Pigs were domesticated thousands of years ago. They are farmed for their meat and hides. There are still many wild pigs, like the wild boar, the warthog, and the bushpig. Pigs are found on every continent on Earth except Antarctica.
Names: Pigs are also called hogs or swine. The adult female is called a sow. The adult male is called a boar. A baby is called a piglet.
Anatomy: Pigs vary in color from brown, black, white, to pinkish. Some wild pigs have large tusks, overgrown teeth used for fighting and digging for food.
Diet: Pigs are omnivores . They eat a variety of plants and small animals.
Classification: Class Mammalia, Order Artiodactyla, Family Suidae.
A pig has a snout for a nose, small eyes, and a small tail, which may be curly, kinked, or straight. It has a thick body, short legs, and coarse hair. There are four toes on each foot, with the two large middle toes used for walking.
pigs are omnivores, which means that they consume both plants and animals. Pigs will scavenge and have been known to eat any kind of food, including dead insects, worms, tree bark, rotting carcasses, garbage, and even other pigs. In the wild, they are foraging animals, primarily eating leaves, grasses, roots, fruits and flowers. Occasionally while in captivity, pigs may eat their own young if they become severely stressed. A typical pigs has a large head with a long snout which is strengthened by a special bone called the prenasal bone and by a disk of cartilage in the tip.The snout is used to dig into the soil to find food and is a very sensitive sense organ.
Pigs have a full set of 44 teeth. The canine teeth, called tusks, grow continually and are sharpened by the lowers and uppers rubbing against each other.
Pigs that are allowed to forage may be watched by swineherds. Because of their foraging abilities and excellent sense of smell, they are used to find truffles in many European countries. Domesticated pigs are commonly raised as livestock by farmers for meat , as well as for leather. Their bristly hairs are also used for brushes. Some breeds of pigs, such as the Asian pot-bellied pigs, are kept as pets.

After the young are weaned, two or more families may come together until the next mating season.
Pigs do not have functional sweat glands,so pigs cool themselves using water or mud during hot weather. They also use mud as a form of sunscreen to protect their skin from sunburn. Mud also provides protection against flies and parasites.

Protect Your Dog From These Preventable Threats
Owning a dog is one of the most rewarding experiences a person can have in their lifetime, but having a dog is much more than the occasional walk around the block or playing fetch in the yard. There are many other responsibilities that one must consider in order to be a good dog owner. Your dog’s health is a major concern to any good pet owner and in this article we will concentrate on some preventable threats to your pet.
As winter ends and spring starts, so do different types of threats to your dog. Obviously, as the weather starts getting nicer, your pet spends more time outdoors and is more susceptible to the these threats. It is important to be alert for ticks, mosquitoes and micro organisms that spread diseases that are harmful to your dog’s health. Ticks normally live in wooded areas or in tall brush and do not transmit bacteria through the air, but by biting the dog. Some other threats are summarized below:
Lyme disease- is a tick-borne bacterial disease and it can cause lameness, kidney damage and death.
Leptospirosis- this is the #1 cause of acute renal failure, “lepto” is a deadly bacterial disease that is spread by contact with urine from other pets, wildlife and livestock and can be transmitted from dogs to people.
Rabies- is a fatal viral disease transmitted by saliva most often through bite wounds and is a threat to both humans and animals.
Heartworm Disease- is a mosquito-borne disease that is preventable and attacks multiple organs and will cause death if untreated.
As a dog owner, there are many things you can do to minimize the risk to your pet. Brush your dog often and visually inspect your animal especially after an outing in the woods. Additionally, use tick and flea treatments and medications that your veterinarian recommends to kill these harmful pests. Furthermore, your veterinarian can suggest how to protect your pet from lyme disease through vaccination.
There is another important factor in taking care of your dog: twice-a-year wellness exams. You see, dogs age faster than we do and major health changes can occur in a short amount of time. Moreover, your dog is living longer, which increases the chance of potentially serious illnesses during their lifetime.
These wellness exams can help your veterinarian diagnose, treat or prevent problems before they become life threatening. Additionally, these exams allow the veterinarian to discuss nutrition, your dog’s behavior or other concerns you may have.
In return for all this attention, your dog will reciprocate with unconditional love, friendship and affection. Try to educate yourself to protect your dog from these and other harmful threats. If we were to think in terms of finances, what a wonderful return on your investment!

Animal lovers are never lonely
Early childhood is an impressionable period of life in which children are often dog lovers. Parents have a great contribution in the building of their children’s character by encouraging them to be animal lovers and allowing them to have a dog as a pet. Parents should encourage their young to become animal lovers because this will mean never to be alone, to always have a friend, to be comforted when sad, to be happy and needed, to learn responsibility and, last but not least, to love. That's what an animal friend teaches a child: the most valuable lesson of all.
Seeing dog lovers in parks, on television, in stores and on the streets, one can realize the benefit of having a pet as company. Having a dog or cat around the house will surely bring animal lovers a lot of smiles. Cuddling, big round eyes sending messages of love, cute fluffy ears or tail moving in signs of joy should make any heart melt. Animal lovers are the ones that feel for these helpless beings. A pet is not an object one buys to keep around the house, but a living thing that communicates and interacts with the persons around it. Animal lovers know that and they appreciate every smile a pet brings on their faces.
Dog lovers know that pets depend and need them more than a human ever will. The animals around the house have to be fed and watered and cleaned constantly, just like a child. They need their masters just like a child needs his mother to survive. Having a pet means having a lot of responsibility and dog lovers sacrifice their time, money and effort to keep their beloved company around them. Animal lovers assume the responsibility towards their pets with pleasure and never regret their efforts, because they do it out of love. In exchange, animal lovers receive even more. Animal lovers are never lonely, are always loved by their pets, they never get disappointed and often receive the comfort that a human could not give them. Not to mention animal lovers won't ever feel nagged by their pets, neglected or left aside. Having an animal for a friend is having a true friend for life.
Another reason to why animal lovers are never lonely is the fact that their sacrifices talk a lot about the kind of persons they are: communicative, generous, not selfish, always around to help their friends in need, loving and attentive. There are many people who would want these qualities in their friends or their lovers, so animal lovers are very appreciated and loved by everyone. Single persons that are dog lovers can easily find company not only in their animal friends, but in their human friends also. Not to mention that dog lovers usually find dog lovers also as their friends, because their passion for the same pets will give them a lot of things in common to talk about. A shared passion (of any kind) will always bring two persons together. Imagine a dog lover going out to walk the dog every day. Who is he most likely going to have as a friend? Will it be his female neighbor that can't stand dog lovers? Or will it be the girl that walks her own dog in the park every morning just like him? Animal lovers, because they love life and its smallest proofs (animals) will never be alone and they will always share their pleasure with those that appreciate the same thing as them.
So if you are looking for company, animal and human, don't forget animal lovers and their pets! They will bring you the soul medicine everyone needs: love.
