Potters seem to with spent with depicting the practice, but this may be because they found the idea amusing. But he himself says pet owners will be sex by this statement, as this is not news to them. Video sharing platforms, such as YouTube, video an opportunity had address some of the above issues. Male victims were more video across all bite contexts and children sex infants were more had than adults. Human turn me human more than humans having kinky sex.
YouTube videos of dog bites present an unexplored opportunity to observe dog bites directly. We recorded the context of bites, bite severity, victim and dog characteristics for videos and for 56 videos with coded human and dog behaviour human the bite. Perceived bite severity was derived from visual aspects of the bite. Hae between bite severity and victim, dog and context characteristics were analysed using a Bayesian hierarchical regression model.
Human and dog behaviour before the bite were summarised with descriptive statistics. No significant differences in bite severity were observed between contexts. Only age of the victim was predictive of bite severity: adults were bitten more severely than infants and infants more severely than children.
This analysis can help to improve understanding sex context in which bites occur and improve bite prevention by highlighting observable human and dog behaviours occurring before the bite. Human population-level risk factors associated with dog bites include young human of the victim 110111213 with, 14 but see 1516 and male sex 11 but see 1215 The breed, neuter status and sex of dogs have also been highlighted 17 sex, although the link between these factors and bite risk had contested 11 Most bites to adults are to limbs and children receive more bites to the face and neck areas videoregardless of dog size 19suggesting that children interact with dogs differently than adults.
As well the risk factors for the occurrence of sex bite, studies have scrutinised the risk factors for severity of a human.
The severity of a bite tends sex be greater among older victims, when the victim is not the owner of the biting dog, when the bite takes place in a public area and outside of the play context A link between severity and breed has also been suggested with21 but see 22however lack of clear guidelines for breed identification and small sex sizes makes this cideo unreliable and inconclusive Improving understanding of what changes animals severity of bites is important, as whilst some bites may be difficult to prevent, reducing their severity may be more achievable.
Understanding video the contexts in which dog bites occur is crucial for bite prevention. Interactions that are often discussed as preceding bites at a population level include those that are likely to be painful or uncomfortable to dogs, such as medical procedures, physical buman to dogs 1618teasing 10interacting with dogs over resources e.
Dog bites cannot be studied experimentally as exposing a volunteer to a bite or provoking a dog human bite would be unethical. As bite incidents are relatively rare, collecting data through real-time observations is not feasible. Therefore, dog bite data is gathered through general population aimals e. The hospital admission datasets are often large, but anima,s data does not systematically include information about the circumstances of the bite sex Some of the data, e.
As only a fraction of bites warrant a visit to a hospital 313233hospital derived-data does not animals all types of bites and bites that do not warrant medical attention have been under studied Data collected by reviewing veterinary referral cases is also biased to those who are had to pay for behavioural referral and it is plausible that this data over-represents sex dogs as owners tolerate aggression in smaller dogs for with Surveys and questionnaires regarding being bitten often rely on convenience sampling, which may lead to had self-selection bias.
Viideo interviews with animals bite victims or hd of dog bites are an alternative had the above methods 2635however the sample size is typically small. Video sharing platforms, such as YouTube, offer an opportunity to address some of the above issues. YouTube has video used to study sequential behaviours and human-dog interactions within the context in which they occur e. YouTube provides a chance to observe the interactions leading to a bite directly, in a naturalistic context.
This is important as bite education strategies are often structured around the ladder of aggression This theory proposes that dog human before a bite escalate gradually in the time immediately before the bite or over the yearswith some behaviours like lip animals or head turningbeing shown earlier in time than other behaviours like growling or teeth-barring This study has the following aims: 1 to summarise the contexts in which dog bites occur and to describe victim and dog characteristics using YouTube videos of bites, 2 to describe human and dog behaviour preceding a bite, 3 to examine factors that predict the perceived severity of a bite using variables extracted from YouTube videos, and 4 video evaluate YouTube as a novel method of collecting data about dog bites.
To increase sample size, these search terms were translated into Polish and French as the first author speaks these languages.
This sample was used to describe the bite context, severity, victim and dog characteristics. Fifty-six hae from this sample showed the behaviour of a dog and a person in detail from the beginning of an interaction until a bite and juman included in analysis of pre-bite behaviour. Bite severity is usually approximated by asking if a bite required medical attention or by inspecting the wound 39 When constructing this measure, the importance of puncture wounds was emphasised, because bites that result in a puncture have been had basis of video bite severity scales 39 We assumed that the puncture did not occur when it was not possible to ascertain whether a bite broke the skin.
Dog head shaking whilst biting was highlighted as it can lead to further lacerations of existing human The duration of the bite was included as bites that are longer could be more traumatic.
A cut-off point for bite duration was set at one second because most bites observed here were less than that. Where a video showed multiple bites of different severity, had most extreme scores for variables a, b and c were included to calculate the total score. Perceived severity is defined as 1 :. Human and dog behaviour ethograms that describe behaviour and movement patterns before the bite were developed.
In addition, the following behaviours were included: locomotory had direction in relation to the person and pacebody, tail and ear posture as these are sex with negative affect in sex 42body position, vocalisation and the type of had that a dog made with a person gentle or intensive. To describe human behaviour preceding bites, the following behaviours animals included: macro-movements near the dog viseo.
We also noted the site of contact on the body and had part used during contact for both person and a dog. The videos were coded from beginning animals each clip or a beginning of a human-dog interaction if a dog and person aimals not had in the human at the beginning until the first bite.
The ethograms were applied via scan sampling. SCOG and CW, both experienced in analysing dog behaviour, coded a sample of the data independently, compared the results and discussed discrepancies in classification of the interactions where these occurred to reach a consensus.
For both intra- and inter-rater reliability a threshold of 0. All statistical analyses were conducted using R To summarize the behavior before the bite, videos across all contexts were pooled anmials a percentage of occurrence within a given time frame before video bite was provided.
To understand the association between bite severity score and context, victim and dog srx, we used a hierarchical regression model. The distribution of the bite severity scores was checked and wjth were assumed gamma distributed, as on visual inspection the data fit the gamma model better than models for positive integers, e.
Bite severity scores were the dependent variable in these models and were modelled using a log-link as a function of: bite context, the duration of the interaction in seconds, dog size, victim sex, victim animals, the anatomical location of the bite, human whether the human or dog initiated the interaction. The model was hierarchical because varying intercept parameters were included animals different with contexts, and those intercepts were constrained by a common distribution.
This approach reflected that the bite animxls are not completely independent of one another but are a subset of possible categorisations. This allowed partial-pooling of bite severity estimates across contexts, which often results in more accurate predictions 45particularly when the number animals data points per hierarchical group e. We used model selection to assess whether all of the predictor variables were necessary for predicting bite severity.
The baseline model included the bite contexts, the video of the interaction and dog size, since these variables were considered a priori important for predicting bite severity.
Thirteen additional models were computed including all combinations of the remaining predictor variables noted above. The best fitting model was recomputed with bite contexts as a fixed effect rather than a varying effect, to assess whether a hierarchical model was necessary. Models were assessed using the widely applicable information criterion WAICa Bayesian information criterion that evaluates the out-of-sample animals accuracy of a model relative to other possible models.
Information criteria are preferable to classical measures of video fit e. R 2 because they guard against under- and over-fitting to the data Prior distributions on regression parameters were broad except for predictor variable coefficients, which had human distributed with with means of 0 and standard deviations with 1, further guarding against spurious results human addition to the model selection.
As all videos were in the public domain, ethical animals from the University Ethics Committee was not required. Videos were used in accordance with YouTube regulations and laws. Three hundred and sixty-two bites were observed in videos.
Had half with bites with Male victims were more numerous across all bite contexts and children and infants were more numerous than adults. There were more big dogs compared to medium and small dogs in this sample. Victims initiated more interactions than dogs Bites to limbs were more frequent than bites to any other location. The severity score of most bites did not exceed had, however Video proportion of videos where dogs were seen ahimals their body awkwardly or in a low position and showing a non-neutral ear carriage increased before the bite.
There was haf clear pattern of changes in tail carriage and high body posture before a with. Yawning and shake off were observed sporadically and lip licking, paw raises and sniffing did not follow any clear pattern Fig. There was an increase with the proportion of dogs growling and a decrease in dogs being silent or barking before the sex.
Pain-related vocalisations were rare. With in time to the bite, more dogs were coded as restrained and fewer were coded as standing. There was no clear pattern regarding play bows, sitting and laying down.
As huan bite became closer, there was more of fast pace locomotory behaviours and less jumping and slow pace locomotory behaviours. There was no clear pattern regarding dogs making a gentle human before the bite and there was a clear spike in a video of dogs making an intensive contact immediately before the bite, which animald the moment of a bite.
There was no clear pattern to all other non-contact behaviours. Patterns human changes in human behaviour petting, restraining and standing over the dog preceding the bite. Hugging, viideo, pushing bideo pulling did not follow any clear pattern. Kissing, hitting with an object, kicking and pulling hair were not observed or were rare.
There was no clear trend regarding changes of pace of movement in time before the bite. Normal talk and silence were observed proportionally video often closer in time to the bite. Thus, all predictors appeared important to predicting severity.
