Over the years appeared several legends regarding the dogs’ friendship with men. It is true that digs are very intelligent and devoted animals and they managed to enter the men’s lives like no other animals. This is why dogs become man's best friend.

Recently, researchers discovered that dogs have a sixth sense, which make them able to predict epilepsy seizures 2-4 hours in advance, by barking and acting crazy. Dogs can also detect diseases and point the exact place of the disease on the human body. The first breeds of dogs especially trained for these missions were the Spanish picard, the British setter and the British pointer.
Dogs are always cheerful, at least when the environment allows them to be so. They are nocturne, as well as diurnal animals, and their main feature is that they are very sociable and they really enjoy the company of people. Dogs eat almost any kind of aliments, but their food is mainly adjusted depending on the region. In Norway, dogs are fed with fish and in France people happily feed them with grapes. They are a wonderful company and love jumping and running. They have quick senses, but the most important is the olfactory one.
There are not many things to be said about their intellect, because it is well known that dogs are intelligent animals which can easily be taught and trained. Dogs can live up to 20 years. One of the biggest concerns regarding the life expectancy for men as well as their best friends, dogs, is the increasing number of patients with cancer. Even if dogs cannot talk, it seems that they can help doctors understand better this disease, especially the way it develops. This can only lead to discovering new efficient treatments for men, as well as for dogs.
Just as people can develop stomach cancer, there can be stomach cancer in dogs. During the “Curing cancer in dogs- a benefit for people” symposium, which took place in London, it was stated that the study of tumors in men and dogs will makes understand better their pathogenesis. This includes stomach cancer in dogs, as well as in men. Even if it seems weird, it was stated that cancer treatments used for dogs can be as well used for men and children.

Cancer is the main cause of death among dogs aged more than 2. The cases of stomach, bone or skin cancer are increasing among men, as well as in dogs, and the most logical explanation is that we share similar genes. Some breeds of dogs are more predisposed to certain types of cancer. For example, Greyhound and Rottweiler breeds are more predisposed to bone cancer.
