How Dogs React When Scared: A Dog’s 4 Fear Responses | Pupford
25 Comments Filed under behavior
Fear is an evolutionary response to protect us during life or death situations. When a dog encounters a potentially threatening or anxiety-inducing situation, they will respond with a fear response.
But not all dog’s will respond to fear in the same way. Their response may vary based on genetics, past experiences, and their coping skills learned during their socialization period.
It is essential to understand how dogs display and respond to fear so we can effectively address their emotional well-being.
In this blog post, we will explore the 4 primary fear responses in dogs, also known as the 4 F’s: Fight, Flight, Freeze, and Fidget. By understanding these responses you will have a better understanding of your dog’s behavior and how it may impact your training goals.
Here’s what we’ll cover:
- Fight Response
- Flight Response
- Freeze Response
- Fidget Response
- Combining Responses
FIGHT RESPONSES IN DOGS

The Fight response is one of the most common, and misunderstood fear reactions in dogs. When a dog perceives a threat in their environment, they may react by barking, growling, or lunging as a way to get the threat to move further away from them.
We often see this with reactive dogs who struggle to encounter other dogs when out on walks or who pass by their yard.
It is essential to remember that this reaction isn’t necessarily an indication of an inherently aggressive dog, but a response to fear of a perceived threat.
When working with a dog who is displaying a fight-fear response, it is important to avoid any aversive training methods or the use of punishment. Using these tactics can exacerbate the fear making the response worse. Instead, use positive reinforcement training methods to work on changing the dog’s emotional response to the stimulus that invokes fear.

FLIGHT RESPONSE IN DOGS

The Flight response is another common fear response that you have most likely seen your dog or another dog perform.
When a dog is frightened, they may instinctively try to escape from the perceived threat by quickly moving away. This might look like running away, hiding, or seeking a safe space to retreat.
Dogs will also display body language that indicates fear and appeasement including a tucked tail, low body posture, ears back, whale eyes, lip licking, etc.
Dogs who display this response should not be forced to interact with or be in an environment with whatever they deem threatening. Instead, use counter-conditioning and desensitization techniques to gradually build the dog’s confidence and comfort level in the presence of the fear-inducing stimulus.
FREEZE RESPONSE IN DOGS

The Freeze response is where a dog will remain completely still in the presence of a perceived threat with the hope that it will move past them without noticing them.
Dogs may also exhibit this response when are unsure how to react or if they feel trapped. The dog will likely have tense body language, and avoid making eye contact, with tight lips and their ears back.
Dogs displaying this fear response should not be forced to move as this can exacerbate the fear. Instead, do your best to remove the trigger that is causing them fear, provide them with comfort items, and make changes to their environment that may make it more soothing such as playing white noise.

FIDGET RESPONSE IN DOGS

The Fidget response is a less commonly recognized fear response. When a dog exhibits the fidget response, they display restlessness, nervousness, and often displacement behaviors like excessive scratching, yawning, lip licking, whining, or pacing. These behaviors are a way of coping with the stress and anxiety they are feeling.
It is important to address the fidget response with patience and empathy. Recognize that the dog is experiencing fear, and the fidgeting is a sign of their discomfort.
COMBINING RESPONSES
Sometimes dogs may display a combination of fear responses or transition from one to the other. For example, a dog may initially freeze when confronted with a scary stimulus, but if the opportunity arises to escape, they might transition to a flight response. Or if pushed past their limits and their warning signs are not listened to while fidgeting, they may resort to a fight response if their fear escalates.
Understanding the 4 F’s of fear - fight, flight, freeze, and fidget - is crucial to addressing behavioral concerns and addressing our dog’s emotional well-being. By recognizing these fear reactions we can help our dogs overcome their fears, build confidence, and have a happier relationship with our pups.

Leave a CommentIt has taken a long time and consistency, but my dog (almost 2) is finally not reacting to other dogs on walks. We used the watch me and treat reward. She can now pass a dog while on a walk and not react. She looks at me for a treat. It took over a year. I never thought it was fear- I thought she was just eager to meet other dogs.
Hi Beverley! If she is playing and having fun and not displaying any body language that would indicate she is afraid she is likely not fearful.
Hi Carolyn! This is likely a fight-fear response. I would recommend checking out this article to learn more about alpha dog theories: https://pupford.com/debunking-alpha-dogs/
Hi Lorna! When a dog’s fear response is fight it is not uncommon for them to seek out noises of other dogs when they hear barking or growling
