Flat-faced dogs might get more human help thanks to their baby faces

Flat-faced or brachycephalic dogs breeds such as English and French bulldogs may be likely to display "helpless" traits by looking at humans more often than a longer-muzzled dog breed during a food retrieval task, suggests a small study published in Scientific Reports.

The increased engagement with humans and lower levels of task success may make people consider these breeds as "infant-like," which may partially explain their continuing popularity as pets despite noted health problems, according to the authors.

Dorottya Ujfalussy and colleagues assessed how the behavior of 15 English bulldogs and 15 French bulldogs compared to that of 13 Hungarian Mudis (a herding dog with a mid-length muzzle) during a task in which the dogs had to try and open three boxes to retrieve a piece of food.

The boxes involved different opening techniques, varied in difficulty (with Box A being the most challenging), and were presented to the dogs in a random order. All dogs observed the experimenter place a piece of Viener sausage in the box and were then given two minutes to attempt to open the box. During this time, the experimenter and the dog's owner stood behind the dog out of direct sight.

Both English and French bulldogs were successful at opening the box 93% less often than Mudis. Successful Mudis were also quicker than successful bulldogs; by the time one minute had elapsed approximately 90% of Mudis had opened the box compared to approximately 50% of bulldogs. However, compared to Mudis, English and French bulldogs were 4.16 and 4.49 times as likely to look back at the people than Mudis.

The authors suggest that these findings indicate a propensity for short-faced dogs to seek out human assistance when faced with problems, which may in turn promote a stronger social relationship between owners and these breeds of dogs due perceived helplessness. However, this study could not establish whether flat-faced dogs are genetically predisposed to appear more dependent on humans than other dogs, or whether owners' attitudes towards flat-faced dogs encourages dependent behavior.
