编辑链接仅从数据库表PDO返回最后一行

我正在尝试从表中连续编辑数据。我有一个查询设置，只显示每个用户他们的狗，他们将能够编辑有关该特定狗的信息。我可以让编辑显示在每一行旁边，当我点击＆＃34;编辑＆＃34;编辑的表格确实出现了，但是在查询中填写了最后输入的狗，而不是我要编辑的狗：如果用户有三只狗而dog_id是6,7,12只有关于将显示12，我需要能够挑选任何狗并编辑他们的信息。任何人都可以帮我弄清楚我做错了什么？

以下是查询用户狗的代码：

  <table border="1" cellspacing="0" cellpadding="2" >
    <thead>
        <tr>
            <th> Your Dogs </th>
            <th> Breed </th>
            <th> User </th>
            <th> Dog Id </th>
        </tr>
    </thead>
    <tbody>
        <?php
            include('scripts/check_user.php');
            $stmt = $db->prepare("SELECT * FROM dogs_info WHERE id=:log_user_id");
            $stmt->bindPARAM(':log_user_id',$log_user_id,PDO::PARAM_INT);
            $stmt->execute();
            for($i=0; $row = $stmt->fetch(); $i++){

        ?>
        <tr class="record">
            <td><?php echo $row['dogs_callname']; ?></td>
            <td><?php echo $row['dogs_breed']; ?></td>
            <td><?php echo $row['id']; ?></td>
            <td><?php echo $row['dogs_id']; ?></td>
            <td><a href="dogform_edit.php?dogs_id=<?php echo $row['dogs_id']; ?>"> edit </a></td>
        </tr>
        <?php
            }
        ?>
    </tbody>
    </table>

以下是点击编辑链接的结果代码：

如果有人可以提供帮助，我会非常感激！我对此非常陌生。
