The dingo (Canis lupus dingo) breeds freely with other domestic dogs. This is now so widespread that in some areas, dingoes are now mostly mixed-breed dogs, crossed in recent times with dogs from other parts of the world. However, DNA study shows that "the dingo originates from domesticated dogs, originally from East Asia" (which reverted to the wild) and so interbreeding between dingos and other domestic dogs is also not a hybridization in the same sense as an interbreeding between different species of Canidae.
Some dingo hybrids have been deliberately bred as pets but turned loose due to behavioral problems. These cross-breeds are accepted back into the wild dingo population, where they breed with pure dingoes. In some parts of Australia, up to 80% of dingoes are part domestic dog. Dingoes are distinguishable from domestic dogs through DNA and through having longer teeth and longer muzzles.
The Australian kelpie sheepdog is widely believed to be the result of crossing dingos with English herding dogs, but this (the dingo blood) is not upheld by breed documentation. The Australian cattle dog breed is known to have been influenced by the dingo.
According to the partwork "Animal Life and the World of Nature" (Vol 1, 1902 – 1903), Lord Walter Rothschild owned a dingo–wolf cross, bred by Mr. and Mrs. HC Brooke from a tame male dingo and a semi-tame female wolf.
In the United States, there is a variety of dingo known as a Carolina dog. Brought over by native peoples migrating from Asia, it is almost identical to the Australian dingo. While once very common in the American south, it was collected and bred for herding. Now possibly extinct in the wild, thousands remain in captivity, some of them crossed with dogs of other breeds to experiment with making them smaller.
