i fed my yorki for about 5 yrs with royal canin and thought it was great. kibbles are small and i thought he liked it. but now reading all of this maybe thats why he's been itching and scratching. may be he developed an allergy. he also is a big yorki, 12lb. and his doctor says that he is not fat but buffed.i have tried today mixing his kibbles with a "evengers super premium dog food". we'll see.
