Dogxim, or Graxorra in Portuguese, was a female canid hybrid between a Pampas fox and a domesticated dog that was discovered in Brazil in 2021.
The canid showed a mixture of fox and dog behaviors, and a team of geneticists led by Thales Renato Ochotorena de Freitas and Rafael Kretschmer announced in 2023 that she was a distinct hybrid genetically that “represents the first documented case of hybridization between these two [fox and dog] species”.
She was popularized as the first “fox”-dog hybrid documented in the world, although the Pampas fox and other South American foxes are not true foxes, being instead closer genetically to wolf-like canids, which include dogs.
I didn’t know this was possible. That’s crazy.
