Should I leave food down when I leave my dog alone?

Feeding a proper meal shortly before you leave, rather than leaving dry food available all day, keeps a more predictable routine and makes it easier to notice if a dog's appetite changes, which is a useful early sign of stress or illness.

Reserving a portion of the regular meal for a puzzle feeder or slow feeder bowl, set out right as you leave, extends mealtime into useful occupied time during the early, often hardest part of an absence, without changing the total amount fed that day.

Puppies on multiple small meals a day may need a midday feeding arranged through a walker or family member, and any dog with a medical condition requiring a specific feeding schedule should follow their vet's guidance rather than a general rule about food during alone time.

A dog that normally finishes a puzzle feeder eagerly but suddenly leaves food untouched during several separate absences is showing a change worth paying attention to, whether the cause turns out to be stress, a shift in routine, or an underlying health issue. Keeping a rough mental note of typical eating patterns during alone time makes it much easier to notice when something has genuinely changed rather than dismissing an off day as unremarkable. A pattern lasting more than 2 or 3 consecutive absences is generally worth mentioning to a vet, even if the dog otherwise seems fine.
