Tick-borne dog infectious diseases constitute an emerging problem in veterinary medicine in recent years. The diseases recognized as characteristic for tropical and semi-tropical regions are diagnosed in dogs in countries with temperate climate including Poland. The major reason for such phenomenon is that Polish tourists increasingly travel with their dogs into subtropical and tropical areas of the world.

Tick-borne diseases can result from infection with bacteria, viruses and parasitic protozoa. In this review we present most important tick-transmitted diseases which may occur in dogs in Poland.
