There should be a little check box under each pet. After clicking the boxes on the pet(s) you want to move, scroll down to the bottom of the page, and you can pick which group you want to move them to. To speed up the process with larger groups, you can add "&pageSize=1000" (remember to capitalize the S. You can also put any other number) to the end of the URL at the top of your screen. c:
