Do I have to microchip and register my dog or cat?
Yes — in Lithuania dogs, cats and ferrets must be marked with a subcutaneous microchip and entered in the Pet Register; this is mandatory, not the owner's choice. The popular myth that only dogs must be registered is misleading — the requirement applies equally to cats and ferrets. The Pet Register has operated since 1 January 2016, it is run by the state Agricultural Data Centre, and it is supervised by the State Food and Veterinary Service. Once an animal is chipped, it must be registered within 7 days, and a newly acquired pet must be chipped within the set period but no later than before it is handed to another owner. The key point people miss: it is prohibited to sell or give away an unmarked and unregistered dog, cat or ferret, so the breeder and the seller are also responsible for compliance. The microchip helps find the owner if the animal runs off and proves who it belongs to.
📋 The rules

- Oversight rests with the State Food and Veterinary Service (VMVT)

- Travelling in the EU with a pet also needs a pet passport and a rabies vaccination
⚠️ Penalties & fines
An unmarked and unregistered pet is an administrative offence, not a trifle. Under Article 346 of the Code of Administrative Offences, breaching the animal-welfare, marking and registration requirements brings a fine of 30 to 120 €; if the breach causes harm to a person's health or property, 150 to 300 €, and on repeat 300 to 550 €. What owners miss: for a breach the animal can be confiscated, and a stray unregistered pet often cannot be returned because there is no way to identify the owner. When selling or giving away an unmarked animal, the transferor is liable, and stricter requirements apply to breeders. Without registration a pet passport is not issued either, so such an animal cannot legally travel to other EU states.

❓ Frequently asked
Must I register a cat, or only a dog?
You must microchip and register not only dogs but also cats and ferrets, so the widespread belief that this applies to dogs alone is mistaken. Pets of all three species have to be entered in the Pet Register, and the same rules on marking and deadlines apply to each.
How much does chipping and registering a pet cost?
The microchip is implanted by a vet and it is a paid service whose price depends on the clinic. Registration in the Pet Register is usually done during the chipping, and it is worth checking the exact price at your chosen veterinary clinic.
How long do I have to register the animal?
A chipped pet must be entered in the Pet Register within 7 days of the marking. A newly acquired animal must be chipped within the set period, but in any case no later than before it is transferred to a new owner.
What happens if my pet is not chipped?
Breaching the marking and registration requirements brings a fine of 30 to 120 euros under Article 346, rising to up to 550 euros on repeat. On top of that, the animal can be confiscated, and a stray unregistered pet often cannot be returned to its owner.
Do I have to re-register the pet if the owner changes?
Yes, if the pet's owner or contact details change, the register data must be updated so that the microchip actually points to the current keeper. If the data is not updated, a lost animal may be returned to the wrong person or not returned at all.
