Print it as often as you like. Leave anything you do not need blank. You can also fill in the top fields by hand once and copy the sheet for later weeks.
Keep it on your phone with PetDose
Paper works well for a short course. If you would rather keep the log on your phone, PetDose is a free iPhone app for pet medications, meals and walks. It shows what is done, what is due and who gave it, warns you before a second dose, and sends a reminder only when something is overdue. Free to track, no account, and everything stays on your phone. Pro adds full history and a vet visit report you can send or print.
