How to user can see their own records not all records ??

Hi, Please help me out!
Firstly you can register this site and go to Pets (page) there is a form and after submitted data will be showing in Pets records page.
Please help me, I want to show specific data to user, means if someone fill contact form data in that form and data will be show Pet record page, but the problem is when I generate shortcode in contact form db, all user’s data who logged In or not logged In and entries are showing, I want to show only specific data by the user who logged In and filled their account not all users data. Please anyone guide me what can i do.

Thanks.
