i have my yorkie and my kitten on Wellness core. My yorkie is doing fine on it. My kitten however had the most terrible gas and poop smells. she's on her second 3lb bag now and the smell is gone.
switching to a higher quality food sometimes takes a few weeks to get the results you want. Their digestive system is adjusting to the new food and "flushing" out the old food so that is where the smell comes from. Wellness is great so if you stick with it a little longer you may see and smell better results.
However every dog (and cat) is different so you may not get the same results for all your yorkies.
