You have to think of what's frightening her, slipping around in the tub, loud noise of water, water temperature too hot, too cold, although most people get it way too hot. I use a plastic tub in the kitchen sink so Joey doesn't slip around, I test the water with my forearm, puppies especially cannot deal with hot water, and it should feel tepid, or lukewarm. If she's too big for the sink, I would get a baby bathtub and place that in the larger bathtub, make the experience as pleasant as possible. An arm spray attachment for showerhead would work well, and again test water before spraying. I cover Joey's ears folding the flaps of his ears down with one hand and spray with the other. I warm up a towel, and afterwards he veggies out in a warm towel covered head to toe. I think this is his favorite part.
