What is the microchip for pets?


When you decide to live with a dog or cat, one of the first things to do is take it to the veterinarian to implant the microchip so that it can be easier for us to find it in case it gets lost.

With a simple gesture, which will not cause any damage to the animal (it will feel what we can notice when a mosquito bites us), we can have it more controlled. If you want to know how are dog and cat microchips, keep reading 🙂.

What is the microchip?

The microchip is a electronic system used to identify animals. It is formed by what is the microchip itself, and a soft and biocompatible glass capsule (does not cause allergies) that covers it. Its size is very small, like a grain of rice, so it will barely be noticed once it is implanted.

Each of them stores a unique number code, which would be its own ID.

Who and when do you have to wear it?

More or less when the animal is two months old, a veterinarian will implant the capsule in the animal's neck (normally, on the left side) by means of an injector that, by means of a plunger, pushes it once the skin is pierced.

Then, what the professional will do will be record the information related to the dog or cat in the database of the Census of Pets of each Autonomous Community, in which the information related to each chip is stored, such as the name of the caregiver, address and contact numbers.

In the event that the animal dies or changes its address, the veterinarian must be notified to make the relevant changes.

Is it mandatory to put the microchip to pets?

In the specific case of dogs, yes. In the case of cats it is only in Andalusia, Cantabria, Madrid, Catalonia and Galicia. Even so, it is very important to put it on, regardless of which animal it is, since It serves to avoid abandonment, to find it in case of loss and to prove that we are the owners.

And you, have you already put the microchip on your friend?

The content of the law

In Spain, the law requires the identification of companion animals, including cats that do not leave the house, in the case of abandonment, loss,Stole, etc. In some communities the animal is identified by tattoo or chip, but more and more are the ones that force the electronic system to be implanted.

What is the microchip for?

Implement the chip to our pets It can be beneficial for several reasons:

  • For the purposes of the law we can confirm without any problem that we are the owner of our pet. It is impossible to falsify the data of the microchip.
  • In case of loss of animal, both veterinarians and protectors and authorities (SEPRONA), through a reader, can access our data.
  • The ID by chip It helps to avoid abandonment, since the law punishes people who leave or mistreat a person with fairly high penalties. animal. In this way, you can prove who is the owner and legal responsible of a animal abused or abandoned.

What to do in case of loss or theft of my pet?

The fastest> taken out, leaving the animal without identify. Therefore, the option of microchip It is the most reliable.

If our pet It has been lost or stolen, it is important that we notify you immediately:

  • To the Local Police.
  • To SEPRONA (Nature Guard Service of the Civil Guard).
  • To the City Hall.
  • To the REIAC (Spanish Network of Identification of Pets).
  • To the center where we adopt the animal (in case it was adopted).

In our writing we have to indicate the number of chip and the name of animal, our personal data and, if we know it, the date and place where it was lost or stolen from our pet.

Also, if a person finds a animal lost, you should go to any veterinarian, who will read the ID of the animal and try to locate the owner.

What does the law say?

In Spain, the law requires identify to the animals of company, even at cats They don't leave home. In some communities it identifies to the animal by tattoo or chip, but more and more are those that force to implant the electronic system.

If we have a dog or a cat It is mandatory to register it in the City Council presenting:

  • A copy of the veterinary card or passport of the animal.
  • A copy of our ID.
  • A copy of the document registered in the Company Animal Identification File.

We will also have to fill in the census form and pay the established fees.

In case of death, we must cancel it in the census.

Each Autonomous Community has its regulations, but as we have pointed out previously, more and more are the ones that force the implementation of the chip. For example, in Andalusia, the Law 11/2003, of November 24, on the Protection of Animals He says:


Article 17. Identification.

1. Dogs and cats, as well as other animals that are determined by regulation, must be />

2. The identification will be reflected in all documents and files in which the animal is recorded and will be an essential requirement for registration of the animal.

Article 18Municipal Register of Pets.

Owners of dogs and cats, as well as other animals that are determined by regulation, must register them in the Municipal Register of Pets of the City Council whereThe animal usually lives, within a maximum period of three months from the date of its birth or within a month after its acquisition or change of residence. Likewise, they must request the cancellation of the inscriptions made within a maximum period of one month from the date of their death, loss or transmission.

Article 19Central Register of Pets.

1. The Central Register of Pets is created, under the Ministry of the Interior, which will be constituted by the set of inscriptions of the respective municipal registries. The organization and operation of this Registry shall be determined by regulation.

2. The City Councils must communicate periodically, and in any case at least semiannually, the ups and downs that occur in the Municipal Registry, as well as changes in the census data.

3. The Administration of the Junta de Andalucía and the Town Halls within the scope of their competences, without prejudice to their responsibility in the field of pet animal censuses, may conclude agreements with the official veterinary associations for the conduct and maintenance of censuses and records.

The continental Europetnet network

Europetnet is a group of national and local associations across Europe that share the identification records of all companion animals that have the microchip implanted

If we travel abroad with our dog and we have the bad luck of misleading it, just enter the identification number of the animal on the Europetnet website and we will obtain the registration of the entities through which our pet since the day it was lost.

On the other hand, in case of finding a stray animal it is advisable to take it to a veterinarian or protector and enter the number of the chip in the web. In this way, we can contact the association that appears related to the animal.

The countries that are part of Europetnet are: Germany, Austria, Belgium, Cyprus, Slovakia, Spain, Estonia, Denmark, Holland, Hungary, Ireland, Lithuania, Luxembourg, Norway, Poland, United Kingdom, Czech Republic, Russia, Sweden and Switzerland.

In Spain, the main agency responsible for all this is the REIAC (Spanish Network for the Identification of Pets). The REIAC groups the databases of the animals with microchip and offers a centralized system for consultation and location. It includes a real-time online consultation system with those veterinary associations that implement a new consultation protocol and automatically sends the data to the Europetnet network.

I would like to know or if someone could inform me of:
1- My Chihuahua dog has not done the year yet, but the microchip has moved from the nape or base of the ear until almost past the pallet joint of the front leg. It is normal? Because it seems to bother you by not stop scratching every moment.
2- Can or should the number of the microchip be tattooed on the ear?
What should I do?
Thank you.

I taking advantage of this topic, and a conversation I had the other day, with a friend! I wanted to ask you a question, my friend tells me, that when he got one of his dogs, they put a chip of last generation, which belonged to a state archive, and then it was registered in a European archive! So in case of lost, it would be easier to find your pet, now recently acquired another dog, and when putting the chip, they put a simpler one! That he could only locate the dog at the state level, and by saying that he wanted the double registration, as in his first dog! They told him that he had to pay 40 euros more, apart from the chip, so that it would appear in the European archive, what makes me think, what a panda of quacks, are veterinarians! How can this be possible? Does anyone know why? The first dog had double registration on the chip, and why do you now have to pay? Is anyone aware of this? Greetings.

What exactly is the microchip?

The identification microchip is a Electronic device about the size of a grain of rice, which is implanted under the skin of the animal by a veterinarian. It has a code of 15 numbers and allows the individualization of the animal and relate it to its responsible human. Its duration is more than 20 years. Contrary to what many people think, the chip has no GPS. It is the only permanent identification system and it is an obligation that your dog and / or cat has it, regardless of whether or not it is of breed.

In Chile the device must comply with international standard ISO 11784, in this way the information can be read all over the world. This rule applies to all countries that have implemented this system, so you can also control the entry and exit of pets: in the countries of the European Union, for example, it is mandatory that the pet is identified with a microchip at the time of enter

Is it safe for my pet?

Yes. The microchip is used worldwide and its implantation does not report animal health risks. When going under the pet's skin, it can be uncomfortable at the time of applying it and some animals can be stressed by the procedure, but in no case will you feel pain.

Where can I get the microchip?

The chip can be obtained in veterinary clinics, whether public or private. The important thing is that you have the 15 digits That are required. We recommend you first ask for information in your municipality, as there are some that offer the service for free. Also there you can get a list of the veterinary centers of the commune where you can get the chip.

How do I register my pet?

The first step To register your pet in the National Registry is the implantation of the microchip. This can be done from two months of age of the animal.

The second step It is to prove that you are the owner of the pet. You can do this with documents such as the purchase ticket or a simple affidavit, which you can download from the website, and in which you must identify your dog or cat with the following information: name, microchip number, species, sex, color , age (actual or estimated), reproductive status and race, if applicable.
