A day in the life of Sheba, a guide/service dog who accompanies her handled to college!
A peak at her sample schedule:
8:20 Kibble and Water
5:30 Kibble and Water
My guess is that Sheba goes busy (pees) approximately six to eight times a day and poops one to times times.
She will go approximately 10-12 hours overnight without going out to busy.
I always measure her water because if I know what goes it when, I can predict what will need to come out and when.
