The interbreeding of dingoes with other domestic dogs is an ongoing process affecting the population of free ranging domestic dogs in Australia. The current population of free ranging domestic dogs in Australia is now probably higher than in the past. However, the proportion of the so-called "pure"[1] dingoes (dogs with exclusively dingo-ancestry) has been in the decrease over the last few decades and is regarded as further decreasing. Because of this ongoing interbreeding of dingoes and other domestic dogs and the resulting hybrids, there is a much wider range of colours and body shapes today among the Australian wild dog population than in the time before the European colonization. The full extent of the impacts of this process is currently unknown and the possibility of potential problems, as well as the wish to preserve the "pure" dingo, often leads to a strong rejection of the interbreeding.
