Care-Tzu
The Care-Tzu is a cross between the Cairn Terrier and the Shih Tzu. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Care-Tzu. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Cairn Terrier
The Cairn Terrier is a small, sturdy working terrier that presents a compact and active appearance well suited to its original purpose of bolting vermin from rocky cairns in the Scottish Highlands. Standing approximately 10 to 11 inches tall at the shoulder and weighing between 13 and 14 pounds, this breed exhibits a body that is medium in length with well-sprung ribs and strong, muscular hindquarters. The overall impression should be of a hardy, workmanlike dog capable of navigating rough terrain while maintaining the agility needed to pursue prey into tight spaces. The head is proportionate to the body with a broad skull that supports a strong, fox-like muzzle of medium length, and the teeth meet in either a scissors or level bite. The Cairn Terrier possesses a distinctive weather-resistant double coat that gives the breed its characteristically shaggy appearance. The outer coat is harsh and wiry in texture while the undercoat remains soft and dense, providing protection from harsh Scottish weather and the damp conditions found in rocky crevices where the breed traditionally worked. Coat colors include wheaten, red, brindle, black, sand, and various shades of gray, though white is not acceptable in the breed standard. The coat naturally appears somewhat unkempt, lending the breed a charmingly scruffy appeal that requires regular but not excessive grooming to maintain. The breed's expression is enhanced by distinctive features including medium-sized, hazel eyes set wide apart and tucked beneath prominent shaggy eyebrows that give the face an inquisitive and alert appearance. The ears are small, pointed, and carried erect, set well apart on the sides of the head. The tail is short and carried high but not curled over the back, completing the outline of an alert and eager little dog always ready for action. The compact feet feature thick pads well suited for scrambling over rocks and rough ground.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament As family companions, Cairn Terriers demonstrate loyalty and affection toward their people while maintaining an independent nature that does not demand constant attention. They generally do well with children who understand how to interact respectfully with dogs and enjoy participating in active play sessions. The breed's natural alert nature makes them excellent watchdogs who will sound the alarm at approaching visitors, though some individuals may develop excessive barking habits without proper training. Their strong digging instinct remains active regardless of their living situation, a behavioral trait deeply ingrained from generations of rooting out prey from underground burrows.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Portosystemic liver shunts represent a potentially serious congenital condition seen in Cairn Terriers where blood vessels bypass the liver rather than flowing through it for normal detoxification processes. Affected dogs may show stunted growth, poor muscle development, behavioral abnormalities, and neurological symptoms. Hypothyroidism, affecting the thyroid gland's hormone production, occurs in the breed and can cause weight gain, lethargy, skin problems, and coat changes. Allergies and skin sensitivities affect some Cairns, manifesting as itching, hot spots, or ear infections that require ongoing management. Regular veterinary checkups, appropriate vaccinations, dental care, and maintaining a healthy weight through proper diet and exercise contribute significantly to the overall health and longevity of these spirited little terriers.
Shih Tzu
The Shih Tzu is a small, sturdy companion dog characterized by its luxurious flowing coat and distinctive flat-faced appearance that has made it one of the most recognizable toy breeds in the world. Standing between 9 and 10.5 inches at the shoulder and weighing from 9 to 16 pounds, this breed presents a compact, solid body that is slightly longer than it is tall. The overall impression should be of a proud, confident little dog with an arrogant carriage befitting its imperial Chinese heritage, where these dogs lived as treasured companions in royal palaces for centuries. The head is round and broad with a warm, sweet expression enhanced by large, dark, round eyes set wide apart. The breed's most striking feature is undoubtedly its magnificent double coat, which consists of a dense, soft undercoat covered by a long, flowing outer coat that can reach the ground when fully grown. The hair is luxurious and silky in texture, growing continuously much like human hair rather than shedding seasonally like most breeds. Coat colors are remarkably varied and all are equally acceptable, including gold, dark brown, light brown, white, gray, black, red, and various combinations such as gold and white, black and white, or tricolor patterns. The distinctive hair on the head is typically tied up in a topknot to keep it from falling into the eyes and interfering with vision. The Shih Tzu's flat face represents a brachycephalic head structure with a short muzzle, broad skull, and undershot bite where the lower jaw extends slightly beyond the upper jaw. The nose is black in most color varieties, though liver-colored dogs may have liver noses, and the nostrils should be broad and open to facilitate breathing. The ears are large and heavily coated, set slightly below the crown of the skull and hanging down close to the head. The tail is set high and carried in a curve well over the back, heavily plumed with long hair that adds to the breed's elegant appearance. Short, sturdy legs with round, well-padded feet complete the compact structure.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament The Shih Tzu generally demonstrates excellent compatibility with children, other dogs, and even cats when properly socialized, though their small size makes supervision important around young children who may inadvertently play too roughly. These dogs possess a confident and dignified demeanor that occasionally manifests as stubbornness when they decide they prefer not to comply with requests. Their low prey drive and gentle disposition make them among the most trustworthy toy breeds around smaller pets and vulnerable family members. Heat sensitivity requires attention, as the breed's flat face impairs their ability to regulate body temperature efficiently, necessitating climate-controlled environments during warm weather.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Patellar luxation affects Shih Tzus at notable rates, causing the kneecap to slip out of position and resulting in intermittent lameness that may require surgical correction in severe cases. Hip dysplasia, though more commonly associated with larger breeds, also occurs in the breed and contributes to arthritis and mobility problems as dogs age. Dental disease represents a particularly prevalent concern in Shih Tzus due to their small mouths and crowded teeth, with many dogs requiring professional cleanings and extractions throughout their lives if adequate home dental care is not maintained. Intervertebral disc disease can affect the breed's relatively long back, causing pain and potentially paralysis. Additionally, the breed's heavy coat and facial folds create environments conducive to skin infections, allergies, and ear problems that require regular cleaning and monitoring. Renal dysplasia, a hereditary kidney condition, has been identified in the breed and can cause kidney failure in affected young dogs.
Important to Remember
Each hybrid dog is unique and may inherit any combination of traits from either parent breed. The information above represents the characteristics of the purebred parent breeds. Your Care-Tzu may favor one parent over the other or display a blend of both. We strongly encourage you to read the complete breed profiles for both the Cairn Terrier and Shih Tzu to fully understand the range of possible temperaments, health concerns, and care requirements.
