I would not let her coat go completely dry before brushing her.
And to be honest, she should've been brushed out BEFORE you bathed her. Now that you've bathed her w/ mats in her coat, the bathing process typically only makes those mats tighter. *ouch*
So, what I'd do now, is if you have some leave-in-conditioner or a dematting spray for her, I'd spritz her down and get to work.
She may not enjoy it, just like kids-many don't, but on the flip side I also would not let her scare herself and avoid you. Grab her, put her in your lap while you're in a chair (leash her if you must) and just go to work and get it done. She'll be fine (assuming she's not like 13 years old and is in good health)! The worst thing you could do (imo) is just let her go.
Good Luck! You can do it!
And I'd bathe her more often yourself and get her used to it. Just remember that she's going to try to run off, and just don't let her.
