after setting up to start as a dog sitter with Rover, how long before my profile is available on the site??

For me, it took only about a week. It all depends on if you got all your information in and correct! After Rover sends you an email that they've completed your background check, you should be all good to go and can start setting up your profile and it should show up when people search for sitters.

Your profile is approved and active. Best of luck
