If you want your dog to enjoy getting a bath, make bathing an enjoyable experience.
Start by feeding your dog in the tub. And when that's no big deal, give him treats when turning the faucet on and off. As you progress to bathing, make sure your dog is hungry, and give him treats and praise for good behavior.
Make sure the water temperature is fit for a baby, and use a tearless shampoo for pets. A tiny bit of cotton pressed gently and not too far into the ears will keep water out, and use a washcloth on your pet's face to work around the eyes and mouth. Massage and praise your pet during lathering and rinsing. Finally, give him a special chewy treat after every bath to further associate good things with the bathing experience.
