Well, The best shampoo in my opinion is the "PETSILK" you can order it online at petedge.com
Most importantly for now get her used to be brushed, groomed, handled... any type of brush for now and combs will be fine for now...
As she grows... and hair grows you will learn...
Start with these basics and you can be sure it is not that hard...
She can have a bath every other week for now...
Oh.... Congrats on your new baby girl !!!!!!!
