PetPALS Dog Behaviors

Dog Behaviors

Dogs have a complex system for communicating. They communicate through vocalizations, smells and scents, body language, and direct contact. Below are some examples of different behaviors dogs display when they communicate with people, other dogs, and other animals. A dog does not express all of these behaviors in each situation. Remember to observe the complete picture within the dog’s environment when interpreting these behaviors. Variations between individual dogs, as well as between breeds, must be considered when interpreting behaviors.

Relaxed Posture

relaxed dogA relaxed dog displays a natural body posture. This dog is not worried or threatened by what is going on in his immediate surroundings. He is content and reasonably happy. Knowing what a dog looks and acts like when he displays this posture serves as a foundation for determining his other behaviors.

  • Eyes relaxed and slowly blinking
  • Ears pricked (up) but not forward, or relaxed slightly down and back
  • Mouth loose, corners relaxed, mouth may be slightly open
  • Tongue may be slightly visible or hanging over lower teeth
  • Soft muscle tone
  • Weight evenly distributed on all four feet
  • Tail down and even, may show relaxed sweeping back and forth
Alert Posture

  • Eyes open wide, alert eye contact (however, this may signal aggression from a strange dog)
  • Ears pricked and forward, may move back and forth
  • Mouth closed
  • Tail pointing away from dog, almost horizontal, not stiff or bristled

Playful or Play Bow Posture

Aggressive-Fearful Dog or Defensive Threat Posture

defensive dogBe very concerned about dogs in defensive threat posture. These dogs are showing signs of fear or submission and aggression. Dogs displaying this behavior are afraid and may attack if pushed. This is the posture assumed by fear-biters, dogs who bite out of fear. People often read them wrong, thinking they are harmless because most of their facial expressions show signs of submission. They do not look beyond the facial expression to the rest of the dog’s posture to see what he is really communicating. Defensive threat is the most dangerous body posture of dogs.

  • Ears flattened back against head
  • Direct eye contact, fixed stare
  • Eyes large and round, dilated pupils
  • Corners of mouth drawn back, lips slightly curled (similar to submissive grin)
  • May slightly expose teeth
  • Nose wrinkled
  • Weight shifts to hind feet
  • Body lowered, crouching position
  • Hackles on neck and back raised
  • Tail tucked, may slightly wag
  • Growls, raises and lowers pitch
