@zemastruve Not sure why you were downvoted, but here's a little info to help.
Salt does the same thing to dogs that it does to human skin, which is to say that it's very drying. Your dog's skin will become way too dry at some point, which usually leads to an overproduction of skin oil from glands that aren't getting or maintaining enough natural oil. So you end up causing a problem by too much exposure to salt.
So, you'd want to wash after salty swims with a moisturizing shampoo, and you may want to look into a dog conditioner. Don't use people stuff, just try the ones made for dogs.
For the dryer, using a hair dryer on a lower speed helps a bit. You might also want to look into a Happy Hoodie (a head wrap type of thing that covers a dog's ears during blow dry to reduce the noise a little and provide comfort). However, they don't work for everyone.
But one thing I've done is simply use the hair dryer on myself while showing my babies that it's not harmful. Just pointing it directly at myself while they're in the room (while also being calm) seems to work. But give it time. She just may be afraid and there's not much you can do.
And short-haired dogs have the same needs - the skin needs to dry
thoroughly. You'll run into a LOT of problems by not making sure that her skin is thoroughly after bath time or swimming.
I can't stress this enough - make sure her skin is
completely dry after exposure to water. Using an absorbent towel first to soak up a lot of the water, then using the hair dryer should also help to reduce drying time and get your dog dryer sooner.
Good luck!
