Animal Welfare and Traceability for Dogs and Cats: What Breeders and Sellers Must Do in 2026

Key data

Professional breeders, pet shops, shelters and online sales platforms have new obligations under the Regulation (EU) 2026/1818, published on 10 August 2026. The regulation harmonises animal welfare standards at European level and creates a mandatory traceability system that allows tracking the origin and movements of each animal. The stated objective is to combat illegal trade and intensive breeding farms.

Spain, like other Member States, must adapt its national legislation to transpose the regulation's requirements within the established timeframes. This involves operational and administrative changes for all actors in the chain: from the breeder to the digital platform that publishes the sales advertisement.

What does this regulation establish?

Regulation (EU) 2026/1818 introduces a harmonised framework with three main pillars:

The regulation is a European regulation of direct application, which means it does not need to be "transposed" article by article like a directive, but it does require Spain to adapt its national legislation to eliminate contradictions and cover the development aspects that the regulation delegates to Member States.

The traceability system is specifically designed to tackle illegal trade and intensive breeding farms, two issues that the European Commission has identified as priorities in its animal welfare strategy.

Economic and operational impact

The impact is not just regulatory: it involves real adaptation costs for companies and professionals in the sector. The main cost vectors are:

• Animal registration and identification: Each dog or cat must be linked to an official traceability system, which may require investment in microchips, documentation and management software.
• Facility adaptation: Professional breeders must comply with new minimum care requirements and breeding conditions, which may involve construction work or changes in daily management.
• Obligations for online platforms: Animal sales platforms must verify and publish traceability information in each advertisement, which involves technological and process changes.
• Penalty risk: The regulation provides for significant penalties for non-compliance. The exact amount of penalties is not specified in the published text and will depend on the regulatory development of each Member State.

The regulation does not set specific penalty amounts in the available text, but it does establish that violations "may result in significant penalties". The specification of those penalties in Spain will be in the hands of the national legislator during the adaptation phase.

Who does it affect?

• Professional breeders of dogs and cats: required to comply with new animal welfare standards and integrate into the traceability system.
• Pet shops that sell dogs or cats: must prove the traceable origin of each animal they sell.
• Shelters and animal protection organisations: fall within the scope of application and must adapt to new registers.
• Online sales platforms that publish advertisements for dogs and cats: required to verify and display traceability information.
• Owners of dogs and cats in the EU: affected in that animals they acquire must have traceability documentation.
• Spain as a Member State: must adapt its national legislation to transpose the regulation's requirements within the established timeframes.

Practical example

Imagine a professional golden retriever breeder based in Valencia who sells between 30 and 50 puppies per year through its own website and a pet online platform.

With Regulation (EU) 2026/1818 in force, this breeder must:

1. Register in the official register that Spain establishes as development of the regulation.
2. Ensure that each puppy is identified and linked to the European traceability system before being delivered to the buyer.
3. Prove that its facilities comply with the minimum animal welfare requirements established by the regulation.
4. Provide the online platform where it advertises the puppies with the required traceability data so the advertisement can be legally published.

If it fails to meet any of these requirements, it is exposed to the penalties that Spain sets when transposing the regulation, which the European text describes as "significant".

What should companies do now?

1. Identify if your activity falls within the scope of application: Breeders, pet shops, shelters and online sales platforms for dogs and cats are directly obligated.
2. Review the animal identification and documentation system: Check if your current microchipping and documentation process is compatible with an interoperable traceability system at European level.
3. Audit breeding and housing conditions: Compare your facilities with the minimum animal welfare requirements established by the regulation to anticipate possible adaptations.
4. Follow regulatory development in Spain: The Government must publish the adaptation legislation with the specific timeframes and penalty regime. Stay informed so you don't miss deadlines.
5. If you operate an online platform: Begin technical analysis now to incorporate mandatory traceability fields in animal sales advertisements.
6. Consult with a specialist advisor: Since the penalty regime will be set by Spain, it is advisable to seek legal advice to anticipate the level of risk.
