I feed Merricks also. I buy a 5lb bag of whatever Merrick flavor dry I want and mix it with a 5lb bag of Canidae. Then as a treat - once a week I feed Merricks canned. Whatever flavor. Mine really like the Thanksgiving dinner, Granny's Pot Pie and they also like the Working Dog Stew BUT Izzy got diahrea after that one so I won't feed that again. It may be to rich for her.
I love Merricks and Canidae. I won't feed anything else (unless of course there is a recall

)
