Structure can be literal and metaphorical. Something made out of parts — like a crate or a teepee.
Structure can refer to the day to day routine.
If I build my teepee well enough and take proper care of the structure, within a few weeks it should start becoming something more substantial.
If I am clear to my dogs on what the routine is and make what they want (as The Keeper of Good Things That They Want) dependent on what I want, we all get along just fine.
