Great advice from a very legitimate organization. I belong to PSI and if you are a ‘real’ pet sitter this is an association to be part of. They are really targeting the advent of DogVacay and Rover . com here. I would caution using anyone that wasn’t a full time pet sitter or boarding facility and that does not have credentials of any kind. There may be some professional full time pet sitters using these sites but I’ve chosen not to, as it just opens the door for anyone.
