How do dogs speak?

Dogs have developed a complex system of vocalizations and body language over thousands of years of domestication and evolution. While they do not have a spoken language like humans, dogs are able to communicate their needs, wants, and emotions through sounds, facial expressions, and postures. Understanding how dogs “speak” is key to building strong relationships between dogs and their human companions.

Barking

Barking is one of the most well-known dog vocalizations. But barks can mean different things depending on the situation and what the bark sounds like:

  • Short, repetitive barks are an alarm call, meant to get attention
  • Low pitched, long barks are a territorial call, warning intruders away
  • High pitched, staccato barks are an expression of excitement

Context is important for interpreting barks. For example, some dogs will emit an excited bark when their owner comes home, which is different from alarm barking at a stranger. Puppies often practice barking, vocal experimentation that helps them learn the meaning of different barks as they mature.

Growling

Growling primarily signals a warning threat. It often occurs over guardable resources like food, toys, or sleeping areas. Mild, low growls are a dog’s way of saying “back off” before escalating to aggression. However, growling does not always indicate imminent attack. Some dogs will growl during play to signal it’s part of the game. Understanding your dog’s personality and the context of the growl is key to interpreting its meaning.

Whimpering and Whining

High pitched whimpers and whines are associated with stress, anxiety, and need. Puppies will whine when anxious or distressed from separation from their mother and littermates. Adult dogs may whine due to separation anxiety when their owner leaves. Excitement whining often occurs when a dog anticipates something positive like going for a walk or car ride. Dogs will also whine when in pain or needing something urgently. These vocalizations are a dog asking for support and care from their human.

Howling

This classic canine call is used for long distance communication in the wild. Wolves and wild dogs will howl to locate pack members who are far away. Howling also helps pack members find each other after becoming separated. For domestic dogs, howling remains an instinctual behaviour and they will often join in chorus howls with other dogs. It can be set off by certain triggers like sirens. But not all dogs are prone to frequent howling. Some breeds, like Huskies and Beagles, are more predisposed towards this vocalization.

Yelping

A loud, high pitched yelp is associated with pain and alarm. Puppies will yelp when play with their littermates gets too rough. Adult dogs will yelp if hurt suddenly like being stepped on or handled roughly at the vet. Yelping indicates urgent distress and a need for intervention to identify and resolve the cause of pain.

Growling and Grunting

Low, guttural growls and grunts are most common in male dogs. They signal a social challenge, dominance, or territorial claim. Intact male dogs defending their territory will emit these sounds most frequently. Grunting while playing is also a signal of having fun. Panting in between grunts indicates it’s all part of the game.

Body Language

Dogs rely heavily on body language to complement vocal communication. Eye contact, ear position, tail height and wagging all give important clues about a dog’s emotional state and intentions. Understanding canine body language is just as important as interpreting vocalizations when learning how to communicate with dogs.

Eyes

Dogs rely more on body posture signals than facial expression due to their physical structure. But eye contact and eye movement still provide useful information:

  • Direct eye contact is a dominant, challenging signal in dogs
  • Avoiding direct eye contact shows deference and communicates friendliness
  • Squinty eyes indicate happiness and affection for some dogs
  • Staring intently signals aggressive threat and dominance
  • Dilated pupils indicate high arousal and excitement

Ears

Ear position relates strongly to mood:

  • Ears forward and erect signifies alertness and attention
  • Ears rotated sideways or partially back indicates relaxed neutrality
  • Ears flattened and pressed tight to head signals fear
  • Ears erect and rotated forward is aggressive readiness

Mouth

The mouth conveys a lot through subtle signals:

  • Relaxed, slightly open mouth is a friendly, submissive gesture
  • Panting when relaxed shows calmness
  • Lip licking indicates mild stress
  • Yawning when not tired is mild stress
  • Snarling and teeth-baring preludes aggression

Tail

The position and motion of the tail reveals emotional state:

  • Slow, loose wag indicates relaxed positivity
  • Broad wag in full tail motion is excited happiness
  • Stiff, erect tail conveys alertness
  • Low, slightly wagging or tucked between legs signals uncertainty or fear
  • No wag, erect tail conveys dominant threat

Posture

Body posture as a whole communicates a lot:

  • Relaxed posture with loosely wagging or neutral tail signals comfort
  • Play bow invite with front legs extended and rear in the air is an invitation to play
  • Rolling over to expose belly indicates peaceful submission and trust
  • Crouching close to ground signals moderate fear, uncertainty
  • Defensive, low posture with erect, stiff tail shows potential aggression
  • Assertive stance with head high and tail erect displays dominance

Scent

Scent is a dog’s primary sense, so chemical communication through smell plays a major role. Dogs have an incredible sense of smell that allows them to detect emotional changes in other dogs that humans can’t perceive. Dogs also create chemical signals themselves to communicate status and mood:

  • Pheromones in sweat glands relay anxiety, confidence, dominance
  • Urine contains pheromones for territorial marking
  • Scent glands in feet secrete pheromones while walking

Chemical signals are especially important for communication between unfamiliar dogs. Scent provides information about reproductive status, health, and temperament that allows dogs to determine if the other dog is a friend or foe.

Breed Differences

While all dogs share common vocalizations and body language, communication does vary somewhat between breeds:

  • Sled dogs like Huskies howl more to communicate over distance
  • Herding breeds like Border Collies use intense eye contact to direct movement of livestock
  • Hounds track prey using their powerful sense of smell
  • Pit Bulls and other fighting breeds are more prone to stiff, dominant postures
  • Toy dogs tend to be more vocal in barking and whining

Understanding a specific breed’s typical tendencies makes interpreting their communication signals easier. But each individual dog will have their own personality and quirks too.

Conclusion

While dogs do not have a true verbal language, their use of sounds, scent, body language and facial expressions allows sophisticated communication of their needs and emotions. Paying close attention to all aspects of how dogs “speak” enhances the bond between humans and their canine companions. With time and patience, dog lovers can become fluent in translating barks, wags, growls and more into mutually understood conversation.
