THe first bath is stressful to them. I know that you want your pup to be really feeling comfortable in your home before bathing. It is still pretty chilly here so I blow dry my babies and they hate it...More stress... Just be carful to introduce new thigns t your baby slowly.
They sell puppy wipes to help if they are getting a bit stinky. I would wait a few more days and use the wipes. Make sure it is warm in your home, I have a little heater I use to blow n them while they are being bathed.
You will love the just bathed smell of your puppy when you do give it a bath!
