A walk in the park could cost you thousands if your dog’s ID isn’t up to scratch. While microchipping grabs the headlines, it’s the humble collar tag that’s often forgotten—and it could land you with a £2,000 fine. Here’s what every UK dog owner needs to know to stay on the right side of the law and keep their furry friend safe.
Every dog owner in the UK faces a potential £2,000 fine if their pet doesn’t wear proper identification when out in public. This legal requirement, often overlooked by many pet owners, extends beyond simple microchipping and involves specific collar requirements that every responsible owner must understand.

Legal Requirements for Dog ID Tags in the UK
What the Law Actually Says
Under UK law, all dogs must wear a collar displaying their owner’s name and address when in public spaces. The legislation is clear and applies to dogs of all breeds and sizes that are eight weeks old or older.
Key legal requirements:
- The owner’s name must be clearly visible
- The current address must be displayed
- Information must be legible and durable
- A telephone number is recommended but not mandatory
Understanding the £2,000 Fine
The maximum penalty for non-compliance with dog identification laws can reach £2,000. This substantial fine reflects the importance authorities place on pet identification for public safety and reuniting lost animals with their owners.
Microchipping vs Collar Tags: Both Are Required
The Dual Requirement System
Many pet owners mistakenly believe that microchipping alone satisfies legal requirements. However, UK law mandates both microchipping and visible collar identification.
Microchipping requirements:
- All dogs must be microchipped by eight weeks of age
- Breeders are responsible for initial registration
- New owners must update registration details within 21 days
- Microchip details must remain current
Collar tag requirements:
- It must be worn whenever the dog is in public
- Information must be immediately visible
- No requirement for specific materials or design
- Must be securely attached to prevent loss
Exemptions to the Rules
The law provides limited exemptions for specific circumstances:
Working dog exemptions:
- Some working dogs may be exempt from collar requirements
- Exemptions apply only in particular working situations
- Normal pet activities require standard compliance
Health exemptions:
- Veterinary certificates can exempt dogs from microchipping
- Health reasons must be documented and verified
- Collar exemptions are extremely rare
