If it doesen't work:

Obtaining the Paladin Dragon might not work if you are using Google Chrome as your internet browser. It does work if you are using Internet Explorer or Firefox.

If you are having difficulty obtaining the dragon after reaching Level 10 in Social Empires and Level 15 in Dragon City, try the following steps, or read through the comments below.
 * 1) Click on the BUILD button. Find the Paladin Dragon in the store and click "Get Dragon!"
 * 2) Allow Social Empires to open in a new window or tab (make sure your pop-up blocker allows it).
 * 3) Refresh the window or tab with Dragon City open while Social Empires is also open. The red "Requires: Level 10 in SOCIAL EMPIRES" text should now be gone when you find the dragon in BUILD.
 * 4) Click "Get Dragon!" to make the dragon egg appear in your hatchery or storage.

NOTE : Sometimes it dosen't work on Webkit engine  of  web browsers like Chrome and Safari. Try using Presto, Gecko web browser engine like Firefox, and opera.
