Not sure if this will help with Roxie but Cissy had the same stinky problem. I bath her every weekend but after a couple of days, she smelled like she hadn't had a bath in months. I tried different shampoos (no difference) and it wasn't until I tried the Yorkie Splash/Shine that I noticed a BIG difference. You may want to give it a try and see if it helps Roxie as much as it did Cissy. Cissy now smells like the sweetie she is.
I am so thankful we now have this product. Good Luck!
