Abstract: A selectable washing system, particularly useful for washing of dogs and other pets, is provided. The selectable washing system specifically relates to an improved, multi-port, multi-valve selectable washing system that allows individual selection of multiple solutions individually to create a custom mix of solutions. The washing system includes a manifold having a plurality of inlet openings and an outlet opening disposed therein. Each of the inlet openings in the manifold is connected to a corresponding solution supply container by one or more valves. According to one presently preferred embodiment, both a needle valve and shut-off valve are positioned between each manifold inlet and its corresponding solution supply container. The output of the manifold is connected to a venturi valve which draws the custom solution mix into a stream of water to be applied to the coat of the pet in diluted form.
