Who is allowed to set the chip?
It is different from country to country. In some cases every qualified person is allowed to set the chip, in other only the vet. Please get the information from your respective authorities. In the EU every qualified person is allowed to set the chip.
Our recommendation: Please let a vet do the injection if you are not familliar with animal identification! Many vets agree to set the chip you can buy here and bring them with you. So you can spare your pet from suffering but also save some money.
The left neck side, where the chip is supposed to be set, is a very sensitive place wth a lot of blood vessels. So it is importatnt to let an expert do the injection.
