Owners Decide To Adopt Rescue Puppy They Think Is a Labrador-Then She Grows

A couple adopting a rescue puppy made their decision based on looks, believing the dog resembled a Labrador, but as their new pet grew, she looked less and less like the breed they expected.

The owners shared the dog’s original animal shelter listing in a June 5 Instagram post on the account @buffy.the.egg.slayer, along with a quote on the screen reflecting their immediate reaction to her puppy photo. Enthralled by her appearance, they decided to adopt the pup, named Buffy, after thinking she resembled a Labrador with a short, light brown coat. But as Buffy grew, her appearance began to change.

Her once floppy ears evolved, with photos showing at least one consistently standing upright, an unexpected trait for the breed she was initially thought to resemble. Her pink nose also stood out as another surprising feature. While nose pigmentation can vary in dogs depending on genetics, Labrador retrievers are typically described in the United Kennel Club’s breed standards as having black or brown noses.

The caption reads: “Safe to say she wasn’t a Lab…”

Now, fully grown, Buffy’s owners have realized she is far from the popular dog breed they once expected. Looking back, however, the shelter listing itself may have offered an early clue.

Alongside Buffy’s picture, the shelter listed her breed as “mongrel,” a broad term often used for dogs of mixed or unknown ancestry. With limited information provided in the listing, the owners likely formed their initial impression based solely on her appearance.

Despite the unexpected transformation, Buffy’s owners made it clear they have no regrets about bringing her home. The text on the clip reads: “Wouldn’t change a thing.”

Why Shelter Puppies Can Be Difficult to Identify

Determining a puppy’s breed based on appearance alone can be challenging, as physical characteristics such as coat texture, ear shape, body structure and size can change significantly during a canine’s first year of life, according to the American Kennel Club.

Plus, many breed-specific traits do not fully emerge until adolescence or adulthood, making it difficult for shelter staff, veterinarians or potential adopters to confidently label a puppy’s breed.

Research suggests that visual breed identification is often unreliable, particularly in shelter environments where genetic backgrounds are often unknown. A 2018 study published in PLOS ONE examining more than 900 shelter dogs in Arizona and California found that many animals had complex, mixed ancestry that did not align neatly with a single identifiable breed.

The researchers compared visual breed assessments made by shelter staff with genetic testing results and found frequent discrepancies. While staff were sometimes able to correctly identify portions of a dog's ancestry, accuracy decreased significantly when multiple breeds were involved. In many cases, visual assessments only partially matched a dog's genetic results or did not match them at all.

The study concluded that shelter dogs often have diverse and overlapping breed heritage, making visual identification alone an imperfect method for determining breed composition. As a result, the authors noted that breed labeling based on appearance should be treated as an estimate rather than a definitive classification, particularly for mixed-breed dogs like Buffy.
