Are All Dogs Man's Best Friend? Study Pinpoints Friendliest, Most Sociable Breeds

While dogs are generally known to be man's best friend, a new study reveals that not every dog breed showcases the same level of friendliness and human sociability. Some dog breeds enjoy the company of humans more than others.

Man's Best Friend

Per MailOnline, researchers have looked into the dog breeds that have the lowest and highest human sociability levels. The researchers from the University of Helsinki looked into canine personalities to see if there were any interbreed variations.

Dr. Milla Salonen, the study's leader, explains that the dog breed was the most important factor that determined any underlying differences in terms of personality, Earth.com reports. Each dog is an individual creature, and each breed has various sets of traits. However, dog breeds vary in terms of the personalities that the dogs belonging to the breed have, according to their study.

Their research showed that bull-type terriers, teacup dogs, and golden retrievers were all list-toppers when it came to human sociability levels. This affirmed the status of these creatures as "man's best friends."

Personality Differences in Dog Breeds

On the other hand, livestock guardian dogs, primitive sighthounds, and Asian primitive breeds were all found to enjoy human company the least.

These findings resulted from analyzing an extensive behavioral dataset that covered the data of 11,000 dogs and 300 different breeds. The researchers then sorted the dogs into 52 different groups.

Cautious examination revealed that the data had strong links between dog breed and seven different personality traits, namely, aggressiveness or dominance, training focus, insecurity, dog sociability, energy, perseverance, and human sociability.

Bull terriers were at the forefront of the human sociability aspect, while teacup dogs, retrievers, Jack Russell terriers, and Dachshunds closely followed behind them.

Livestock guardian dogs, on the other hand, were the least social breeds. Following them were Asian primitive breeds, primitive sighthounds, northern hunting spitzes, sled dogs, and Pinscher/Schnauzers.

The researchers also looked into other factors, aside from breed, that may affect human sociability. Their findings revealed that female dogs were generally more sociable compared to male ones and that human sociability plummeted as the dogs aged over time.

The results thus suggest that, from their pets' early age, new pet owners should intentionally expose their pups to social environments where humans are involved. These pups should become familiar with unfamiliar animals, places, and people. However, the pup should determine the conditions for socialization and should not be forced to face and endure frightening situations.

Prior to this, researchers from the University of Helsinki had also examined the intelligence levels of dogs and looked into which breeds were the smartest. Per NDTV, the researchers found out that the Belgian Shepherd was the smartest dog breed.

中文简要说明：

狗狗全是人类的好朋友？一项芬兰研究显示，牛头梗犬、茶杯犬、黄金猎犬等是对人类最友善的狗狗种类，是名副其实的「人类好朋友」，不过牲畜护卫犬、亚洲原始犬种、原始视觉型猎犬最不爱人类陪伴。

综合英国《每日邮报》（Daily Mail）、「The Science Times」报导，芬兰赫尔辛基大学（University of Helsinki）团队的研究成果于5月19日发表在期刊《iScience》，研究人员一共搜集300种不同品种、共约1.1万只狗的行为调查数据，后续再将这些狗狗约略分类为52种。

研究结果显示，不同品种的狗和7大性格特质有强烈关系，这7大特质包括不安全感、训练专注度、侵略性/主宰性、活力、和狗的社交能力、和人类的社交能力，以及毅力。

研究发现，在与人类的社交能力方面，最亲人的5种狗依序为「牛头梗犬」（bull type terriers）、吉娃娃、博美、贵宾等体型较小的「茶杯犬」、黄金猎犬、杰克罗素㹴，以及腊肠狗。

另一方面，如边境牧羊犬等牲畜护卫犬（livestock guardian dogs）、松狮犬等亚洲原始犬种、原始视觉型猎犬、北方狩猎狐狸犬、雪橇犬、雪纳瑞等最不爱人类陪伴。

除了品种，研究也发现母狗比公狗更亲近人类；年龄也是因素，狗狗年纪愈长，与人类互动的活力也会下降。研究因此建议，不论品种，饲主可试着尽早让毛小孩熟悉人类。
