[Yorkie Luv of 3]

well,, i'm currently feeding Royal Canin with no problems, ,to my 3 Yorkies,,and have for over 2 years now,, but am looking to find Merrick locally and see about switching them over after researching online and reading all the opinions here,, but i do have a question as to kibble SIZE on Merrick???? is it a small enough bite for Yorkies to handle easily and to help keep their teeth clean and healthy too? thanks for Inputs here ,, you guys & gals are just great!! ;-)
