However, empathy for abused children was about the same as that for the canines, researchers said.
"Contrary to popular thinking, we are not necessarily more disturbed by animal rather than human suffering," said Jack Levin, Professor of Sociology and Criminology at Northeastern University.
"Our results indicate a much more complex situation with respect to the age and species of victims, with age being the more important component.
"The fact that adult human crime victims receive less empathy than do child, puppy, and full grown dog victims suggests that adult dogs are regarded as dependent and vulnerable not unlike their younger canine counterparts and kids," said Levin.

Participants randomly received one of four fictional news articles about the beating of a one-year-old child, an adult in his thirties, a puppy, or a 6-year-old dog.
The stories were identical except for the victim's identify. After reading their story, respondents were asked to rate their feelings of empathy towards the victim.
"We were surprised by the interaction of age and species. Age seems to trump species, when it comes to eliciting empathy. In addition, it appears that adult humans are viewed as capable of protecting themselves while full grown dogs are just seen as larger puppies," Levin said.
As for considering the opinions of 240 college students, Levin said it is common practise to use homogeneous samples for studies such as his that center around an experiment.
