one line definition of a variable conditional on the output of a logical test

In bash programming I've always defined conditional variables in the following long hand way dog=1 if [[ $dog -eq 1 ]] ; then cow=1 else cow=0 fi This is obviously incredibly inefficient. In MATLAB I can do the following cow=(dog==1) i.e., one line instead of five. Is there an analogous way to do this in bash? Thanks for any advice.
