Before using any shampoo on your dog, protect his eyes with a drop of mineral oil or eye ointment. Do not use human shampoo since the pH for a dog is different than for you. Bring your dog into the tub. If you have a bathing tether, attach one end to his collar and the suction cup to the bathtub. Ladle the warm water over him. If you use a sprayer, use it on low and hold it gently against his coat so the spraying action doesn't scare him. When he's thoroughly wet, apply the shampoo on his back and work it gently through the coat for about 10 minutes.
Be careful not to get soap in his face or mouth. Use a washcloth or sponge to clean and rinse his face, and a soft brush to clean the paws, between toes and nails. When bathing your dog, make sure to rinse all the soap out of his coat. The rinsing cycle is very important. You want to do it twice to make sure all the soap is rinsed off. (Leaving soap on the dog can cause an allergic reaction.)
