Is your dog an indoor dog or does he live outside? Are you in the US?
My dogs live inside with me. They're fed a quality diet and they get brushed on a regular basis. They really don't smell, so there's no need to bathe more than that unless they get really muddy or go in the ocean.
And some dogs just don't like water. Bring lots of his favorite treats with you, so he doesn't want to run away. Keep a leash on him if you have to. Keep it as positive as possible and make it a good experience for him instead of something he feels he needs to run away from.
