I think if you research and start to intoduce her to a really good food (slowly) as soon as you get her that will be half of your battle done!!!!
Other than that just wiping the wrinkles and drying them, and giving her lots of cuddles should be all you need to begin with. I don't wipe my bullys butts unless they need them wiped. Daddy's tail means I have to do it a lot more often than Maggie's.
My advice would be just to keep viisting this site .... asking questions as soon as they pop into your head!!!
Has the breeders sent you any pics of your girl??? We LOVE photos on here so please share!!!
