Pigs are smart! Their intelligence is higher than a dog's, some primates and even young human children³.
In their natural state, pigs are very clean animals. They keep their toilets far from their living or feeding areas.
They are much more tolerant of colder temperatures than heat. Pigs have no sweat glands so they can't sweat. This is why they enjoy being in mud to keep themselves cool.
When they are trained piglets can learn their names at just two to three weeks old. They can learn to respond when called and learn tricks faster than dogs.
Pigs use grunts to communicate with each other. The grunts made by pigs vary depending on the pig's personality and can convey important information about the welfare of this highly social species¹.
Pigs have excellent memories. They can remember things for years and can recognize and remember objects!
Newborn piglets learn to respond to their mothers’ voices, and mother pigs communicate with their babies through grunts while nursing. Scientific research has found that piglets have a certain teat order and each piglet has its own teat to suckle from.
Pigs like to get massages, enjoy scratching themselves on trees, relaxing while listening to music, and playing with enrichment toys.
The highest density of tactile receptors is found in the pig’s snout. Pigs use it mainly to dig in the dirt and smell food. A pig’s sense of smell is about 2000 times more sensitive than human's.
Pigs are incredibly social. They form close bonds with each other and other animals. To keep warm, pigs may cuddle up with one another.
