@bonitadan I'm mobile too and I have a client whose neighbor always makes a comment about me giving him a bath every time he sees me. It's so creepy, I hate it.
@jaceew79 There are already some good answers here. Just wanted to add a link for a blow dryer I got off Amazon that I use at home for blowing out my husky. It works great for only $80.

@manatus22 No calculation necessary, putting them together doesn't add extra length it's just the 5mm. That being said a #5 blade is probably going to be the closest at 6.3mm.
