EU introduces mandatory microchipping and stricter rules for dogs and cats to combat illegal trade

The European Union has adopted sweeping new regulations requiring microchipping for all dogs and cats while imposing uniform standards on breeding and trade, DR reports. The measures aim to dismantle a billion-euro black market plagued by fraud and animal suffering.

The European Parliament approved the comprehensive regulation this week, following an agreement with the EU Council from November 2025. The rules introduce binding requirements for owners, breeders, and sellers across all 27 member states, marking the first EU-wide framework for dog and cat welfare.

“This is a historic step for animal welfare in Europe,” said Jens Jokumsen, head of companion animals at Dyrenes Beskyttelse (Animal Protection Denmark). “For the first time, we have unified standards governing how these animals are bred, kept, and traced across borders—measures that will tangibly improve their lives.”

The regulations target a long-standing lack of oversight that has enabled cross-border trade in animals with inadequate documentation, often under conditions harmful to their well-being. Key provisions include:

• Mandatory microchipping and registration: All dogs and cats must be implanted with microchips and logged in national databases linked across the EU, making anonymous sales far more difficult.
• Minimum welfare standards: Uniform rules now govern space, lighting, temperature, nutrition, and veterinary access for breeding and keeping animals.
• Crackdown on puppy mills: Permanent caging is banned, and new limits restrict the age and frequency at which animals can be bred. Extreme physical traits that cause health issues are also prohibited.
• Stricter sales oversight: To curb traffickers posing as private owners, all advertised animals must be registered, closing loopholes in cross-border trade.

The rules will affect an estimated 72 million dogs and 83 million cats in the EU. While Denmark already mandates dog registration, cats will now face similar requirements—though working farm cats and service dogs (e.g., police, military, or customs units) are exempt.

Enforcement challenges remain

Critics warn that the law’s impact hinges on enforcement. “The worst offenders often operate outside any system—they avoid vets, ignore rules, and stay hidden,” said Maja Olander Henrichsen, a retired pedigree cat breeder and former Dyrenes Beskyttelse leader. “The question is who will police the unregistered breeders.”

Jokumsen acknowledged the hurdle but stressed that mandatory ID-marking and cross-border databases will make it “far harder to trade anonymously.” Authorities will gain tools to track patterns and flag suspicious activity, he added.

The regulations phase in gradually: breeders, sellers, and boarding facilities have up to four years to comply, while private owners face a 10-year deadline for dogs and 15 years for cats. The EU’s goal is clear—to dismantle illegal trade networks while raising welfare standards for millions of pets.
