The Facebook video posted (below) shows Maxwell dressed up as a police officer and telling his litter sister to go back inside.
It was picked up by the Pride of Britain Facebook page no less, and has since been shared 5,500 times and had 25,000 likes.
In a comment on the post, the children's Dad said: "As the parents of Maxwell and Millie, we’d like to personally thank each and everyone for all your comments and likes.
"They both couldn’t understand why so many people are still going out, so wanted to create a short video to try and get the message out.
"Both Maxwell and Millie are so happy how many people have viewed and commented.
"Stay safe everyone."
The pair even got a special patrol car sent out to them by GMP to thank them for sticking to the rules and educating the public - all while putting a smile on everyone's face!
