From 1.1.2020 all dogs (except those who are tattooed before 2011) must be microchipped. 
If the dog will not have a chip, vaccination against rabies will not be valid anymore. 

Many dog owners are concerned about chipping. That's why we have made a short video - https://www.youtube.com/watch?v=czBxAieA6zI how chipping works. If done correctly, for most dogs it is a painless and quick procedure.
Before the actual chipping we scan the dog if there is any microchip present. 

Then the application is performed - see video. After the application, we check with the reader again that everything is in order.
 Beware that the owner must register his chip number in the register! E.g. www.narodniregistr.cz or www.backome.cz.
