Fear Aggression
What is Fear Aggression in Dogs?
Fear aggression in dogs is fairly common and often misunderstood. Fear aggression is directed towards a person or another animal and the motivation is to display aggressive signals (showing teeth, growling, lunging or even making contact and biting) in an attempt to move that dog or person AWAY. Fear aggression rarely comes out of the nowhere and frequently there are subtle warning signs that happen well before the big obvious ones like growling and lunging.
Flee, Fight or Freeze
When a fearful dog feels threatened or unsafe the best option is for them to move away. If the option to move away (flee) isn’t there or the dog learns that moving away doesn’t work (i.e. your uncle who keeps pursuing your nervous dog in an attempt to “make friends”) then the dog may turn to more a proactive means to protect himself, by moving towards the threat and showing teeth, growling, lunging or biting (fight). The third option a fearful dog has is to just hold very still and “tolerate” the intrusion into his space in the hopes that the threat will just go away (freeze). Often the freeze is misinterpreted as the dog being “OK” when in reality the dog is really not OK at all.
Fear aggression is often a combination of genetic and environmental factors, it can also be the direct result of a traumatic experience. For some dogs just one extremely negative experience is all that is necessary to open the door to long-term behavior fallout.
What are the Signs of Fear Aggression?
Dogs that are fear aggressive often start at the low end of the aggression ladder.
Every dog is different, but the common signs of discomfort include:
- actively moving away from people or dogs who are approaching
- hiding behind your legs
- lip licking
- a dog making himself small (cowering)
- tucked tail
These signs may be even be present in young dogs or puppies.
If your dog is uncomfortable and then feels cornered or trapped, he may escalate up the aggression ladder to the growl, lunge, snap or bite in an attempt to get the threat to move away.
It is also not uncommon for a dog with fear aggression to retreat from, freeze or even “tolerate” an interaction but then lunge, nip or bite at the person from behind as they walk away.


How We Can Help
- We will start by assessing the WHY behind your dog’s fear aggression. When you understand the WHY, you are in a much better position to know HOW to help your dog keep calm.
- We will clearly identify all of your dog’s triggers and help you understand the trigger hierarchy as well as the effects of trigger stacking.
- Look at all the places your dog is experiencing aggression and behaving in an emotionally unregulated way so we can address all areas of problem behavior.
- Teach the human end of the leash so you can avoid the big mistakes the owners of fear aggressive dogs often make. I.E. you may have read or been told to have your friends, family and neighbors feed treats to your dog who is fearful of people he does not know. We will explain why this is counter-productive and help you avoid other strategies that may make the training process take much longer.
- Teach you and your dog the strategies and skills you need to counter the aggressive behavior while out on walks or when entertaining guests in your home.
- Help your dog (and you!) relax in the presence of the things that cause the fear aggression so you can reduce all the stress and enjoy time with your dog.
