(Phys.org) —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 their 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.
