Apparently it’s possible to identify the social ranking and personality traits of dogs.
In a recent study done by Dr. Mate Nagy of the Department of zoology at Oxford University, 6 dogs and their owners went on fourteen group walks that lasted between 30 and 40 minutes. The dogs wore harnesses that had GPS to monitor their movements.
The study found that it is not possible to determine the leader after a single walk, but after a number of walks the leader becomes clear.
Researchers feel that the information from this study may be able to help search and rescue groups decide upon which dogs will work best together, among other uses.
