In 2010, Millan’s life hit rock bottom. Reeling from the death of his beloved pit bull, Daddy, and a bitter divorce from his wife, Ilusión, Millan attempted to take his own life.

The backlash was so severe that it led to an official investigation. Though he wasn’t charged, the incident left a stain on his reputation. For many, it was a shocking moment that turned admiration into skepticism.

Before Cesar Millan became a household name, he crossed the U.S.-Mexico border illegally at just 21 years old. With no money, no English skills, and no connections, Millan spent his early days living in poverty, walking dogs to survive. His journey to fame was anything but glamorous, and the fear of deportation loomed over him constantly. While his story is one of perseverance, it’s also a reminder of the struggles undocumented immigrants face. Millan’s rise to the top is inspiring, but his early hardships were anything but enviable.
5. The Alpha Philosophy That Divides Experts

Millan’s “alpha” philosophy may be iconic, but it’s also highly divisive. While he insists that dogs need a pack leader, critics say his methods are based on outdated ideas about dominance. Modern animal behaviorists argue that fear-based training can harm dogs, making them anxious and unpredictable. Some even claim his techniques are borderline abusive. For every fan who swears by his methods, there’s an expert who condemns them. This divide has sparked heated debates in the dog training world, leaving Millan at the center of ongoing controversy.

Videos of Millan pinning dogs to the ground or using aggressive corrections have gone viral, igniting debates about whether his training style belongs in the modern world. While his defenders argue that his methods work, the backlash paints a darker picture of a man who many believe prioritizes results over compassion.

Behind the scenes of his rise to fame, Millan’s personal life was falling apart. His wife of 16 years, Ilusión Millan, filed for divorce in 2010, citing irreconcilable differences. The separation was not only emotionally devastating but also financially crippling. Millan was ordered to pay a massive divorce settlement and ongoing spousal support, leaving him in financial turmoil. For a man who seemed to have it all, the divorce exposed the cracks in his seemingly perfect life, adding another layer of tragedy to his story.

Millan’s pit bull, Daddy, was more than just a pet—he was the heart of Millan’s work and his constant companion. When Daddy passed away in 2010, Millan was devastated. The loss marked the beginning of one of the darkest periods in his life, as he struggled to cope with the death of his best friend. Fans who followed their bond on-screen were heartbroken, but for Millan, it was deeply personal. Daddy’s death left a void that even his work with other dogs couldn’t fill.
9. Financial Struggles That Almost Broke Him

Before his big break, Millan’s life was anything but glamorous. He spent years living in poverty, walking dogs and grooming pets to make ends meet. At one point, he was homeless, sleeping in a kennel and relying on the kindness of strangers. His rise from poverty to fame is inspiring, but it came at a steep cost. The financial struggles he endured early in his career are a stark contrast to the luxurious lifestyle he later achieved, proving that success often comes after immense hardship.
