Foxes sure look like a mix of both dogs and cats. Does that mean that a fox is a type of dog?
The short answer is no, but they are genetically related.
Foxes are not dogs nor cats—they are their own species. However, foxes are related to dogs, wolves, and coyotes - all of which are members of the Canidae family.
Biologically speaking, foxes share some genetic code with dogs. Still, since their genes diverged from dogs around seven to ten million years ago, they are very different animals.
Foxes and dogs have an incompatible number of chromosomes. Dogs have 78 chromosomes, while red foxes only have 38.
In simple words:
The genetic makeup of foxes is too different from that of dogs, and therefore, they cannot interbreed together.
Foxes may look more like dogs, but they actually share more behavioral and physical traits with cats.
Foxes are not dogs and cannot interbreed with them. They actually have more in common with cats than with dogs.
