A perfect follow-on to yesterday’s post.

Those that read my post from yesterday will understand that it was both a busy and wonderful day. Topped off beautifully by arriving home to find four proof copies of The Book!

So it was well after 5pm yesterday when I sat down to publish today’s post.

It seemed very appropriate to offer a recent item that appeared on Mother Nature Network and is republished here within MNN’s terms.

(Please note that I didn’t have the time to copy and insert the many interesting links in the original but have coloured the words or phrases to indicate that by going here you can access those links.)

The science behind how dogs play

When dogs bow or let another dog ‘win’ the wrestling match, there’s a good reason.

By: Laura Moss, October 29, 2015.

Dogs play by chasing, tackling and nipping at each other, but there’s more to their lively antics than meets the eye. The way dogs interact with one another reveals that dogs have a language as well as a moral code, and they don’t engage in play simply to establish dominance.

Marc Bekoff, professor emeritus at the University of Colorado at Boulder, has been studying animal behavior for more than 40 years. After reviewing four years’ worth of footage of dogs, wolves and coyotes, he discovered that even dogs’ wild relatives play by chasing each other, rolling over and jumping on one another.

“Play is a major expenditure of energy, and it can be dangerous,” Bekoff told The Washington Post. “You can twist a shoulder or break a leg, and it can increase your chances of being preyed upon. So why do they do it? It has to feel good.”

Bekoff and other researchers have conducted numerous studies on how these animals play and what their actions mean. What they’ve found is that dogs’ behavior during play is a language all its own, and every shift of the eyes or wag of the tail is a form of communication.

Play even has a set of rules, and if a dog breaks them — by playing too rough, for example — that dog may be excluded from group play. Bekoff says this response suggests that dogs enforce moral conduct, which means they’re capable of experiencing a range of emotions and even of recognizing these emotions in other canines.

What exactly do their different play behaviors mean?

Play bow

When a dog lowers the front of its body in a bow-like stance, this is an invitation to play. If your dog often bows to other canines you meet while out on a walk, it’s a good indication that your pup would like a playmate.

However, this stance doesn’t only invite play. It also communicates to other dogs that the jump, nip or roughhousing that follows the bow isn’t an act of aggression. It’s simply a dog’s way of saying, “I’m just playing around.”

Rolling over

When a dog rolls over onto its back during play, it’s often considered a submissive gesture; however, research suggests it could mean something else entirely.

Earlier this year, scientists at the University of Lethbridge and the University of South Africa observed 33 play sessions between two dogs, and they also studied 20 YouTube videos of dogs playing together.

While not all the dogs rolled over during play, those that did weren’t necessarily the smaller or weaker of the two dogs, nor were the dogs that rolled over exhibiting submissive behaviors such as decreasing play.

In fact, smaller dogs were no more likely to roll over than larger ones, and the pups that did roll over used the position to evade a nip or to get into position to playfully bite the other dog.

The researchers found that none of the 248 rollovers were submissive during play and concluded that rolling over is actually meant to facilitate play.

Letting female puppies win

A 2008 study found that male puppies frequently let their female puppy playmates win during play, even when the males were bigger and stronger.

The male dogs would even put themselves in positions that left them vulnerable to attack. For example, the male puppies would occasionally lick their playmates’ muzzles, which provided the female puppies with an opportunity to easily bite in return.

Why? Researchers say the act of playing may be more important to the male dogs than winning.

“Perhaps males use self-handicapping with females in order to learn more about them and to form close relationships with them — relationships that might later help males to secure future mating opportunities,” Camille Ward, lead author of the study, told NBC News.
