Yes that is what I meant.

Probably that is ok as well. The main problem is that it is impossible 
to inline the "bark" function so one part of the code is in a different 
place, which may mean it is clearer to put the reference to that 
function up next to it too.

Generally I don't think a generic function should be written until you 
have at least 2 instances where it is used.
