When Susan first saw a photo of a small dog online, something just clicked. The pup’s sweet face and tiny frame instantly captured her heart.

Without a second thought, Susan made the drive to a California shelter and brought the dog home, believing she had adopted a Chihuahua.

At first, everything seemed to line up.

The dog was small, quiet, and affectionate. Susan named her Miss Frizzle and settled into a new life with her adorable companion. But soon after, her roommate Sarah noticed something a little off.

Something Didn’t Add Up

Sarah had grown up around dogs and couldn’t help but wonder if Miss Frizzle was more than just a Chihuahua. The dog had a surprising amount of energy and moved with a grace that reminded Sarah of another breed entirely.

Curious, Susan decided to revisit the shelter’s paperwork. That’s when she noticed something she had missed the first time.

Her new best friend wasn’t just a Chihuahua. She was a mix between a Chihuahua and a Border Collie.

The Truth Starts to Show

As the weeks passed, Miss Frizzle’s Border Collie traits became more obvious. She had an athletic, springy way of jumping and a playful, focused energy that never seemed to fade.

When she played, she even dropped into that low, alert crouch that Border Collies are famous for.

Sarah couldn’t resist sharing Miss Frizzle’s story on TikTok. In her video, she playfully joked about how anyone could miss the clear signs that this pup was part Border Collie. Viewers were instantly hooked. The clip went viral, and people from all over chimed in with their own guesses and jokes.

One comment read, “Hey, sorry, that is actually a Chinchilla. Hope this helps!” Others shared their own stories of adopting dogs who turned out to be something completely unexpected.

A Forever Home Full of Love

Miss Frizzle quickly became a fan favorite online. Sarah continued posting short videos of her, showing off the pup’s charming personality and sweet moments at home.

Though Susan was the one who adopted Miss Frizzle, the little dog also formed a strong bond with Sarah. Every morning, as Susan left for work, Miss Frizzle would trot over to Sarah and snuggle close, looking for affection.

No matter what breed mix she is, Miss Frizzle has proven one thing beyond doubt. She’s the kind of dog who brings joy wherever she goes.
