Why dogs tilt their heads: Pups tip their faces to one side to help them hear and process their owner’s requests more easily, 研究发现
It’s an adorable behaviour that will tug at the heart strings of any dog lover – but why exactly do dogs tilt their heads to one side?
Researchers from the Eotvos Lorand University in Budapest set out to answer this question, and suggest that tilting the head may help dogs to hear and process information more easily.
In their study, the team carried out a series of experiments involving dog owners teaching the name of new toys to their pets.
They found that dogs tilt their heads upon hearing their owners requesting a toy, with the side of the tilt seeming to be consistent for each dog over time.
‘Often owners observe dogs tilting their heads and we still do not have a full understanding of the function and circumstances in which this behaviour happens,’ the researchers explained in a statement.
'然而, this study is the first step in this direction showing how this behaviour could be related to the presence of meaningful and salient auditory stimuli for the dog.’

Which breeds of dog are the smartest?
WebMD reports that the following are the most naturally intelligent dog breeds:
- Border Collie
- German Shepherd
- Golden Retriever
- Doberman Pinscher
- Shetland Sheepdog
- Labrador Retriever
- Australian Cattle Dog
Many animals – including humans – regularly use asymmetrical behaviours.
例如, you might squint with one eye to study an image, or turn your head a certain way to hear better in response to a noise.
与此同时, in dogs, asymmetrical behaviours include tail wagging, nostril use while sniffing, or even paw preference.
‘Tilting the head is yet another asymmetrical movement in dogs, but it had never been studied,’ explained lead author Dr Andrea Sommese.
‘We investigated the frequency and direction of this behaviour in response to a specific human verbal vocalization: when the owner asks the dog to bring a toy by saying its name.
‘We did so after realizing that it often happened when the dogs were listening to their owners.’
To understand this behaviour, the researchers analysed videos from a previous study, which looked at toy memory in dogs.
在研究中, toys were placed in one room and the owner and experimenter in another, before the owner asked the dog to fetch a specific toy by saying its name.
的 40 dogs tested, 33 were found to be typical dogs that could not learn the name of even two toys, while seven, including Whisky (图为) were classed as Gifted Word Learners, who could remember multiple names easily

The Gifted Dogs were also seen to regularly tilt their head upon hearing the owner’s request for a toy, while the typical dogs rarely did.
This prompted the team to carry out two further experiments to observe head tilts only.
The subsequent experiments, which spanned over 24 月, confirmed that dogs seem to have a preferred side when it comes to head tilts.
‘It seems that there is a relationship between success in retrieving a named toy and frequent head tilts upon hearing its name,’ said Shany Dror, co-author of the study.
‘That is why we suggest an association between head-tilting and processing relevant and meaningful stimuli.’
狗首场比赛关于 20,000 至 40,000 几年前
对世界上最古老的已知狗遗骸进行的基因分析表明，狗是由居住在欧亚大陆的人一次驯化的, 周围 20,000 至 40,000 几年前.
克里希纳·维拉玛博士, 石溪大学进化学助理教授, 告诉MailOnline: ‘狗的驯化过程可能是一个非常复杂的过程, 涉及几代特征性狗的特征逐渐演变.
‘那些更温和，不那么凶悍的狼在这方面会更成功, 虽然人类最初并未从此过程中获得任何好处, 随着时间的流逝，他们会发展出某种共生关系 [互惠互利] 与这些动物的关系, 最终演变成我们今天看到的狗。’
