Sleep
Half your dog's life happens with their eyes closed.
Poor sleep shows up as reactivity, weight gain and early cognitive drift long before anyone calls it a problem. So we measure it like any other system.
A sample week
Total sleep (light bar) and deep sleep (dark segment), illustrative. Thursday's dip followed an evening visitor and a late meal.
What we change
Light
Bright mornings, dim evenings, and no screens facing the bed, circadian signals dogs read as clearly as we do.
Temperature
A cool sleeping surface with a warm retreat nearby; heat is the most common cause of a broken night.
Sound
Predictable low masking rather than silence, so household noise stops triggering full arousals.
Last meal and last walk
Both moved earlier where the record shows late-evening activity fragmenting deep sleep.
