Inside Argentina’s Therian Movement: Why Teens Are Identifying as Animals

The Argentina animal identity trend is taking over TikTok feeds and public parks alike. Young people, known as therians, are gathering in cities across Argentina dressed in animal costumes, behaving like their chosen animal, and building tight-knit communities around this identity. 

The trend has moved well beyond social media and is now drawing responses from psychologists, parents, and policymakers worldwide. Here is everything you need to know.

What Is the Argentina Animal Identity Trend?

The Argentina animal identity trend refers to the growing "therian" movement, where young people identify mentally, spiritually, or psychologically with non-human animals. This is not cosplay for many participants. It is a deeply felt sense of self. 

One Argentine teenager, who goes by Aguara, reportedly told the Associated Press that she identifies as a Belgian Malinois and even counts her age in dog years.

How Big Has This Trend Become on Social Media?

The hashtag #therian has surpassed 2 million posts on TikTok, with Argentina leading all other Latin American countries in engagement.The surge has drawn attention from influencers and mainstream media, triggering reactions ranging from curiosity to outrage. The scale of this youth animal trend online has made it impossible for institutions to ignore.

Where Are These Gatherings Taking Place?

Argentine teens have been gathering in Buenos Aires parks to dress and act like non-human animals. Participants arrive in animal masks and gear, moving and communicating in ways that mimic their chosen animal identity. These meetups have become a recurring feature of the city's youth culture.

Why Has the Argentina Therian Trend Taken Off?

The Argentina therian trend took off, as participant Aguara reportedly told the Associated Press, because of the country's "fairly free" environment. For many young Argentines, the movement has provided a vital community where they feel truly accepted. Social isolation, a desire for belonging, and the reach of global internet culture are all contributing factors.

What Do Psychologists Say About the Argentina Youth Animal Trend?

Debora Pedace, director of the Integral Therapeutic Center in Buenos Aires, reportedly said the youth animal trend reflects symbolic identification, becoming a clinical concern only when it leads to self-harm or harm to others.

The youth animal trend has prompted mental health professionals across Argentina to study its long-term implications more closely.

Is the Therian Identity a Mental Health Concern?

Experts are cautious about pathologising the trend outright. Most draw a clear distinction between symbolic identification, which is largely harmless, and complete behavioural adoption, which warrants clinical attention. The lack of clinical consensus means schools and families are navigating this without formal guidance.

Is the Argentina Therian Trend a Cause for Parental Concern?

Most mental health professionals advise observation over alarm. If a teenager functions normally in school and social life, it is unlikely to signal a deeper disorder. Concern is warranted only when the behaviour becomes all-consuming or affects a child's wellbeing.

What Does This Trend Reveal About Global Youth Culture?

The Argentina animal identity trend is part of a broader conversation about identity fluidity among Gen Z. It reflects how young people are using digital platforms and subcultures to explore selfhood outside conventional categories.
