Can Shiba Inus Uncurl Their Tails?

Shiba Inus can uncurl their tails, especially when they fall asleep. If you’re keen, when your Shiba Inus is asleep, they often have the tail cover the facial region.

So, the tail remains curled for almost their entire lifetime. There is often no need to uncurl their tails as it was meant to serve their purposes when curled.

That said, don’t expect the Shiba Inu tail to uncurl like that of other dogs. Even in fear, the Shiba Inus tail usually remains curled but goes slightly between the hind legs.

Unlike Shiba Inus, other dogs have their entire tail go between the hind legs when they’re in fear. This isn’t the case for Shiba Inu.

While still young, Shiba Inus can uncurl their tails and even spend time with the tail in a straight position.

However, as they age, Shibas lose the ability to uncurl their tail completely. So, the only remaining time they uncurl the tail is sleeping.

Which Is the Standard Shiba Inu Tail Curl?

The standard and preferable Shiba Inu tail curl is the single curl. It manifests as a curled tail with a powerful and dignified tail vertebra.

In addition, the hair around and on the tail area should be more than in other body parts. The tail should have slightly longer hair.

If your Shiba is among the ones with an extended tail, it should reach the hocks. The tail can curl in both directions.

I’ve come across people worrying about the side their Shiba Inu tail curls, and always happy to let them know there’s no standard side toward which their Shibas tail should curl towards.

However, most Shibas have their tails curling to the left; thus, most people call it the standard curl.

The Shiba Inu single curling tail should be relaxed and not stiff. Also, it should be flexible and wag a little bit with a fluid curve.

Researchers argue that the curling Shiba Inu tail and its position give the breed enough body balance and ease morbidity.

When on the chase, Shibas needed a body balance to maneuver in bushy areas. Therefore, a curling tail prevents injuries, especially during hunting.

The tail also has an aesthetic purpose, portraying the Shibas curling crown of confidence. It also portrays the breed as a confident and fierce one.

That said, watch out for Shibas with a thin tail that has no longer hair than the body areas. Do this primarily when searching for an adult Shib to adopt in shelters.

Shiba Inus with a weak tail without longer fur or the curl is considered a severe fault. So, Shibas without a hairy tails are hardly accepted in dog show rings.
