Dogs enjoy seeing their owners smile. When they master a command, they respond favorably because we are delighted and commend them for their efforts. We can’t stop watching as one pup figures out how to always give his mother a serotonin boost on his own.
Myko, a rescue dog owned by TikTok user @mykomushroom, recently released a video that has gone viral online. In the video, Myko’s mother confesses that she’s feeling a little down and asks him to smile for her. Myko is a good boy who replies by giving his cheeks a few quick licks before grinning sweetly. Check out the video to fall in love with Myko just like we did.
@mykomushroom It felt wrong to keep this to myself – leaving here in case anyone else needs it 😊 #smile #cutedogs #dogsmile ♬ Here Comes the Sun – Relaxing Instrumental Music
Myko is the sweetest dog ever, aww! It’s incredible that he can learn this instruction and can smile like a dog. Dogs are among the most intelligent creatures!
This Myko content is being devoured in the comments. Myko has the cutest smile ever, as noted by @staceywelch56 who said, “Omg! I have not seen anything this precious in ages!” and @lalagirl79 who remarked, “Aww, Myko has the best smile ever!”

Others are expressing how much they needed this serotonin boost to improve their mood. This video has been scientifically proven to lift anyone’s spirits! As one user, @littl3bit86, said, “Omg. This. This is what I needed right now. Thank you for sharing it with us,” another user, @debbiequitter, added, “Aww, this made my day. Thank you for sharing this. Anytime I feel sad, I will look at this video. Love the bowtie and, of course, Myko.”
We adore how Myko has mastered the art of the smile and is using it to lift his mom’s spirits! Given how intelligent and sympathetic dogs are, we can assume that Myko learns how to smile to cheer up his mother.
