Actually we make sure she gets the oportunity to use the bathroom every 2 to 3 hours around the clock, it works out well for us since there are three of us in the house and one works mornings, one works swing, and one works graveyard. Since we have had her she has had 2 accidents, one was in her crate the first night, and one was on my son while he was trying to take her outside yesterday.
We can't really put food out at all times, my other dog will eat it before she gets a chance, so every 2 to 3 hours, we offer food to her inside her crate and after 5 minutes remove her. Hopefully that is an acceptable compramise.
I will confine walks to the back yard at least untill we get shots, that way the leash will not be needed, and we have time to find a harness small enough, or give her some time to get a little bigger. i looked at a few harnesses yesterday but even the ones for kittens were too big. Same thing with jackets, and boots. They just don't make them small enough for her.
While we have several toys for her, such as a little kong, and a few squeeky things, we have found Zara is partial to socks, and empty paper tubes. It is the cutest thing watching her trip up as she is dragging a sock 3 times her size around the house.
