human and puppy bonding together
The study observed 500 beagles with previous experience around humans, and then presented the beagles with a problem. The problem was to open a sealed container that has food in it, and when they accepted it was too difficult, they observed if the beagles turned to human contact to solve the problem. Of the 500 beagles studied, 200 of them were selected to have their DNA studied using a genome-wide association study (GWAS). The GWAS is able to find out if a particular gene variant is present in the dogs who exhibit a specific trait. A direct correlation was found using this method which determined that there actually were gene variants for the dogs who seeked human contact. Further support for this hypothesis would be if they performed this experiment on different dog breeds and still got similar results.
