Thank you so much for your advice! So what happens if someone doesn't pick up their dogs or turns out to be a crazy? Haha do I contact rover support? And would it be considered an emergency?

So this is my first booking and I did not want to reject it. The owner sent me 2 requests both different dates. I responded to the one that I was available for as the other one I was watching a friends dog already and put as unavailable on my calendar. She never responded to me saying I was unavailable to sit for the first request. But she did respond to me accepting the second request. Then last minute she asks if we can change it to the first dates and I told her unfortunately no I can't. Now tomorrow is the day she drops off her dogs and I left her a message asking for care instructions and a list of things she would need to bring (food, collars, leashes tags) and stuff she could bring if she wanted (beds, crates, blankets, toys). But she never responded and only messaged back saying she would be here around noon. I have no care instructions for the pups and they both have extreme anxiety. What should I do? She seems very unresponsive. She's also declined meet and greets. The booking was booked a couple Of weeks ago and I start watching her dogs tomorrow
