Halloween isn't just celebrated by humans – dogs love dressing up too! Happy, a Golden Retriever puppy, did just that, and her adorable costume is melting hearts left and right.

In the clip, Happy is first shown without a costume. She then runs away and returns wearing her Halloween outfit.

It's instantly recognizable: the little puppy is meant to be Dumbo, the flying elephant.

To achieve this, Happy wears a tiny hat on her head and the iconic large ears that allow the small elephant in the Disney classic to fly.

With big eyes, the youngster looks into the camera, appearing slightly serious in its costume, but hearts melt nonetheless.

The video has so far garnered 2.5 million views and more than 150,000 likes.

"She says she'll grow into the ears," her owner jokes in the caption.

The Dumbo costume is just the tip of the iceberg. Happy's owner absolutely loves dressing her dogs in all sorts of outfits – even in everyday life.

Before Happy, Golden Retriever Ace and the late dog Sunday also had to endure a few ensembles. And Happy herself is already a "repeat offender."

So, after her Dumbo costume, she was allowed to showcase another outfit.

Just a few days ago, the fluffy four‑legger was spotted in a teddy bear costume.

"I think it's bear-y cute," the viral video's on-screen text declared.
