Body Language


Dogs are incredibly perceptive when it comes to reading human body language. They can pick up on subtle cues in your posture that indicate your mood or intentions. If you’re feeling confident and relaxed, your posture may be upright with your shoulders back. On the other hand, if you’re feeling anxious or scared, your posture may be more hunched over, with your head and shoulders rounded forward.

Facial expressions:

Your facial expressions can also give away a lot about your emotions. Dogs are experts at reading human faces and can easily detect when you’re happy, sad, angry, or fearful. A smile and bright eyes can indicate happiness, while a furrowed brow and downturned mouth may suggest sadness or worry.


Dogs pay close attention to our gestures and movements, as they can provide valuable information about our intentions and emotions. For example, if you make a sudden, jerky movement, your dog may perceive it as a threat or cause for concern. On the other hand, if you have open, relaxed movements, your dog is more likely to feel at ease and comfortable in your presence.



Dogs have a remarkable ability to sense fear in humans. They are incredibly attuned to our emotions and can pick up on subtle changes in our behavior and body language. If you’re feeling fearful, your dog may respond by cowering, hiding, or displaying signs of distress. They may also become more protective or attempt to comfort you during times of fear.


When you’re feeling sad, your body produces different chemical signals that dogs can detect. They may become more gentle and affectionate, offering comfort and solace during your moments of sadness. Dogs can even sense tears and respond by licking your face or snuggling up next to you, providing emotional support when you need it the most.


Anxiety can be detected by dogs through a combination of body language and chemical signals. Dogs are highly sensitive to changes in your breathing patterns, heart rate, and perspiration levels, all of which can indicate anxiety. They may also pick up on behavioral cues, such as restlessness, pacing, or excessive licking, to identify when you’re feeling anxious.


When you’re happy, your body language and energy levels change in ways that dogs can easily detect. Your posture may become more relaxed, and you may exude a sense of calmness and contentment. Dogs often mirror our emotions, so if you’re feeling joyful and upbeat, they are likely to join in on the positive energy, wagging their tails and showing enthusiasm.


Dogs are keen observers of human anger and can sense when we’re feeling upset or angry. They may pick up on changes in your vocal tone, body tension, and facial expressions that indicate anger. In response, dogs may become more cautious or submissive, sensing that you’re in a negative emotional state. It’s important to remember to remain calm and in control of your emotions when interacting with your dog to avoid triggering fear or aggression.

Stress Levels


Cortisol is a stress hormone that is released in response to various triggers, such as perceived threats or stressful situations. Dogs have the ability to detect changes in your cortisol levels through their remarkable sense of smell. When you’re stressed, your body releases different chemicals, including cortisol, which can be detected by dogs. They may respond by becoming more alert or trying to comfort you during times of stress.

Heart rate:

A person’s heart rate increases when they’re under stress or feeling anxious. Dogs can perceive these subtle changes in your heart rate through their acute sense of hearing. They may become more attentive, vigilant, or even attempt to soothe you when they sense that your heart rate is elevated. Your dog’s presence alone can have a calming effect, helping to lower your heart rate and reduce stress.

Physical Health

Body temperature:

Dogs have an extraordinary ability to detect changes in body temperature. When you’re unwell, your body temperature may deviate from the norm, and dogs can sense these variations through their sense of touch. They may lay their head on your lap or snuggle closer to provide warmth and comfort when they sense that your body temperature is abnormal. This can be especially helpful when you’re running a fever or experiencing chills.


Dogs have been known to detect certain illnesses, such as cancer, through their highly developed sense of smell. They can detect the odor of specific compounds released by cancer cells, which may lead to changes in their behavior towards an affected individual. Additionally, dogs can sometimes sense sickness or discomfort simply through observing changes in your behavior, such as decreased energy levels or a lack of appetite.

Breathing patterns:

Changes in your breathing patterns can indicate different states of physical and emotional well-being. When you’re unwell or experiencing discomfort, your breathing may become shallow or irregular. Dogs can pick up on these changes and may respond by staying close to you, providing comfort, or even alerting you to potential health issues.


Dogs have an innate ability to sense pain and injury in humans. They may carefully approach an injured individual, sniffing and inspecting the affected area, as if trying to assess the extent of the injury. Their presence and gentle touch can provide comfort and reassurance during times of physical pain or injury.

If you’re feeling withdrawn or emotionally distant, dogs can sense these changes in your behavior.

Dogs have been shown to alleviate symptoms of depression by providing companionship, motivation for physical activity, and a sense of purpose, contributing to overall well-being.


Anxiety can be sensed by dogs through a combination of visual and olfactory cues.
