Dog whistles use language that appears normal to the majority but communicate specific things to intended audiences. They are generally used to convey messages on issues likely to provoke controversy without attracting negative attention. One example may be the use of a phrase such as "family values" to signal to Christians that a candidate would support policies promoting Christian values without alienating non-Christian supporters. Another may be the use of the phrase "international banks" to signal to racists that a candidate is anti-Semitic without alienating non-racist supporters. Accusations of dog whistling are, by their nature, hard to prove and may be false.
