mine eats royal canine dry food. i put in warm water, to get it softer, then drain, then feed, as her mouth is soo tiny. she likes that. and in the mornings, she gets some wet food, only a little more then a teaspoon or so, for some added enrichment to her flavor pallett. we all like that ourselves, i'm sure they can get bored to, but if i mix both regularly, i know she'd only go for the wet, and that would not be good, she'd never eat kibble alone...BTDT, so it's just a treat once a day
i give her a little chicken here or there, as a snack which she of course ADORES!!!
i know some dogs can be quite picky. good luck w/ finding the right combo for success
hugs, michelle
