i think it is good to shower your dog about once a month if he/she has not gotten extremely dirty.
I agree with the first answer except you probably should bath your dog instead of showering them. Also, some dogs, like Weimaraners, very sensitive skin. You should not bath dogs like these or any dogs with sensitive skin. Take them to your vet or groomer and they will use a special shampoo and groom them the right way.
