1. What kind of shampoo do you use?
We use Cloud Star Buddy Wash, Rinse, and Splash: http://www.cloudstar.com/5DD044CB6F4...A7CA975DA092BD barkaholics.biz (Erin, I think?) also carries it.
2. I am planning to have my baby sleep in my room and was going to pick up a baby pen like this one:
I think that playpen would be fine. We have this one: http://www.walmart.com/catalog/produ...uct_id=1762412 and you can use only 4 panels instead of 6. Makes a nice square.
3. What chew toys are good for the puppy?
Franklin loves soft plush toys, anything that squeaks, ropes, and bully sticks.
4. What kind of harness is adequate? If I wanted to purchase one before I picked him up, being 4 lbs, what size should I be looking for?
The first harness we got for Franklin was just one from Petsmart - it measures from 8"-12": http://www.petsmart.com/product/inde...ductId=2751279 He's 7.5lbs now and growing out of it so we've ordered a silk harness from Cindy: http://www.yorkietalk.com/forums/sho....php?t=116672&
Hope this helps!
