I was working on a project to create deformations for a quadruped and i ran into a situation where it wasn't too easy drawing zremesher guides when the Dog was is in a standing position. So the tip here is to rotate the arms and legs outwards like the dog was flying. This helps to draw the zremesher guides a little easier.
Here are some of the rough topology images i created: (original character,design,model)
