In a study of 14,000 dogs, fully 73% of the dogs studied had unwanted behavior. One-third of the dogs studied had noise sensitivity. The other behaviors included fearfulness of people, other dogs and unfamiliar locations, fear of surfaces and heights, inattention and impulsivity, compulsive behavior, aggressiveness and separation anxiety. The most common were noise sensitivity, fear of surfaces and heights and general fearfulness.
Professor Hannes Lohi’s research group from the University of Helsinki conducted the study and found that fearfulness and aggressive behavior were linked to each other as well as impulsivity, compulsive behavior and separation anxiety. The researchers also discovered that many unwanted behaviors are inherited. Their hope is that better breeding may help eliminate these behaviors.
Author’s Note: The article states, “The problems appear to be quite breed-specific. For example, in Border Collies we observed more compulsive staring and light/shadow chasing, behaviours that occurred more rarely in all other breeds.” Studies such as this are interesting, however, it should be considered what the breed traits are, the excessive staring could actually be the Border Collie “eye.” Since Border Collies herd livestock, they may have a tendency to chase light and shadows if their instinctive herding needs are not met.
