have 你 tried smearing some 花生 牛油, 黄油 on the back of the tub? first just put your dog in the tub but don't wash she just let she lick the 花生 butter, and praise her. 下一个 time do the same but turn on the water and wet her feet, and see the reaction and finally give her a bath. hope this helps, let me know how it goes!
