About PetBase

PetBase was established in 1998 under the name DAISYWeb as first online pet animal database. Today, we are one of the largest pet animal databases in the Netherlands.

At PetBase, microchipped dogs, cats and other pets can be registered, so they can be reunited with their owners after they have gone missing. The animal clinic, animal shelter or breeder can do the microchipping and registration for you, ensuring a correct procedure.

Since April 1st 2013, it is required by law to microchip and register dogs. PetBase is a government-approved database for registering microchipped dogs. For more information on the compulsory identification and registration for dogs (I&R) read more here.

Welcome to PetBase

PetBase is a government-approved database for registering microchipped dogs and other pets. Because it has been microchipped, we can reunite you and your pet once it has been found. Your vet, animal shelter or breeder can take care of the registration for you. Make sure your information is correct and do not forget to update in case of any changes, such as moving house.

“Animals are reliable, give lots of love, are faithful to their owners, predictable in their behaviour, thankful and loyal. Qualities which we humans can learn from.”
