[Maximo]

Full disclosure, I am a retailer of grooming products.

I used Hartz when I first brought Max home, my first Yorkie. It made him smell like yucky, wet dog. Good products are worth the price.

Each Yorkie coat is different and environmental factors can influence which product is best for your pup.

My favorites for my boys:

1. Bio Groom Oatmeal shampoo followed by the awesome Bio Groom Silk Creme Rinse

2. Spa Lavish Facial Scrub for the head. It's easy on the eyes (tear free), but cleans thoroughly and rinses quickly and easily.

3. Isle of Dogs "Coature" line

4. Vellus products -- pricey, but fabulous

6. Les Poochs Hypoallergenic shampoo and conditioner -- also pricey, but can be diluted to make the bottles last. I like to put the conditioner on thick for my full coat guys. Probably not necessary for a puppy.

Edit to add: Coat Handlers is also soap free and very gentle, loved by many Yorkie breeders and exhibitors
