“Dogs share 99% of their genes with wolves and can have children with each other. However, both are also so closely related to a whole host of other species that it is possible to for them to produce fertile offspring with jackals, coyotes, the Australian dingo, the African wild dog, Arctic foxes, and the Black fox Coren (2013). The species boundary is obviously not a barrier for reproduction. And of course, all types of dogs are able to cross-breed.” — Martin Balluch
