Pigs are more intelligent than dogs.

Pigs are mostly pink and have a bristly fur. But depending on the breed, they can be brown, black or pied. It is said that the animals are dirty, because they like to wallow in mud. In fact, they simply make themselves a cooling mudpack in hot weather, just as elephants do. In addition, the mud protects against insect bites. Some people even keep pigs as pets - because they are very peaceful, sensitive, social, curious and intelligent.
