MILWAUKEE (CBS 58) -- Just in time for Valentine's Day, Shake Shack is unveiling "The Love Shack."

It's a glittery pink strawberry blonde milkshake.

The fast-casual chain will donate $2 to the charity "Canine Companions" for every one sold.

The shake will be available from February 9 to February 18.

Wisconsin's first "Shake Shack" location opened in Milwaukee's Third Ward last month.
