But choosing dogs based on a Hollywood story can often be problematic. "If people buy en masse dogs because they appear in movies the consequences can be negative for the dogs themselves," Alberto Acerbi, an anthropologist at University of Bristol states."Our previous study found that the most popular breeds had the greatest number of inherited disorders."
The effect appears to be decreasing over time - with more films about dogs, as well as TV and the internet, the influence a specific piece of media has on dog ownership shrinks. That doesn't mean canine cinema can't be a force for good, with the press around Tom Hardy's "The Drop," for example, showcasing a softer side of the oft-maligned pit bull.
"It's not surprising that we tend to follow social cues and fashions, as this is a quite effective strategy in many situations," Acerbi says. "However, in particular cases the outcomes can be negative. When choosing a new pet, we may want to act differently."
That means taking the time to figure out if you can commit to owning a dog. And if you can, the best way to pick a pooch isn't from a theater - it's from a shelter.
