It is imperative that you visit your local shelters in person to see if your pet has been turned in. Take a descriptive picture of your pet with you and be prepared to leave it. Do not depend on the shelter staff on getting back to you. They are often overwhelmed, the sheer volume of lost and found reports they are required to deal with often exceeds their staffing. You really need to return to the shelters regularly to look for yourself. Commonly the shelter’s log entry does not match your verbal description. You may describe your pet as “tan” and the shelter may have logged in a found pet as “light brown”.
