It's most commonly seen in certain animals, like:
* Cattle: Their dewlaps are prominent and often used for identification purposes.
* Dogs: Some breeds, like the Shar-Pei, have dewlaps.
* Goats: Dewlaps are also common in goats, especially in some breeds.
* Lizards: Some lizard species have dewlaps that they use for display and communication.
While humans do not have dewlaps, they sometimes have a loose fold of skin under the chin called a "double chin" due to fat deposits in the neck.
