  1. West Highland White Terrier - Dog Breed
Breed Profile West Highland White Terrier   Petful

The Breed History
The Scottish terrier group all likely arose from the same ancestors (this includes the Scotties, Dandie Dinmonts, Skye, and Cairn terriers). This breed arose in Poltalloch, Scotland perhaps in the times of King James I and may have been previously known as the Dog of Argyleshire. The family of Colonel Malcolm of Poltalloch is considered to have developed the main lineage up through the early 20th century. It may be that the earliest stock was primarily white Cairn in origin. AKC registration was first recorded in 1908.

Breeding for Function
These dogs were originally bred to be vermin, fox and otter hunters; bred for exceptional spunk, speed and intelligence. Sporty and agile, they can work a long day. They are now enjoying success in earthdog trials, obedience and agility. They are excellent companions.

Physical Characteristics
Height at Withers: female 10" (25.5 cm), male 11" (28 cm)
Weight: females 13-16 lb (6-7 kg), males 15-22 lb (7-10 kg).
Coat: Their outer coat is harsh and dense and the undercoat is fine and wooly. They are all white, and the coat is about 2" in length. Longevity: 15 years.
Points of Conformation: The Westie is a compact, short coupled dog, and has well developed musculature. Deep in the chest, they are characterized by a straight topline. Dark brown eyes with dark palpebral margins, small erect ears with thick leather, heavy eyebrows, black nose and lips and a defined stop with blunt muzzle characterize their head. The tail is short and carried high, and incidentally, is tough enough so that the handler can pull the dog out of the burrow by the tail if needed.

Recognized Behavior Issues and Traits
These dogs are reported to be very alert, intelligent, devoted, independent and fun-loving. They thrive on close human contact. They are game to learn, courageous, and are fairly tolerant of strangers. They are high activity dogs. They like to dig and bark especially if bored, and are a good watchdog. As with any of the terrier type breeds, they can nip when irritated and need to be socialized early to other pets and children. Training should be gentle but firm and also start early. The coat should be periodically clipped or stripped to remove dead undercoat hairs.

Inherited Diseases
Hip Dysplasia and Legg-Calve Perthes Disease: Polygenically inherited traits causing degenerative hip joint disease and arthritis. Reported 33.2x odds ratio for Legg-Calve-Perthes versus other breeds. OFA reports 12.4% affected. Legg-Calve Perthes is reported at a frequency of 1.2% in the 2005 WHTCA Health Survey.
Patella Luxation: Polygenically inherited laxity of patellar ligaments, causing luxation, lameness, and later degenerative joint disease. Treat surgically if causing clinical signs. OFA reports 3.8% affected. Reported at a frequency of 6.6% in the 2005 WHTCA Health Survey.
Elbow Dysplasia: Polygenically inherited trait causing elbow arthritis. Reported at a high frequency, however too few West Highland White Terriers have been screened by OFA to determine an accurate frequency.
Craniomandibular Osteopathy (CMO): Autosomal recessive, painful non-neoplastic proliferation of bone on the ramus of the mandible and/or the tympanic bulla. Affected dogs present between 3-10 months of age, with varying degrees of difficulty prehending and chewing food, secondary weight loss and atrophy of the temporal and masseter muscles. In most cases, affected dogs are normal after bony remodeling. Reported 1,313x odds ratio versus other breeds. Reported at a frequency of 0.9% in the 2005 WHTCA Health Survey. No genetic test is available.
Globoid Cell Leukodystrophy (Krabbe Disease): An autosomal recessive lysosomal storage disease causing severe neurological symptoms including seizures, hypotonia, blindness, and death in young affected dogs. Reported at a frequency of 0.6% in the 2005 WHTCA Health Survey. A genetic test is available.
Pyruvate Kinase Deficiency (PK): A rare, autosomal recessive disease of red blood cells causing exercise intolerance with a persistent, severe, and highly regenerative anemia, splenomegaly, and progressive osteosclerosis. A genetic test is available.

Disease Predispositions
Atopic Dermatitis (Allergies): Presents with pruritis (itching) and pyotraumatic dermatitis (hot spots). Reported increased risk versus other breeds in multiple studies. Food allergy was identified in 24% of West Highland White Terriers, and Inhalant allergies were identified in 20% in one study. Reported at a frequency of 31.1% in the 2005 WHTCA Health Survey.
Chronic Interstitial Lung Disease: Progressive respiratory failure, Pulmonary Fibrosis/Bronchiectasis, and Pulmonary Hypertension in West Highland White Terriers is an inherited disorder of aberrant collagen regulation. Affected dogs have chronic cough, dyspnea, and tachypnea over months to years. The mean survival time from onset of clinical signs is 17.9 months. Response to prednisolone, with or without bronchodilators, is variable. Reported at a frequency of 2.8% and an odds ratio of 4.45x versus other breeds.

Persistent Pupillary Membranes: Strands of fetal remnant connecting; iris to iris, cornea, lens, or involving sheets of tissue. The later three forms can impair vision, and dogs affected with these forms should not be bred. Identified in 8.75% of West Highland White Terriers CERF examined by veterinary ophthalmologists between 2000-2005.
Cataracts: A posterior Y suture cataract predominates, with an onset of less than 6 months of age. An autosomal recessive mode of inheritance is suggested. Identified in 8.75% of West Highland White Terriers CERF examined by veterinary ophthalmologists between 2000-2005. Juvenile cataracts are reported at a frequency of 1.8% in the 2005 WHTCA Health Survey. CERF does not recommend breeding any West Highland White Terrier with a cataract.

Keratoconjunctivitis Sicca (KCS, Dry Eye): A familial incidence in the West Highland White has been demonstrated. One study showed one-third of all cases occurring in this breed, with the majority being females between 4 and 7 years of age. Conjunctival hyperaemia and mucus discharge are the primary clinical signs in this breed. Reported at a frequency of 8.4% in the 2005 WHTCA Health Survey. CERF does not recommend breeding any West Highland White Terrier with KCS.

Reported at a frequency of 1.8% in the 2005 WHTCA Health Survey.
Portosystemic Shunt (PSS, Liver Shunt): Abnormal blood vessels connecting the systemic and portal blood flow. Can be intrahepatic extrahepatic or microvascular dysplasia. Causes stunting, abnormal behavior, possible seizures, and secondary ammonium urate urinary calculi. Diagnosis with paired fasted and feeding serum bile acid and/or ammonium levels, and abdominal ultrasound. Reported 6.0x odds ratio versus other breeds. Reported at a frequency of 1.5% in the 2005 WHTCA Health Survey. Undetermined mode of inheritance.
Cystic Calculi (Bladder Stones): West Highland White Terriers are found to have a predisposition to forming bladder stones. Mineral composition is not reported.
Superficial Necrolytic Dermatitis: A metabolic hepatopathy. Increased hepatic catabolism of amino acids is hypothesized to explain the hypoaminoacidaemia seen. Reported with at a higher frequency in the breed. In one report, the median age was 10 years, and 75% were male.
Deafness, Glaucoma, Ichthyosis, IgA Deficiency, Microphthalmia, Oligodontia, Prognathism, Pulmonic Stenosis, and Retained Deciduous Teeth are reported.

Isolated Case Studies
Polycystic Kidney and Liver Disease: Polycystic kidney and liver disease was present in four of six female and three of five male offspring born in two matings between the same pair of West Highland White Terriers. Clinical signs and serum biochemistry analysis consistent with liver failure was evident by 5 weeks of age. Affected pups were euthanized because of their disease. An autosomal recessive mode of inheritance is suggested.
Congenital Angiomatous Cardiac Cysts: Two unrelated male 16 week old West Highland White Terriers presented with acute respiratory distress and heart failure. Postmortum examination showed multiple ventricular cysts, primarily toward the apex, and valvular malformation.
Necrotizing Encephalitis: A 2 year old male West Highland White Terrier presented with seizures, depressed mentation, proprioceptive deficits and a decreased menace response. Post-mortum examination showed cerebral non-suppurative inflammation and large areas of cavitation, as well as anti-glomerular basement membrane positive glomerulonephritis.
L-2-Hydroxyglutaric Aciduria: A 5 year old male West Highland White Terrier presented with seizures, moderate four limb ataxia, impaired vision, dementia, and recent episodes of severe head tremor when stressed. MRI demonstrated bilaterally symmetrical polioencephalopathy. Biochemical testing showed L-2-hydroxyglutaric aciduria.
Ectrodactyly: A case of monomelic forelimb ectrodactyly (lobster-claw deformity) in a West Highland white terrier is reported. The dog was treated with a soft tissue reconstruction. This was the second report of ectrodactyly in this breed.
