The Shairn-Inu is a hybridization of the purebred Shiba Inu and Cairn Terrier.  Typically, the Shairn-Inu is a small dog with a rough coat similar to its Cairn Terrier parent, but the Shiba-Inu parent may give this hybrid more height and weight if its genes are more dominantly represented.  The Sharin-Inu displays Terrier traits including being a vocal dog as well as the Shiba Inu's possessive traits.  This hybrid requires a strong owner who can devote time and energy to training, so the Shirn-Inu is not well-suited to novice dog owners.  However, this hybrid is loyal and affectionate.  They are a remarkably healthy mix and sensitive to their owner's emotions and enjoy a lot of play time with the kids.

Shairn-Inu Breed History

The Shairn-Inu is a rare hybrid between the Shiba-Inu and the Cairn Terrier.  Not much is currently known about the hybrid, and the Shairn-Inu is only recognized by two competitive breed registries, the Designer Breed Registry and the International Designer Canine Registry.  Owners and those who are considering adopting a Shairn-Inu can review the histories, health concerns, and character traits of the parent breeds to get a better idea of the Shairn-Inu. The Shiba-Inu is an ancient dog of Japan that developed alongside the Akita.  The original role of the Shiba-Inu was a hunter that flushed out game animals.  Their name may originate from the brushwood where they hunted, which is Shiba in Japanese or from the red color of the brushwood in autumn.  The Shiba-Inu maintained relative obscurity on the island of Japan and faced near extinction during the bombing raids of World War II.  Following the war, the Shiba-Inu came to America in the 1950s, but the American Kennel Club did not recognize the breed until 1992.  The Cairn Terrier is a member of the Skye Terrier line of Scotland and aptly named for its vermin hunting grounds among the cairns.  The origins of the Cairn Terrier were not clear before its official development in the 19th Century in the Isle of Skye.  The Cairn Terrier was previously classified under the Scotch Terrier group, but fanciers began selecting for specific colors, sizes, and traits during the 1800s, which resulted in breed deviations between the Cairn Terrier, the West Highland Terrier, and the Scottish Terrier.  The Cairn Terrier, similar in appearance to the West Highland Terrier in all but coat color, came to the United States during the late 1800s and early 1900s.  The American Kennel Club officially recognized the breed in 1913, and the most famous Cairn Terrier to date was a little female named Terry who played the part of Toto in the Wizard of Oz.              

Shairn-Inu Breed Appearance

The Shairn-Inu is a small hybrid that retains much of the Terrier appearance.  Their coats are rough and usually rust-colored.  The Shairn-Inu is a compact dog with straight, sturdy legs and a tail that curls over the back, like the Shiba-Inu.  Its ears are set high and triangular-shaped but not large.  The Shairn-Inu's eyes are brown and range in shape from round to oval and have a keen, intelligent expression.  They have round black noses and long muzzles.  The Shairn-Inu's coat color, while mostly red, may come in other colors, such as brindle, brown, or gray, and can have colorful facial and chest markings in cream, brown, or black.

Shairn-Inu Breed Maintenance

Maintaining the Shairn-Inu's coat is easy though they are a moderate shedding dog.  The Cairn Terrier parent may give the Shairn-Inu hypoallergenic qualities as well.  The Shairn-Inu's coat can be maintained with weekly brushing using a bristle or pin brush.  Grooming practices may significantly reduce the amount of dead or loose hair trapped in the coat and may reduce the amount of shedding.  The Shairn-Inu's hair is medium in length but may be longer around the face.  Long hair may trap moisture and dirt but the Shairn-Inu is not a heavy drooling dog, nor does this dog tend to smell.  Both parent breeds have sensitive skin and should only be bathed when necessary.  Frequent bathing may strip the natural oils and cause inflammatory skin conditions for the Shairn-Inu.

Shairn-Inu Temperament

The Shairn-Inu has Terrier qualities, including its stubbornness and tendency for digging or rooting around.  However, they are a sensitive breed and do not tolerate being left alone for long.  The Shairn-Inu is an affectionate dog that loves spending time with its people.  They are also loving toward children and make for excellent playmates.  This hybrid is moderately friendly toward other dogs but may become aggressive if it feels threatened or if it perceives a threat against its people.  The prey-mind of the Shairn-Inu is also acute, and smaller pets, such as cats or hampsters may be chased.  Early and proper socialization will significantly help the Shairn-Inu adjust to living with other pets.  Both parent breeds are considered stubborn, despite their intelligence.  Training a Shairn-Inu requires patience and perseverance, so this breed is not well-suited to novice dog owners or those who do not have a lot of time to devote to their dog's care.

Shairn-Inu Activity Requirements

The Shairn-Inu is an active dog with moderate exercise needs.  They have a high potential for playfulness and enjoy running and jumping.  However, they are a small breed and capable of getting all their exercise needs met while inside but will always welcome an outing for fresh air and exploration of the neighborhood.  The Shairn-Inu has a high tolerance for all weather types but should not be left alone outside or left to run in an unsecured backyard.  Their high intelligence means they need plenty of mental stimulation.  Without proper exercise and mental engagement, the Shairn-Inu may develop negative behaviors, such as digging or chewing.
