Reading Body Language With The Fido Tool: Red, Yellow and Green:

Accurately interpreting a dog’s postures and body language can help people interact safely with the dog, including recognizing when it is safe to even approach, much less attempt to handle a dog.

Body Language: Non fearful dog

Body posture: Relaxed “soft” muscles, weight evenly distributed, “loose” or “wiggly” body

Tail: Relaxed & neutral position, may be wagging Ears: Relaxed, neutral position, orientation

Mouth: Appears “soft”, may be open, tongue out, relaxed muzzle

Eyes: “Soft”, relaxed, eyebrows neutral, normal pupil size, steady relaxed gaze, orientation

Behaviors: non fearful dog

  •  Approach
  • Affiliative behavior
  • Solicits attention
  • Neutral or undisturbed
  • Play bow
  • No/low autonomic arousal
  • Vocalization- none, barking, whining (attention seeking/arousal)
  • Absence of body postures and behaviors indicating fear

Science Says :

Humans often rely on vocalizations and gross body movements to identify a dog’s emotional state (Kerswell et al., 2009) and are frequently accurate in their interpretations of barks (Pongrácz et al., 2005)

Understanding dog body language can help people be better advocates for their dogs, set them up for success in social interactions, and avoid placing them in situations in which they may not cope well and thus, may behave in ways that are undesirable or injurious to themselves and/or others.


Body Language: : Fearful dog

Body posture: Muscles tensed, “hard and stiff”, weight unevenly distributed (forward, back, or to the side), “low and back” or “high and forward”, may be very still, piloerection or blowing coat, may roll over and expose belly or hold up one paw 

Tail: Mid way or low, wagging or still, tucked, carried high, often wagging slowly & methodically, high up over the back with flagging Ears: Pulled back, rotated down, erect and forward, may have little movement or scanning, pulled high with tension (wrinkles) between them 

Mouth: Closed mouth, tension in muzzle, nose wrinkled, tooth display (vertical or horizontal lip retraction) 

Eyes: Wide open, pupils dilated, scanning/ darting, tension (wrinkles) in brow, avert gaze, slow blinking, whale eye, head low/ outstretched neck looking up over brow, “hard stare”, squinted/hooded, eyebrows tensed

Behaviors: Fearful dog

  • No approach
  • Flight- increasing distance 
  • Fight- offensive or defensive aggressive displays
  • Straight hard fast approach- threat
  • Freeze
  • Hiding
  • Catatonic
  • Stereotypies (regularly repeated patterns of behavior with no known function or purpose; e.g., pacing, spinning, wall bouncing)
  • Vocalizations- alarm bark, yelp, scream, growl, none
  • Evidence of stress response
  • Calming signals

From the dog’s perspective, understanding what is being communicated through body language can help them remain safe, preventing dogs from feeling the need to protect themselves by either fighting or fleeing from the interaction.


Body Language: Ambivalent

Body language: so mixed can not categorize as red or green

Body posture: so mixed can not categorize as red or green

Behaviors: Ambivalent

  • Ambivalent approach- both approach and retreat
  • Calming signals with affiliative behaviors and or approach
  • Approach and or attention seeking with fearful body language
  • Partial approach with affiliative behaviors and no fearful body language or behaviors

Calming Signals

Signals used by dogs when they are uncomfortable; intended to keep the calm and avoid/cutoff conflicts- three main categories:

1. Displacement behaviors– normal behavior displaced out of its normal context when an animal is conflicted between two simultaneous drives (e.g. desire to approach & unsure/avoidant) examples: scratching, sniffing the ground, mounting, eating/drinking

2. Appeasement gestures– behaviors meant to reduce potential threat examples: play bow, turn away/ turning head/avert gaze, smiling

3. Stress signs – physical responses used to decrease anxiety and increase information gathering and situation assessment examples: lip/nose licking, yawning, shaking off, darting eyes/head swivels

Important note: Because calming signals by definition indicate that a dog is not entirely comfortable with or sure about the social interaction that is occurring, observing one or more of these behaviors should be interpreted as “proceed with caution.” When calming signals are observed in a dog that is also showing red behaviors, the dog should be considered red. The social interaction should be stopped immediately for safety reasons and to protect the welfare of the dog.

What to Expect From Your Puppy Customer

Knowing what your puppy customer
expects you to ask them is a good way to
know how you should respond when they ask,
“Do you have any questions for our family?”
Adopters expect the breeder to thoroughly
interview them! Some websites demand a
family to find a different breeder if they are
not asked personal questions about their
puppy’s future home. Asking a customer the
right questions can not only prove you are an
ethical breeder but show the customer you
care about your puppy’s long-term success
within an adoption.

How Much Should a Pregnant Dog Weigh?

A pregnant dog should not gain or lose weight in the first five weeks of her pregnancy. Having a scale in the kennel and weighing her once a week is the best way to assure you are providing the proper amount of dog food.
