Do I have to microchip my dog?
Eventually yes: microchipping dogs and cats will become mandatory. In 2026, the act on the National Register of Marked Dogs and Cats (KROPiK) was passed and signed, introducing mandatory electronic marking (microchipping) and registration of dogs and cats. Most rules take effect 3 years after the act's publication, so the duty will be phased in — but some municipalities already require microchipping under local programmes. The chip is implanted by a vet, and the cost of marking and registration is at most about 0.56% of average pay (currently about 50 zł per action). For animals already chipped, just registration suffices, which for 3 years after the rules take effect is to be free. The chip and register make it easier to find the owner of a lost animal.
📋 The rules
- KROPiK act (2026): mandatory chipping and registration
- Most rules take effect 3 years after publication
- Some municipalities require chipping already now
- The chip is implanted by a vet; cost about 50 zł
- Already chipped: just registration, free for 3 years
🔓 Exceptions
- Already-marked animals: just registration in KROPiK
- Local municipal programmes: free chipping in campaigns
- Full duty kicking in: only after a transition period (3 years)
⚠️ Penalties & fines
Once the rules take effect, a missing chip and registration will risk a fine of 20 to 5,000 zł. The register aims to curb homelessness and ease identifying the owner — abandoning or abusing an animal are separate, heavily penalised acts. To prepare for the new duties: consider microchipping your dog or cat now (especially if your municipality requires it), register the animal in the relevant register once KROPiK launches (registration of chipped animals is to be free for 3 years), and keep contact data updated. A chip genuinely raises the chance of recovering a lost pet and is often required for travel abroad.

❓ Frequently asked
Is microchipping a dog mandatory?
Eventually yes. In 2026 the KROPiK act was passed, introducing mandatory microchipping and registration of dogs and cats. Most rules take effect 3 years after publication, so the duty will be phased in. Some municipalities, however, already require chipping.
What is KROPiK?
It's the National Register of Marked Dogs and Cats — a central database recording chipped animals with the owner's data. It's meant to curb animal homelessness and ease finding the owner of a lost dog or cat, thanks to the chip number read by a scanner.
How much do chipping and registration cost?
The maximum cost of each action is about 0.56% of average pay — currently about 50 zł. The chip is implanted by a vet. For animals already chipped, just registration suffices, which for 3 years after the rules take effect is to be free.
What's the fine for no chip?
Once the duty takes effect, a missing marking and registration will risk a fine of 20 to 5,000 zł. The rules aim to fight homelessness and ease identifying the owner. Separately, abandoning and abusing an animal are heavily penalised.
Is it worth chipping a dog now?
Yes. A chip genuinely raises the chance of recovering a lost animal and is often required for travel abroad (alongside an animal passport). Many municipalities offer free chipping in local campaigns. Early chipping will also ease meeting the duty once the KROPiK register launches.
