You can give them a bath as young as 8 weeks but most probley wont need it. I've been a dog groomer for many years now and I have found that my chi Blaze really only needs a bath once a month or so. You just want to be very careful an be sure to get the little ones nice an dry an make sure they stay warm after the bath.
All in the town were still asleep,
When the sun came up with a shout
and a leap. In the lonely streets unseen
by man, A little Dog danced. And the day began.
