Raised hackles, the hair on a dog’s back and neck, confuse many pet parents. They may see them as a sign of aggression, but that isn’t always the case. Raised hackles do not qualify as a behavior, as they are an involuntary reflex triggered by something that put the dog into a state of arousal. There is actually a medical term for the reaction: piloerection (pilo referring to “hair” in medical terms).
Raised hackles could be a sign of fear, anxiety, excitement, nervousness or anger. If you notice raised hackles on your dog, you must look at other body language and the context to understand what is happening. Only then can you know how to respond.
Raised hackles as anxiety

My German Shepherd Dog, Ginger, used to display raised hackles every time she met a new dog. I rescued her when she was 7 months old. She hadn’t been properly socialized because she had parvovirus as a pup and needed to be kept away from other dogs until she fully recovered. When she was well enough to finally meet other pups, she was beyond the critical period of puppy socialization and was out of control on the leash, which is why I rescued her.
Meeting new dogs caused her much anxiety, and as an adult that manifested into raised hackles. All of her other body parts conveyed appeasing signals: low horizontal tail wagging, squinty eyes and a paw lift — all with wiggly interest. The good news was that I understood her behavior, and the better news was that dogs we met also read and understood her body language, that she was anxious yet friendly, willing to greet. This image from my Dog Decoder app perfectly represents Ginger in this state.

Ginger got over her initial anxiety within the first 60 seconds of meeting a new dog, and she was the friendliest pup who loved to rough and tumble with the best of them. If I didn’t understand her raised hackles and body language, and saw it as aggression that required her to be removed from the situation, her continued lack of socialization would have caused her to become more anxious and even aggressive, when that wasn’t her original intent.
Raised hackles as excitement
Jack, another pup I worked with in the past, also displayed raised hackles whenever he saw another dog, but because of a different trigger. His was pure and uncontrollable excitement, always wanting to play. He was overly exuberant in his greetings, and oftentimes this put other dogs off from wanting to meet him.
Many dogs displaying this kind of behavior have raised hackles while the rest of their body suggests play: fast horizontal tail wagging, forward ears, even barking and lunging on the leash in excitement. Some might see this as aggressive, too, because of the raised hackles, but for Jack in this situation, it wasn’t at all.
Raised hackles as aggression
In this next image, you’ll see slightly raised hackles at the shoulders and just along the top of the left dog’s back, along with ears back and down, hard eyes, tail high, wide open mouth with teeth showing, and more of a rigid body posture. This combination of raised hackles and body behavior signals aggression from the dog.

Raised hackles as predatory
If a dog is highly aroused, the hair can stand up from their neck all the way to the tip of their tail, as shown in the predatory stalking image below. However, there is no consistent pattern that correlates the amount of hair raised and where to a particular behavior. Each dog and each situation are different.

The bottom line on raised hackles
It’s so important to read your dog’s entire body language and to take context into consideration if raised hackles present. If you don’t, you could create a problem where there wasn’t one before. You could turn a fearful or shy dog into an aggressive one because of how you respond.
The best way to handle a dog with raised hackles is to redirect his attention until you can better understand the triggers and see a pattern. If the reaction persists and escalates, consult a behaviorist who can help you help your dog feel less of whatever triggers them.
Understanding your dog’s body language is crucial to helping our dogs live an emotionally happy and healthy life.
