I would highly recommend waiting for a response, for a few reasons:
[1] Some sitters require meet and greets prior to booking new clients. As a pet parent, I would expect that and would want to meet the person taking care of my loved one. What if they have another dog and that dog doesn't get along with yours? What if there is an absolute deal breaker for you? (e.g., smoking in the house, no fenced back yard)
[2] Some sitters may never respond to the request if you select "book now".
[3] Booking right away sort of binds you, should the sitter accept, to that person. The great thing about Rover is that it gives you choices, that way you can find the person that fits best with you!
You should wait for a response from the sitter. They may not be available for your time of sitting, or they ?ay have a booking. Please "e respective of other people. I try to respond to an inquiry within an hour.
