Of course, I would post this question and then my computer would go on the fritz! Just getting back online now, so thank you for all of the helpful comments.
I recently tried a sample of the Yorkie Splash & Shine. I like the scent (more of a light herbal vs. floral aroma) and I haven't noticed any allergic reactions. But after 24 hours, he's back to looking like a cute shaggy puppy. Granted, he's an uber cute shaggy puppy, but it would be nice to have more than 24 hours before he starts looking like a ragamuffin again!
Then again, it doesn't help that I haven't been able to find a groomer for him, so he's stuck with his Mom's less than professional clipping skills!
I will explore all of the suggestions! Thanks again and Happy Holidays!
