Fear aggression is characterized by rapid nips or bites because a fearful dog is motivated to bite and then run away. Sometimes the aggression doesn't begin with clear threats. A fearful dog might not show her teeth or growl to warn the victim off.
Dogs that are fear aggressive will often adopt body postures that signal fear while retreating, such as cowering, lip licking and baring teeth. If your dog is cornered or has nowhere to run, she might growl, lunge, snap or bite in an attempt to get the threat to move away.
Fear- and anxiety-related aggression are commonly manifested in the veterinary hospital or in situations of social approach and handling. Dogs that display aggression are not mean or bad dogs. They are simply afraid/fearful and anxious/nervous about a perceived or anticipated threat or unpleasant outcome.
Signs of fear that may happen before aggressive behaviors in dogs could include: Specific body language cues. These cues include a lowered or tucked tail, ears pulled back, wide eyes with large pupils (“whale eye”), wrinkled brow, tense face or body, crouched positioning or making themselves small.
While dog aggression can never be fully “cured,” there are many ways to help manage the condition and help your dog overcome their fears. While their fear and aggression may never fully go away, the fears and behaviors can be reduced with proper training.
Aggressive dogs try to look large and threatening. Fearful dogs try to look small and invisible. A scared dog will usually: Tuck his tail instead of standing straight and rigid.
The signs of a dominant and aggressive dog include staring; excessive low-range barking; snarling; growling and snapping; standing tall; holding ears erect; and/or carrying tail high and moving it stiffly from side to side. However, beware, often a dominant aggressive dog will give no sign before biting.
"Fear or anxiety related aggression is perhaps the most common form of aggression in dogs." Early manifestations of fear related aggression are typically defensive, displayed to increase the distance between the perceived threat, or communicate 'stay away', yet aggression may become more offensive through learning.
Fear and anxiety can take a long time to resolve, and in some cases may never fully resolve (even if great progress is made). So it's important to understand that it may take a long time to help your pet, and that fearful dogs can still have a happy life. And it's important to celebrate the successes along the way.
Most scientific studies indicate that it is very possible to rehabilitate a dog after they bite another dog or person.
A fearful dog may lean away, lean back, tremble, crouch, lower his body or head, or roll onto his side or back. Often, his eyes will often be fully open with large pupils, his forehead will be wrinkled, and his tail will be lowered or tucked.
Sure, they don't like that we're yelling, but do they actually know that we're upset? Well, according to science, the answer is actually yes! Depending on the behaviors we exhibit when we're mad, dogs will recognize them and react differently.
There are two major fear periods in a puppy's socialization. One is at 8-11 weeks and the other is 6-14 months. These fear periods are evolutionarily programmed and are protective for dogs in the wild. Even though dogs live as pets now, these genetically determined behavioral patterns are still present.
a form of aggression in which an animal attacks after it has been severely threatened or cornered.
LEVEL 3—A SINGLE BITE WITH SHALLOW WOUNDS
Whatever the reason for a Level 3 bite, whether rough play that escalates, fear, poor socialization, or something else, this level of aggression must be dealt with. The dog should be taken to a vet or trainer as soon as possible.
Ignore him for 30 to 60 seconds. If your dog follows you or continues to bite and nip at you, leave the room for 30 to 60 seconds. (Be sure that the room is “dog-proofed” before you leave your dog alone in it. Don't leave him in an area with things he might destroy or things that might hurt him.)
Stop it or remove your dog from the situation before it escalates. Do not discipline your dog with physical, violent, or aggressive punishments. Opt for positive reinforcement before resorting to the use of aversives. Remember to reward your dog for good behavior.
But if you have a dog going through their first year of life, the most common ages where we see the signs of a fear period are between 8-11 weeks of age, and between 6-14 months of age. Both periods can be expected to last between 2-3 weeks.
Not only does comfort not reinforce fear, we have evidence that our dogs benefit from our comfort and support by showing reductions in stress and anxiety. Be there for your dog, always.
Resource Guarding Aggression
While it appears not to be a fear-based aggression, it is arguable that the dog is fearful of losing a valued resource, thus making it fear-based in actuality. A sub-type of this type of aggression is distance resource guarding.
