California Woman Thought She Adopted A Chihuahua, But Then She Got A Big Surprise

While browsing pet adoption listings one day, California resident Susan spotted a tiny dog with big, soulful eyes that immediately stole her heart.
With her small size and adorable, expressive face, the pup looked just like a classic Chihuahua. Susan didn’t hesitate. She headed straight to the local animal shelter, excited to meet her in person.
The moment they met, it was instant. Susan just knew she’d found her new best friend.

Susan couldn’t wait to start this new chapter, so she adopted the little pup and brought her home.
She decided to name her Miss Frizzle, a fun nod to the quirky character from The Magic School Bus. It was perfect: playful, curious, and full of personality, just like the pup herself.
But not long after Miss Frizzle settled in, Susan’s roommate, Sarah, started noticing something… a little unusual.
Pretty soon, both Susan and Sarah started wondering, “Wait… is she really a Chihuahua?”

Susan had assumed her new pup was purebred, or at least mostly Chihuahua, since she hadn’t paid much attention to the breed info at the shelter. But Sarah wasn’t buying it.
When Miss Frizzle started zipping around the apartment with surprising energy and agility, it clicked for her: there had to be some Border Collie in there.
At first, Susan laughed. After all, Miss Frizzle was tiny, and Border Collies are usually medium-sized herding dogs. But as the days went by, she started seeing exactly what Sarah meant.

Miss Frizzle’s way of crouching low during play, the laser focus in her eyes, and her seemingly endless energy all started to hint that she might not be a pure Chihuahua after all.
Curious, Susan decided to take another look at the adoption chart from the shelter.
And there it was, plain as day: Chihuahua / Border Collie Mix. She had totally overlooked it in all the excitement of bringing her home, but now it all made sense.

It didn’t take long before Miss Frizzle’s quirky personality and unique breed mix started winning over hearts far beyond just Susan and Sarah.
Amused by the whole mix-up and totally charmed by Miss Frizzle’s playful antics, Sarah decided to share her with the world on TikTok.
In her very first video, she asked, “How can you tell she’s a Border Collie?” as the little black-and-white pup timidly came up to the camera.

The video blew up, and Miss Frizzle instantly became a sensation. Dog lovers all over TikTok jumped in with their thoughts on Miss Frizzle’s breed.
Some spotted the Border Collie traits right away: the black-and-white coloring, her body language, even that classic herding crouch. Others joked that she was some completely different animal.
As Sarah kept posting clips of Miss Frizzle zooming through the house, snuggling on the couch, and showing off her playful antics, her fanbase just kept growing. People couldn’t get enough of her.

No matter if she’s part Chihuahua, part Border Collie, or a mix of something else entirely, one thing is for sure: Miss Frizzle is totally one-of-a-kind.
She may have begun as a shelter pup with a mysterious breed, but now she’s a cherished family member and a viral star all at once.
