A team of researchers in the United States has found that dogs appear to gain a “high” from running, similar to the well known “runner’s high” experienced by people who run or jog frequently.
In a paper published in The Journal of Experimental Biology, the group describes how they measured neurotransmitter levels in humans, dogs and ferrets as they moved on a treadmill to determine neurobiological reward levels.
To find out, the team enlisted the assistance of some human volunteers, several dogs and some ferrets. Each was put on a treadmill set at a pace fast enough to simulate running. Afterwards blood samples were taken. In analyzing the results, the researchers found elevated levels of eCBs for both the humans and dogs, but not in the ferrets. In another test, the researchers slowed the pace of the treadmill to just a walk for the dogs and humans and found no change in eCB levels.
