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 CommentMy male cavapoo is 15 months old. From a very young age when out on a walk, he has gotten down on the floor and refused to move when he sees another dog either behind him or coming toward him. Sometimes he does it when he sees a human. We thought he was wanting to play, is this the freeze response. He doesn’t get aggressive or try to run away. When the dog has passed by, he starts going berserk and jumping up at us, or grabbing our shoe laces, barking and it takes a good five minutes to calm him down. Should we be treating this as fear rather than being stubborn and wanting to play with the other dog?
Hi Jennifer, I am sorry to hear that. That sounds frustrating for both you and your pup. I would look into cooperative care handling: https://pupford.com/cooperative-care-dog-training/
Hi Wendy! This could very well be a fear response. I would look closely at his body language when he does this.
Hi Michelle! The majority of dogs are actually dog-selective, which means they like some dogs and not others, so it is not unusual that she reacts to some dogs but not others. It can be helpful to keep track to see if there are any sort of patterns. Does she not like big dogs? Fluffy dogs? Is she more likely to react if they are really energetic? etc. I would recommend going to the CCPDT website, you can search for trainers in your area by zip code and they will all use positive reinforcement-based training methods.
My rescue dog either lunges towards or tries to run away from other dogs. I’m positive this is fear. But yesterday, we were within hearing but not seeing distance of a dog fight (about 1/2 a block away) and my dog got agitated and started pulling me toward the fight. Could this be aggression or was he trying to scare the dogs that he couldn’t even see away?
