You don't want to be running around looking for cleaning products with a wet dog in the tub, so have everything in one place before you start. You should also make sure that you're properly dressed in clothes you don't mind getting messy because you will get wet. At the very least, you will need:   Dog shampoo Treats Several towels Place one towel on the edge of the tub to keep water from splashing over the tub. The rest are for drying. Some dogs like to make a run for it during bath-time. If this describes your dog, buy a dog bath lead from the pet supply store. It's a leash that attaches to the shower's wall with a suction cup and keeps your dog in place during the bath. Replace the dog's regular collar with one that will not stain the coat or suffer water damage. A slip lead that adjusts to a struggling dog is best but the dog may choke itself no matter the restraint so monitor his breathing carefully and adjust or simply push them back when necessary. Use a squeegee or use your hand as a squeegee to force water off of the coat and body. Towel-dry him as best as you can while he's still in the tub, so you don't make a mess. Place the towel over your dog’s back, or hold it next to him and give permission to shake the water off their body. Many dogs will learn the “bath rules” and wait to shake until you have placed the towel over them to contain the water droplets.  Another type of towel to use is a chamois, which is a thin fleece-like towel that is designed to be wrung out when wet. It lessens the number of towels needed and does the bulk of the work. Using a chamois, then a towel makes drying less of a hassle. If you have a double-coated or long-haired dog, you may need to blow the coat dry.
Gather your supplies. Secure the dog in the bathtub. Dry your dog.
