If it was my choice, my dogs would get bathed whenever I feel the need arises. But I'm not allowed. After I move out I will be able to bathe my new dog whenever I want.

besides dogs have nateral oils in there coats and too many baths will destroy the protective oils, and give them a bad coat, 2-3 times a year is lots.
I was watching that Hagen's pet show, and it said that a dog shouldn't need a bath more than twice a year, and if it does, then it should not exceed more than once a month because you could seriously dry out a dog's skin (unless used with oatmeal or anti-itch shampoo), making it itchy, or ruin a dog's fur, making it dry and unmanagable.
