Start with a recommendation from a friend, neighbor, veterinarian, humane society or dog trainer. Make sure your chosen pet sitter is affiliated with a professional pet sitting organization or has solid references. Once you have made a list of trustworthy and reliable sitters in your area, the next step is to call and interview candidates over the phone.
Ask what they charge, how long the visits are, if they are bonded and insured, and if they have any special skills, such as caring for birds or reptiles or veterinary experience. When calling an agency, find out how many pet sitters they employ and their days of operation. Inquire whether they charge extra during the holidays. And make sure you ask them to bring references if you decide you want to meet them in person.
