You can use \removeunwantedpsaces to remove preceding spaces before
your command and \ignorespaces to gobble spaces after your command.
A faster version of your macro is:
\def\MyFunction
{\dosingleempty\doMyFunction}
\def\doMyFunction[#1]%
{\removeunwantedspaces\executeifdefined{myfunction:#1}
{\getvalue{myfunction:default}}}
\setvalue{myfunction:1}{\medspace dog }
\setvalue{myfunction:2}{\medspace cat }
\setvalue{myfunction:default}{\ldots}
