Wolfdog
The wolfdog is the product of a wolf and a domestic dog cross. They look as adorable as the usual dogs but their behaviors are much more unpredictable. Currently, in the United States alone, there are 300,000 to 500,000 wolfdogs, which is a considerably large population of hybrids.
To get a thicker, fluffier coat on these hybrids, they are often crossed with Siberian Huskies or Alaskan Malamutes. Unlike most other hybrids like ligers, these hybrids are not infertile, therefore they can reproduce among themselves as well.
