Yes I agree, yorkies come in all shapes and sizes.  If he is larger than what the standard states (no more than 7 pounds) it doesn't mean he isn't a full yorkie.  Also many uninformed people think that all yorkies have upright ears, and that if they have floppy ears they are mixed.  Not true!  The ears must be trained to stay up by trimming the hair on the top third of the ear, and sometimes requiring taping them up.  But many people also like the floppy eared look bc they have that "forever puppy" look.
 
There are many on here with bigger yorkies.  We affectionately call them "teapots" a play on the word "teacup", which btw there is no such classification of teacup size yorkies.  
BTW I am in Anaheim too!  Where abouts are you?  I'm at the border of Anaheim/Placentia/Fullerton.
