Do Dogs Get that Eureka! Feeling?

New research by Ragen McGowan et al (University of Agricultural Sciences, Sweden) investigates whether dogs enjoy the experience of solving a problem in order to obtain a reward, or if it is just the reward itself that makes them happy.

Rather unusually, the idea came from a study that found cattle who completed a task to earn a reward seemed to be happier than those who just received the reward. The design of McGowan et al’s study is very similar, but adjusted for dogs.

The results show that when dogs solved the problem and earned a reward they wagged their tails more and were more eager to repeat the experience than if they were just given a reward. The study also found that food was a preferred reward over time with another dog and petting from a familiar human.

Six matched pairs of beagles took part (12 dogs in total). Each dog was an experimental dog for half of the time, and a control dog for the other half of the time.

The study used six pieces of equipment. When manipulated correctly by the dog, each made a distinct noise that would show the task was complete. The equipment included a dog piano that had to be pressed to play a note, a plastic box to be pushed off a stack so it would noisily hit the floor, and a paddle lever that would make a bell ring.
