My Rudy gets bored very quickly with his food! So my new ideas was to mix all of his favorite brands that he seems to eat for a while ... So now I mix Evo Red Meat with Natural Balance Sweet potato and Venison and Solid gold Bison... Now he will munch on his food all day long without me having to hand feed him... seems to be working for us...and he is finally putting on some ounces
 
Maybe you could try mixing your little ones favorites!!!
