New research published in PLOS ONE has found the effect of movies on the popularity of certain dog breeds can last for periods of one, two, five and even 10 years. According to the University of Bristol, trends were also found to be directly linked to the success of the movie itself.
Earlier movies, such as the 1943 Lassie Come Home, were associated with larger trend changes than more modern films. In the two years after Lassie Come Home came out, collie registrations rose by 40 per cent. The 1959 Disney movie, The Shaggy Dog, led to a 100-fold increase in registrations of old English sheepdogs. The 10 movies with the strongest 10-year effect resulted in 800,000 more dogs being registered in the decade after the release of the movie than pre-release trends would have predicted.
Scientists say trends did not appear to be influenced by desirable traits, greater longevity or the number inherited conditions in certain breeds. In fact, the most popular breeds were found to have the greatest number of inherited disorders.
