I go to school for 7 hrs a day and I have a new puppy. Is it okay if someone lets it out once while I'm gone? I get home at 2:20, is this cruel for the puppy. What if I leave training pads for it. Im planning on leaving her crate door open and fencing off a puppy-proofed area in my room. Can training pads replace someone chcking on it? Our budget is tight, but we are trying to do what's best for the puppy.:confused:
