Mandatory microchip for pets in Spain: what breeders, shelters and veterinarians must do

Key data

If you have a veterinary clinic, a shelter, a breeding operation or simply own a dog, cat, ferret or bird, this regulation affects you directly. The Royal Decree 986/2026 is not a recommendation: it is a legal obligation with a sanctioning regime.

The regulation develops article 51 of the Law 7/2023 on animal welfare and also responds to Regulation (EU) 2026/1818 on the traceability of dogs and cats, bringing Spain into line with European standards. It also includes animals that Law 7/2023 had left out—hunting, rescue and security dogs—by mandate of the Law 8/2003 on animal health.

What does this regulation establish?

Royal Decree 986/2026 establishes a single and homogeneous system throughout the national territory for identifying companion animals. Until now, identification was regulated in a fragmented manner by autonomous communities. This regulation unifies the model.

The mandatory identification methods by species are:

Furthermore, the regulation expressly incorporates hunting, rescue and security dogs, which were excluded from the scope of Law 7/2023 but must now be identified by mandate of Law 8/2003 on animal health.

The identifying veterinarian assumes a central role: they have specific obligations both in the act of identification (placement of the microchip or ring) and in subsequent registration in SICERPA. It is not enough to implant the chip: it must be registered correctly.

Economic and operational impact

The regulation does not set specific fees or amounts in the published text. The economic impact translates into operational and compliance costs for the different actors:

• Veterinary clinics: Need to review their identification and registration protocols in SICERPA. The identifying veterinarian assumes direct responsibility, which implies staff training and updating of internal procedures.
• Breeders: Must ensure that all animals they commercialize are identified and registered before delivery. This may involve an additional cost per animal and a change in sales timelines.
• Shelters: All animals in their care or transferred for adoption must be identified. Shelters with larger volumes of animals will need to strengthen their coordination with collaborating veterinarians.
• Private owners: The obligation to identify also falls on them. Non-compliance is subject to the current sanctioning regime of Law 7/2023 and Law 8/2003.

The real economic risk is not in the cost of the microchip, but in the penalties for non-compliance. Law 7/2023 establishes a sanctioning regime that can reach significant amounts, especially for professional activities such as breeders or clinics.

Who does it affect?

• Pet owners (dogs, cats, ferrets, birds): obligation to identify and register.
• Professional and private breeders: must deliver animals already identified and registered in SICERPA.
• Shelters and animal refuges: all animals under their care must comply with identification before any transfer or adoption.
• Clinics and veterinarians: the identifying veterinarian assumes specific obligations for action and registration. They are the key link in the system.
• Owners of hunting, rescue and security dogs: expressly included by Law 8/2003, although they were excluded from Law 7/2023.
• Regional administrations: must adapt their records and systems to SICERPA as a unified national platform.

Practical example

A golden retriever breeder in Castilla y León sells a litter of six puppies. Before delivering each puppy to the new owner, they are obligated to:

1. Take each puppy to an identifying veterinarian for microchip implantation.
2. Ensure that the veterinarian registers the microchip in SICERPA with the puppy's data and the initial owner's data (the breeder).
3. Transfer ownership in SICERPA to the new owner at the time of sale.

If the breeder delivers the puppies without a microchip or without registration in SICERPA, they incur an infraction subject to the sanctioning regime of Law 7/2023 and Law 8/2003. The same applies to a shelter that transfers a cat for adoption without having previously identified it.

What should companies do now?

1. Identify if your activity is affected: Breeders, shelters, veterinary clinics and owners of hunting, rescue or security dogs have specific obligations. Do not wait for an inspection.
2. Review the identification protocol and registration in SICERPA: The identifying veterinarian must correctly register each animal. Clinics must update their internal procedures and train responsible staff.
3. Update contracts and documentation for sale or transfer: Breeders and shelters must prove that the animal is identified and registered before delivery. Include this requirement in your transfer or sales documents.
4. Verify the status of animals already in your possession: If you have animals that are not yet identified or not registered in SICERPA, remedy the situation as soon as possible to avoid penalties.
5. Consult with a veterinarian or legal advisor if you have doubts about the specific registration procedure or about the specific obligations according to your type of activity.
