A current day phenomena: a Canaan Dog seeking an owner! The authentic survivor, the Canaan Dog spent the first 4,000 years of its existence savage, without ever wearing a collar.
For some authors the Canaan Dog comes from the Spitz family, other lean toward understanding that this dog breed, originally from Palestine, lipoid type shepherds have intervened. It is a medium sized dog, square, with a height from 50 to 60 cm to the withers and a weight between 18 and 25 kg. The head is Spitz type, triangular shaped, with a round skull and light stop. The ears erect, with a wide base and rounded tip. The neck is clean, well arched and medium length. The hinds, straight and medium boned: a straight upper outline; the hindquarters, wide with strong thighs. The feet, round cat type, with hard pads. The tail high inserted, hairy, carried over the back. The color is from sandy to reddish brown, white or black with a dark or white. White patches on the body are common, although the gray and black and tan are not admitted. The coat is dense, rough and medium length. The hindquarters display abundant hair and males have crest.
Kelef K'naani, the “dingo” of the Promised Land, enjoys a longer pedigree than the Dead Sea Scrolls and can be counted amongst the most ancient of dogs. Despite its somewhat common appearance, it is smart and talented as any dog, and as the perfect wedding guest, it is not demanding. 
Israel’s national dog still doesn’t have many fans, despite proximity and exceptional breed personality. In Israel the Canaan Dog is praised for its versatility, intelligence and ideal size. Due to its skills as a shepherd, guardian, guide dog, trailing and rescue dog, mine detector and company dog, it is qualified to compete with any other dog. Its skills to “detect” deserve acknowledgement, and can identify and individual approaching from a great distance. Its protective instinct and strong bark make it a premium candidate for guardian tasks. Training requires patience and time since the Canaan Dog bores easily and doesn’t like to repeat. It is a thinking dog that likes to keep its mind and feet active and occupied. Be a good example for your Canaan: it learns watching.
Many Canaans are aggressive to other dogs, and fight is not controlled.
Given its history as a wild dog, it is by nature a mistrusting breed with strangers. Canaan Dog puppies are not as extrovert as others. The breed is very fond of the family but require socialization to accept strangers. 
The Canaan Dog puppy is born with 370 to 450 g and grows at a normal pace, healthy. Puppy weigh can vary considerably, since an adult can weigh from 18 to 25 kg. Few breeds are comparable with the Canaan for their naturality. The Puppy’s soft hair is thicker around six months. There is a suspicion increase during adolescence, although most Canaan Dogs go through this phase without problems. The Canaan Dog naturally mistrusts stranger. Puppies are extremely vocal, born with talent for languages; some speak Yiddish and Hebrew; others speak different languages; and other sing in typical Middle Eastern fashion. So much barking should be cut off early, otherwise it can become a problem. Breeders recommend socializing young.
Few veterinarian bills will be produced by the Canaan Dog. It usually lives more than most breeds and often continues active and agile well over 10 years. The healthiest dog on the face of the earth, the Canaan Dog would starve most veterinarians in the country. Its reputation as the only breeds that have evolved without the intervention of man leads us to believe that the Canaan Dog will give little health problems to their owners. A dog as natural as the Canaan Dog is not demanding. Its appetite is moderate; brushing and baths are reduced to the minimal or none; exercise requirements are easily met. As any dog with a double coat, it sheds twice a year. Minimal hip dysplasia and progressive retinal atrophy, the lowest in all breeds. Some cases of epilepsy are reported. Longevity is between 14 and 15 years, and some specimens have reached 20. Many owners point out that older specimens keep cheerful and active.
