Well I have to agree about them spitting out the kibble...LOL
What I have started doing is giving them the Merrick wet more as a treat once a week. Like 1/4 of the can (I have 2 yorkies a 15lb teapot and a 4.5 lber) then I keep the rest in the refrigerator. Every time I have tried to mix with kibble they do spit out the kibble and just eat the wet or lick the wet and won't touch the kibble. Maybe I will start doing what the above poster mentioned and just putting a little bit on the kibble.
As for Merricks Dry I feed whatever flavor I want (I buy a 5lb bag at a time) and mix it with a 5lb bag of Canidae chicken/Rice. This way they won't get bored. That is my theory anyway...LOL
