Internet - Now here's an unusual canine duo: one giant and one tiny four-legged friend join forces and take TikTok by storm.

Their floppy ears hang down from their heads in the same funny way, but aside from that, these two dogs couldn't be more different.

Great Dane Buckley and miniature Dachshund Harley live together with their owner Mackenzie Delaney, who posts lots of cute videos of the two on her TikTok channel.

In the clips, you can see the mismatched duo running around the backyard, playing chase, or cuddling together. It's obvious that Harley often gets on his giant buddy's nerves – the little dog is constantly climbing all over his big roommate.

Cats Cat's tragic secret uncovered by X-ray – how could he live like that?

The little Dachshund regularly uses the Great Dane as a bed and sleeps on him as if Buckley were nothing more than a dog pillow. Buckley puts up with his friend's antics in the most gentle way.

The internet loves Delaney's videos. Her most successful TikTok clip to date recently garnered a whopping 26.3 million views and 7.3 million likes.

In addition to all the likes, the two are also getting tons of enthusiastic comments under their videos:

• "that dog has a pet dog"
• "I love how big dogs know to be careful playing with smaller dogs."
• "This poor pup gonna be thinking he's gonna grow up to be that big. It's gonna be a letdown I tell ya."

In another video, Mackenzie Delaney also shows off the rest of her animal gang. She not only takes care of Buckley and Harley, but also a cat, a bearded dragon, three chickens, and a tarantula.
