Dogs have a sophisticated communication system that includes body language, vocalizations, and scent signals. Understanding how your dog communicates is essential for building a strong bond and preventing misunderstandings that can lead to behavior problems.
This comprehensive guide will help you interpret your dog's signals, understand what they're trying to tell you, and learn how to communicate more effectively with your canine companion. For more information on dog behavior, check out our complete guide to dog behavior.

Canine Body Language Basics
Dogs primarily communicate through body language. Understanding the basic components of canine body language will help you interpret what your dog is feeling and intending. According to the American Kennel Club's guide to dog body language, dogs use their entire bodies to express themselves.
The Overall Body Posture
A dog's overall body posture provides important clues about their emotional state:
Relaxed
Muscles are loose, weight is evenly distributed, mouth may be slightly open with a relaxed "smile," eyes are soft, and tail is in a natural position.
Common Contexts:
- Resting at home
- Gentle walks
- After eating or playing
Alert
Body is forward, weight on toes, ears perked up and forward, eyes focused, tail raised but not stiff, mouth closed.
Common Contexts:
- Hearing a strange noise
- Spotting something interesting
- Protective situations
Stressed/Anxious
Body lowered, weight shifted back, ears back or flattened, tail tucked, panting when not hot, yawning, lip licking, avoiding eye contact.
Common Contexts:
- Vet visits
- Loud noises
- Unfamiliar environments
Playful
Front end lowered with rear in the air (play bow), relaxed open mouth, excited tail wagging, bouncing movements, "smiling" expression.
Common Contexts:
- Seeing favorite people/dogs
- Playtime initiation
- With favorite toys
Pro Tip
Always look at the whole picture when interpreting your dog's body language. A single signal (like a wagging tail) can mean different things depending on the context and other body signals present. For more tips on understanding your dog, check out our guide to professional dog training.
What Your Dog's Tail Is Telling You
A dog's tail is one of their most expressive communication tools, but it's often misunderstood. The position, speed, and direction of wagging all convey different messages. Research from the University of Trento shows that dogs wag their tails differently depending on their emotional state.
Tail Positions and Their Meanings
- High and stiff: Alert, confident, or potentially aggressive
- High and wagging: Excited, confident greeting
- Neutral position: Relaxed and content
- Low but not tucked: Unsure or submissive
- Tucked between legs: Fearful, anxious, or stressed
- Wagging to the right: Positive emotions (studies show dogs wag more to the right when seeing someone they like)
- Wagging to the left: Negative emotions or uncertainty
Important
Contrary to popular belief, a wagging tail doesn't always mean a happy dog. A stiff, high wag can indicate agitation or potential aggression. Always consider the tail position along with the rest of the body language. If you're concerned about your dog's behavior, consider our training products or consulting a professional.
Ear Positions and Their Meanings
Dogs' ears are highly mobile and can provide important clues about their emotional state and focus of attention. The ASPCA provides excellent resources on interpreting canine body language.
Common Ear Positions
- Ears forward: Interested, alert, or focused on something
- Ears slightly back: Friendly, social, content
- Ears flattened against head: Fearful, anxious, or submissive
- One ear forward, one back: Uncertain or mildly interested
- Ears twitching or rotating: Listening intently to sounds
Remember that ear positions can vary significantly between breeds. Dogs with floppy ears or cropped ears may show less obvious signals than those with upright, mobile ears.
Understanding Dog Vocalizations
Dogs use a variety of vocalizations to communicate, each with different meanings depending on context, pitch, and duration. According to research published in Scientific Reports, humans can accurately interpret some dog vocalizations better than others.
Barking
Barking serves multiple purposes and can convey different messages based on tone, pitch, and pattern:
- Alert barking: Sharp, repetitive barks - "Something's happening!"
- Play barking: High-pitched, rhythmic barks - "This is fun!"
- Demand barking: Persistent, mid-range barks - "I want something!"
- Fearful barking: High-pitched, sometimes mixed with growls - "I'm scared!"
- Boredom barking: Monotonous, repetitive barks - "I need something to do!"
Whining and Whimpering
Whining typically indicates some form of distress or desire:
- Excitement whining: High-pitched, often with pacing - "I'm so excited!"
- Attention-seeking whining: Persistent, varying pitch - "Notice me!"
- Pain or discomfort whining: Low, consistent - "I don't feel well"
- Stress whining: Accompanied by pacing or panting - "I'm anxious"
Growling
Growling is often misunderstood as purely aggressive, but it serves important communication functions. The American Veterinary Society of Animal Behavior provides guidance on interpreting and responding to growling.
- Play growling: Light, bouncy, accompanied by play bows - "This is fun!"
- Warning growl: Low, rumbling - "Back off" or "I'm uncomfortable"
- Fearful growl: Higher pitched, may show teeth - "I'm scared, stay away"
- Possessive growl: Low, directed at specific object/person - "This is mine"
Important Note
Never punish a dog for growling. Growling is a valuable warning signal that prevents bites. If your dog growls, respect their communication and address the underlying cause rather than suppressing the growl. For help with behavior issues, check our professional training resources.
Howling
Howling is a primal form of communication that serves several purposes:
- Social connection: Responding to other dogs or high-pitched sounds
- Location announcement: "I'm here, where are you?"
- Separation anxiety: Prolonged howling when left alone
- Excitement: Some dogs howl when particularly excited
Recognizing Stress and Anxiety Signals
Understanding when your dog is stressed is crucial for their welfare and for preventing behavior problems. Dogs show stress through subtle body language cues called "calming signals" or "displacement behaviors." The late Dr. Sophia Yin's website has excellent resources on recognizing stress signals.
Common Stress Signals
Yawning
When not tired, yawning can indicate stress, uncertainty, or an attempt to calm themselves or others.
Lip Licking
Quick tongue flicks when no food is present often signal anxiety, stress, or appeasement.
Whale Eye
When a dog turns its head away but keeps its eyes on something, showing the whites of their eyes.
Shaking Off
A full-body shake when not wet can signal a release of tension after a stressful event.
Other stress signals include pacing, panting when not hot, scratching when not itchy, sniffing the ground excessively, and avoiding eye contact. If your dog shows frequent stress signals, consider our calming products or consulting a professional.
Play Signals and Invitations
Dogs have specific signals to indicate they want to play and to ensure play remains friendly and non-threatening. Understanding these signals can help you facilitate positive interactions between dogs.
The Play Bow
The classic play bow (front legs stretched forward, chest low, rear end up) is the most recognizable play signal. It means "I want to play" and also serves as a metacommunication that says "Anything that happens next is just play."
Other Play Signals
- Play barking: High-pitched, excited barks
- Bouncy movements: Exaggerated, springy steps
- Self-handicapping: Larger dogs may roll over or make themselves smaller
- Play face: Relaxed, open mouth that looks like a smile
- Play charging and retreating: Running toward then away from a play partner
How to Improve Communication With Your Dog

- Keep a journal of your observations if helpful
- Learn your individual dog's unique communication style
Be Clear in Your Communication
- Use consistent verbal cues and hand signals
- Keep training sessions positive and reward-based
- Be aware of your own body language and tone of voice
