Adult food for puppy

My 8 month old Malte-Poo is a very picky eater...I've tried three different types of puppy food and can't seem to find any she likes! I want to give her high quality food and have tried Natural Balance, Nutro, and Purina One. She hates them all and will only eat any if I mix a tad of canned <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=22&k=dog%20food" onmouseover="window.status='dog food'; return true;" onmouseout="window.status=''; return true;">dog food</a> with it. I confess, I had been feeding my other dog (lab/german shorthair mix) a low grade food because I really didn't know there was such a difference. I'm changing her over to a better food now too.

Anyway, Puppy LOVES Josies cheap food, anytime there is any left in josies bowl when she's done eating, Pebbles is all over. I don't want to feed her the crappy food, but I do want her to eat! I was thinking since I'll be changing Josie over to Purina One instead of the Ol Roy and Gravy Train, I could just let pebbles eat the adult food even though technically she's still a pup??

 

At 8months of age adult food should be fine for her.
