Woo hoo! At last something I know something about! I was a groomer for several years, and had tons of dogs who didn't like the water, shampoo or blowers.

Make sure the water isn't too hot or too cold. For bathing at home, the best thing to do is to get one of the shower heads available at PetsMart or Petco. Start at the back end, all the while keep talking to her, petting her, and if necessary give treats. Lots and lots of treats!

Kind of work in a massage while you're bathing her. If you have to, put on swimmers and get in the tub with her. For a while, try to avoid getting water around her head. That can freak a dog out. We had tons of 'screamers' while I was grooming. Generally, that's all it is... screaming. Keep an eye out for signs of stress tho. Unsteady, eyes bloodshot, irregular panting, wheezing, and loosened bowels or bladder. (Gross I know, but a big sign of stress.) If any of that happens, cease bathing immediately!

But basically, just take your time with her. Most will come around eventually. Good luck!
