There may be a few occasions in your dog's life when you have to bathe him, but he cannot get wet. This might happen after surgeries or even as a matter of convenience. If you've ever been camping with your dog, you know what it's like to be without water and yet have a filthy dog who needs to be cleaned. With a little bit of preparation and planning in advance, you can bathe your dog without getting him wet at all. This will at least get him by temporarily until he can have a full bath with shampoo and water. Bathing your dog without water is also quite helpful when you need to spot clean your dog. This means he only has a few areas that are dirty rather than his entire body.
Depending on the reason your dog needs a bath without water, he may be a little apprehensive for you to touch him in any way. If your dog has just had surgery, he may be sore, tender, and tired. If he has just gotten into something that he shouldn't be involved with and you have no water on hand to bathe him, he may be a little nervous feeling like he's done something wrong and could potentially be in trouble. Either way, talk to your dog in a nice soothing voice to make him comfortable and make his bath without water quick and painless for him.
Bathing some dogs is im-paws-ible. Don't put your dog through a pawful experience having to deal with water for every one of his baths. Give him a dry bath without water before your best friend becomes furociously stinky.
