what does a Water Hog look like? (The Pet)?

Answer 1

Because hogs like to wallow in mud, people sometimes think of them as dirty animals. When given a choice hogs stay in clean water, rather than in mud. Lying in water helps hogs cool off on a hot day. The animals have few sweat glands in their skin so they cannot cool off by sweating. They can be found in water frequently to keep their body temperature low and to escape insects.
