A dog named Stanley, also known as Stan the Man, has melted hearts online after a video of him learning how to show "teef" went viral on social media.
The clip, shared on TikTok in February by his owners under the username Stanleythejackrussell, features the Jack Russell proudly showing his teeth to the camera as his mom asks him to show her. It comes with a caption that says: "Stanley showing his teefs."
Since then, the pup's teeth have grown bigger, and his owners have posted several videos of him chewing on food and proudly showing his big boy fangs.

According to VCA Animal Hospitals, puppies begin teething when they're about three weeks old, and by the time they are six weeks, all of their deciduous teeth will have erupted.
A guide on its website explains that the incisors, placed at the front of the mouth, and the canines erupt first, followed by the premolars, and dogs don't have baby molars.
Then when they're about 12 weeks old, the deciduous teeth begin to fall out, and the permanent teeth begin to erupt. Usually, by the time they hit six months of age, all their permanent teeth will have emerged, and all the deciduous teeth will have fallen out.
While it's rare for a puppy to have serious dental problems, some breeds, especially smaller ones, have a tendency to retain some of their deciduous teeth, which can cause malocclusion and they will need to be removed.
The post quickly gained popularity on social media, attracting animal lovers from across the platform. It has so far received over 7.7 million views and 2.1 million likes.
One user, MenMakeMyUterusShrivel, commented: "Sometimes my lip gets stuck on my teef." And Rachel joked: "I growed dem myself!" Archie Wells added: "Oh my god this is the cutest video I've ever seen...."
