New research from the RSPCA and Inspiring Vet Care highlights a significant shift in how British pet owners choose names. Traditional classics are being replaced by modern, human-like monikers such as Luna and Milo.

Luna’s 31,900 registrations and the decline of the "Fido" era

The dominnance of human-centric names is clearly reflected in recent registration data. According to research from the RSPCA and Inspiring Vet Care, Luna has emerged as the premier female pet name with 31,900 registrations, while Milo leads the male category with 22,300.

This trend marks a sharp departure from the era of traditional animal identifiers. As Petgevity reported in their January data, the once-ubiquitous names Rover and Fido have become rarities, with only four and two registrations respectively recorded in 2025.. Even the name Lassie has dwindled to a single recorded instance across the United Kingdom. this shift is equally visible among feline companions; out of 5,100 cats registered last year, only 11 were named Tabby and just five were called Spot.

While modern names dominate, some classic choices maintain a foothold in the UK. The top lists for both genders still include traditional elements:

  • Top Male Names: Milo, Teddy (20,200 registrations), Alfie, Charlie, Buddy, Max, Oscar, Bailey, Archie, and Monty.
  • Top Female Names: Luna, Bella (30,400 registrations), Poppy, Daisy, Lola, Molly, Rosie, Willow, Ruby, and Coco.

    • The Taylor and Ariana effect on British pet ownership

    Pop culture and digital influence are driving the current naming revolution. Richard Hooker, the country medical director for Inspiring Vet Care, noted that pets are increasingly being named after celebrities, citing a rise in names like Taylor, Ariana, and Sabrina.

    Social media serves as a primary catalyst for these aesthetic choices.. A survey of 2,000 pet owners revealed that nearly two-thirds of respondents identify social media as a major influence on their naming decisions. Furthermore, the influence of entertainment media is widespread, with approximately 25% of owners naming their animals after characters from films and another 25% drawing inspiration from television shows.

    Floral themes also represent a significant sub-trend in the UK. Among the top ten female names, names such as Rosie, Daisy, and Poppy account for one-third of the total, suggesting a preference for nature-inspired, soft-sounding monikers.

    Will the "Lord Volde-tort" trend lead to vet clinic awkwardness?

    The move toward highly specific or character-driven names raises questions about social stigma in professional settings.. While Petgevity warns owners against choosing names they might later find embarrassing, the data shows that only 37% of owners actually consider whether a name might be awkward to call out at a veterinary clinic.

    Several uncertainties remain regarding the longevity and social impact of these trends. It is currently unclear if the rising popularity of names inspired by England footballers—which Richard Hooker says are appearing frequently but have not yet cracked the top ten—will eventually disrupt the current leaders. Additionally,the source does not address the potential for long-term regret when names are chosen by young children, a factor Petgevity suggests can lead to owners "mumbling" names like Lord Volde-tort to avoid embarrassment.

    Finally,while the data highlights owner sentiment, it remains to be seen how these naming shifts affect the professional interactions between veterinary staff and clients, as the line between human and pet identities continues to blur.
