English Toy Terrier Health and Longevity: What to Know

The English Toy Terrier (black and tan) is a petite, lean little dog from the terrier group. Standing between 10-12 inches tall and weighing just 6-8lb, it is one of the smallest UK native dog breeds. Historically, it was prized as a ratting dog in Victorian England due to its speed and agility.

Only black and tan in colour, the breed's markings are reminiscent of the larger Doberman pinscher. English Toy Terriers are lively, affectionate, and spirited little dogs with a notable tendency to bark loudly.

Regrettably, the English Toy Terrier is now classed as one of the UK’s vulnerable native breeds by the UK Kennel Club. To promote this charming breed and enhance its numbers, the Kennel Club has permitted the closely related toy Manchester Terrier to be registered as an English Toy Terrier, provided the dogs meet the breed standard requirements.

For potential owners, it’s crucial to research thoroughly to decide if this breed suits your lifestyle and to understand its hereditary health and genetic diversity — topics we explore in detail below.

Longevity and Life Expectancy

The average lifespan of the English Toy Terrier is approximately 12 to 13 years, with many living up to 15 years with proper care. This puts the breed in the middle range for longevity among similar toy breeds in the UK. Such life expectancy is supported by responsible ownership, including a balanced diet and regular veterinary care.

Genetic Diversity and Inbreeding

The breed has a coefficient of inbreeding (COI) estimated around 11.1%, which is above the recommended level of 6.25% for pedigree dogs. This elevated COI reflects the breed’s small population size, which can naturally increase genetic similarities. Responsible breeders strive to keep this figure as low as possible within their lines to promote healthier puppies and reduce hereditary issues.

Key Hereditary Health Tests

While generally healthy and robust, the English Toy Terrier is predisposed to certain hereditary conditions that responsible breeders and veterinarians recommend testing for before breeding:

• Von Willebrand’s Disease: A bleeding disorder similar to haemophilia but affecting both sexes. DNA testing helps identify carriers and affected dogs.
• Patellar Luxation: This knee condition causes the kneecap to dislocate or move from its normal position, which can result in lameness or pain. Screening helps manage breeding decisions.
• BAER Testing for Deafness: Brainstem Auditory Evoked Response (BAER) testing screens for hereditary deafness in breed lines.
• Juvenile Dilated Cardiomyopathy (JDCM): A serious hereditary heart condition causing arrhythmias and possible sudden death; DNA screening is available.
• Xanthinuria: A rare metabolic disorder detectable through DNA tests.

Additional Hereditary and Common Health Concerns

Other hereditary or commonly affecting conditions may occur in the breed, often without prior screening tests available. Awareness of health history in parent and grandparent dogs helps reduce risks. These include:

• Demodectic Mange: A skin condition caused by mites leading to hair loss and skin irritation, treatable but with potential to recur.
• Legg-Calve-Perthes Disease: Degeneration of the femoral head in the hip joint resulting in lameness and pain.
• Sensitivity to Heat: Due to their short coat and small size, English Toy Terriers can struggle in hot weather, risking heat stroke.
• Eye Conditions: Including glaucoma, primary lens luxation, and cataracts, which often manifest later in life.
• Dental Issues: Periodontal disease is common, making regular dental care essential.
• Gastrointestinal Problems and Dietary Intolerances: Occasionally reported, necessitating an appropriate diet.

Responsible Ownership and Care

English Toy Terriers thrive with attentive care that includes protection from temperature extremes—coats in winter and cool, shaded environments in summer are important. Regular veterinary check-ups, dental hygiene, and health screening for hereditary conditions ensure better quality of life and longevity.

Choosing a reputable English Toy Terrier breeder who conducts recommended health tests and openly shares health information about their dogs is crucial. This responsible approach helps sustain the breed while reducing the incidence of inherited health issues.

Finding Your English Toy Terrier Puppy

If you are interested in adding an English Toy Terrier to your family, start by ensuring this breed matches your household and lifestyle needs. Consider the dog’s lively nature and specific health sensitivities. Use trusted sources like the UK Kennel Club for guidance and to find English Toy Terrier puppies from reputable breeders.
