ELI5: Can animals become feral?

So when humans are raised by other animals (and are removed from human contact), they become "feral" as in they can't properly / have a hard time communicating with other people and generally have a tough time learning a human language.

That being said, can animals become feral? Suppose a puppy is taken from his mother as soon as it's born, or a chinchilla and don't communicate with others of their kind... are they still able to properly communicate with other dogs/chinchillas or do they exhibit traits to humans who are feral.

Pigs revert.  When domesticated pink pigs escape barnyards and get into the woods, their hair grows thick and bristly and they grow tusks.  It doesn't take them generations to do this, the actual pig who escaped gets wild again.
