up. He has been on the costco brand , , a expensive brand from the feed store (unfortunately i can't think of the name) science diet. and in my desparation to find SOMETHING i have just tried Purina one. SO My question is if you have a picky eater is it better to continuely try new foods (of coarse mixing them to whine him off and not upset the tummy) or to stick with a giid brand of food and add a few things to the food? I don't think it is a tooth or gum problem. i have checked them and they look fine, and he has no problem munching on the ocasional bone. also he does have an apitite, he just turns up his nose at dog food. i have been telling the boyfriend telling him Rusty is playing us for goodies. but at this point i am getting a little concerned about his weight. Thank you for your help!
