As for drying, typically you would want the puppy on a safe surface, your lap or a grooming table, or even a counter that is safe and then blow dry the pup, using one hand on the dryer, one hand on the pup... as the pup gets older and less wiggly you can actually use one hand to comb/brush and the other to blow dry. UNLESS you get a dryer 'arm' which holds the dryer OR if you are lucky enough to have HELP bathing! LOL
Blowing coat varies, but typically will start between 7-10 months and could last a few months... we are here for you!!
As for the cotton balls... LOL that seems like a cruel joke or something, I could NEVER, NEVER get those stupid things to stay IN her ears!! I am somewhat careful and actually use a hand to kind of 'close down' her ears when I am cleaning that area. I also use an after the bath "liquid" that I squirt in her ears and massage it around. She shakes out an excess, it dries up any water that may have gotten in the ears!
As for the ear hair, some people never have a problem with it, others do. Tillie ended up getting a HORRID ear infection from baths at the groomers (and them not taking care of her ears!). It was BAD, black, nastiness in both ears and SO painful she would cry when we touched them. The vet tech had to hold her while the vet cleaned out some of the gunk so that the ear drops could actually get IN her ears!! Since then I check them everyday when I brush her out do the drops after every bath (every week or 2) and then every few months actually trim out some of the hair that grows IN the ear and some on the very front (you can't SEE any difference, just gives the ears some breathing room!). Once we got that first ear infection under control we started cleaning the 'dead' hair out of her ear canals with a gripper tool thing... we do NOT 'pluck' the ear hair, only taking out what is naturally shed!! Now adays (she's nearly 2!!) When I trim the hair every few months I actually just use my fingers and go in as 'deep' as my stubby fingers can go and grip and pull out any dead hair, I do this several times until nothing it coming out. It does NOT hurt the pup AT ALL, you just have to be firm and just do it, making sure you don't get any hair that is still rooted to thier skin!!
As a puppy you just want to flip her ears back and check them for now, you'll see when they are getting really hairy and you can DECIDE if you want to trim the hair back a bit or not. Like I said, not all havs have issues with ear infections...
btw, she hasn't had another ear infection, since I took over ALL of her groomin!
