Dogs express their emotions with their bodies, but we’re not always able to correctly interpret the messages they’re sending. Or worse yet, we misunderstand their intent, which can make a challenging situation even worse.
Learning to read what your dog is communicating is one of the most important things you can do to strengthen your relationship with them. While every dog will have their own unique nuances to their communication style, most dogs rely on similar postures to convey how they’re feeling.
When reading a dog’s body language, it’s important to note that the dog’s entire body plays a role in signaling; for example, a wagging tail doesn’t necessarily mean that a dog is happy, especially if the rest of their body is stiff.
Everything from your dog’s ears and expression on their face to the placement of their feet, and of course, the tail, work together to help communicate your dog’s emotional state.
Here are some dog body language basics to help you understand what your dog is trying to tell you.

[5/6/08] While looking up dog play, I came across this article on dog body language at wagntrain.com. The article also touches on Turid Rugaas and Calming Signals.
Turid Rugaas, a dog behaviorist from Norway, points out that dogs, as pack animals, have highly-developed ways of avoiding and diffusing conflict and aggression. Dogs therefore use "Calming Signals" to reduce stress for themselves and others they interact with (including humans). Calming signals include: Yawning, looking away, lip-licking, moving slowly, circling, sniffing the ground, becoming "distracted", sitting or lying down. Some of them are also the "appeasement display" behaviors that are developed to turn away aggression and threats of aggression - these are often confused with "the guilty look" that dogs may appear to be giving when scolded for doing something. Note that most of these are the opposite language from the directed attention that would be found in an aggressive interaction.
They have a number of additional informative articles in their Training Tips section.

dog years
Dogs do not simply age at seven times the rate of humans, scientists have found in a study that reveals young dogs might be “older” than previously thought.
The findings suggest a one-year-old puppy is actually about 30 in “human years” – an age when humans, at least, might be expected to have stopped running riot with the toilet paper.
Writing in the journal Cell Systems, researchers at the University of California San Diego School of Medicine describe how they focused on epigenetic changes to DNA – modifications that don’t change the DNA sequence but can switch genes on or off.
In particular the team compared the way the particular molecules, called methyl groups, accumulated in certain areas of the human genome over time with how they accumulated in similar areas in the dog genome.
The results, which draw on genetic data from about a hundred labrador retrievers from puppies to elderly animals, reveal every human year is not equivalent to seven dog years.
Instead the situation is more complex, with dogs showing far more rapid accumulation of methyl groups in their genome than us within their first year or so, suggesting they age at a much faster rate. However the rate of ageing in dogs, compared with humans, slows down as the years roll by.
Indeed, the findings suggest a one-year-old dog would have a “human age” of about 30, while by the age of four they’d be about 54 in “human years” and by 14 years old they would be on a par with a human in their mid-70s.
The relationship, the team say, is described by the formula: human age = 16 ln(dog_age) + 31. In maths, ln refers to the natural logarithm of a number.
The team say the work now needs to be repeated in other breeds of dog. But, they say, for young and old dogs, the relationship seems to reflect the ages at which humans and dogs experience particular milestones.
“For instance, the epigenome translated seven weeks in dogs to nine months in humans, corresponding to the infant stage when deciduous teeth erupt in both puppies and babies,” the team wrote in a preprint of the study. “In seniors, the expected lifespan of labrador retrievers, 12 years, correctly translated to the worldwide lifetime expectancy of humans, 70 years.
Prof Lucy Asher, an expert in canine puberty at Newcastle University who was not involved in the research, welcomed the study.
“If we think about ageing in terms of how old our cells are, this new paper is really useful in matching up human and dog years,” she said, adding such biological ageing is important for medical and veterinary health.
But, Asher added, the match breaks down if ageing is considered in terms of behaviours, hormones or growth – meaning we shouldn’t be surprised at the escapades of young dogs.
“Whilst a 30-year-old human might have cells of an analogous ‘age’ to a one-year-old dog, many dogs won’t be fully grown at this time and they will still have unsettled hormones and behaviour associated with puberty,” she said, noting that one-year-old dogs act more like human teenagers.
“The development of dogs is not just a shortened version of the human development, which is why it’s difficult to find a clear match-up between a dog’s age and a human’s age.”
