THE INVOLUNTARY MOHAWK
Technically called Piloerection – when the fur on a dog’s back area stands on end.
Piloerection in dogs is an involuntary response – not within conscious control. It’s usually linked to feeling a strong emotion and could be compared to a person getting goosebumps.
It’s far easier to see in short haired dogs than those with a longer coat.
A breed like the Rhodesian Ridgeback has a clear distinctive ridge of fur on their back. This is formed by a selected gene mutation which causes that particular fur to grow in the opposite direction from the rest. This ridge is standard for this breed and is not related to an emotional state.
Piloerection is commonly thought only to be seen in reactive or aggressive dogs, but that’s not always the case.
Dogs that are feeling aroused, excited, fearful, startled, stimulated, conflicted or insecure in some way, also exhibit this.
As with all behaviour, it’s important to look at the context, in conjunction with other body language, the environment and specific situation in order to establish the cause and decide on the best way to intervene if necessary.
Dr Karen London - an ethologist and highly qualified behaviourist, trained in observing animals and behaviour, has made some very interesting observations about different patterns of raised fur being linked to different emotional states.
In Dr London’s professional opinion -
A thin patch of fur all along the back to the base of the tail is associated with a high level of confidence. These dogs are more likely to be on the offensive and react more aggressively.
A thick patch across shoulders to around ¼ way down the back is associated with a low level of confidence and is seen in dogs that are more fearful.
A patch of fur raised at the shoulders and another patch at the base of the tail – the fur in between is not raised, is associated with dogs that are conflicted and unsure of how to react. These dogs may be unpredictable and more likely to be reactive.
Dr London states that there are many exceptions, but in general, this applies to the majority of dogs that she observes.
