Bottled water actually contains certain "bacterias", despite what everyone useually thinks, the types depend on where that water comes from and the filter they use to clean it...The filters will clean out some bacterias and leave others.
Most tap water has fluoride in it, and hard water contains calcium and magnesium and soft water contains sodium and potassium.
Hope that helps some, I don't know of a definite answer as to which is better for dogs, I usually fill Duke's water bowl with tap but he gets bottled water if I take him somewhere with me.
