The Australian Terrier is one of the smallest working terriers — typically 14–16 lbs — developed in Australia in the 19th century from a mix of British terrier breeds (Dandie Dinmont, Skye, Yorkshire, and Cairn Terriers among others). It was the first breed developed and recognized in Australia, bred for ratting, snake control, and companionship in the Australian bush. The Australian Terrier carries the full terrier heritage — bold, tenacious, and strong-jawed relative to its size — which shapes its dental profile.
Australian Terrier Dental Anatomy
The Australian Terrier has a moderately long muzzle typical of terrier breeds:
- Terrier muzzle with good length: The Australian Terrier’s muzzle is longer than brachycephalic small breeds, reducing crowding risk. This working terrier head shape provides reasonable tooth access and spacing compared to toy companion breeds.
- Strong jaw for size: Working terriers were bred for jaw strength. The Australian Terrier’s 14–16 lb frame carries terrier jaw musculature that creates meaningful bite force relative to body weight. Hard chew fracture risk is significant.
- Small teeth with thin enamel: At 14–16 lbs, the Australian Terrier’s teeth have thinner enamel than large breed teeth. Periodontal disease progression is faster than in large dogs, and enamel wears more rapidly.
- Silky topknot: The breed’s distinctive silky topknot and face furnishings can trap food debris around the muzzle. Post-meal facial coat cleaning helps maintain perioral hygiene.
Key Dental Considerations for Australian Terriers
Diabetes Mellitus
Australian Terriers are one of the breeds with notably elevated diabetes mellitus incidence. Diabetes has a bidirectional relationship with periodontal disease: periodontal disease worsens glycemic control, and hyperglycemia impairs periodontal immune response and healing. For diabetic Australian Terriers, daily brushing is not merely cosmetic — it has direct systemic significance. Pre-anesthetic glucose management is essential before dental procedures.
Luxating Patella
Luxating patella is common in small breeds including Australian Terriers. Relevant to anesthetic positioning. Grades III–IV require surgical correction.
Legg-Calvé-Perthes Disease
Legg-Calvé-Perthes disease (femoral head avascular necrosis) is documented in the breed. Typically diagnosed before age 1 and treated surgically. Relevant to anesthetic positioning.
Hypothyroidism
Hypothyroidism is documented in Australian Terriers. Affects metabolic rate and healing. Pre-anesthetic thyroid assessment appropriate for middle-aged and older dogs.
Periodontal Disease at Small Breed Scale
At 14–16 lbs, the Australian Terrier is at elevated periodontal disease risk consistent with small working terrier breeds. The combination of small jaw, thin enamel, and terrier jaw force from chewing creates a dental environment that benefits significantly from consistent preventive care.
Evidence-Based Dental Care for Australian Terriers
Daily Brushing
Daily brushing with VOHC-accepted enzymatic toothpaste from puppyhood. The Australian Terrier’s terrier temperament means early conditioning is important — establishing the dental routine at 8 weeks with treat-reward conditioning. Use a small toothbrush or finger brush appropriate for 14–16 lbs. The longer muzzle than comparable small companion breeds provides reasonable tooth access.
Diabetic Dental Management
For diabetic Australian Terriers, the dental care routine takes on additional systemic significance. Daily brushing reduces oral bacterial load, which helps maintain glycemic stability. Coordinate dental procedure timing with diabetes management — ideally morning procedures allowing full-day glucose monitoring. Inform the veterinary team of all insulin dosing and current glucose readings before dental anesthesia.
Chew Selection
VOHC-accepted small dental chews that yield to thumbnail pressure. No bones, antlers, or hard nylon. Small rubber toys (Kong-type). The terrier jaw force combined with the small size makes hard chew avoidance especially important.
Professional Cleaning
Annual professional cleaning from 1–2 years with full-mouth radiographs. Pre-anesthetic glucose management for diabetic dogs. Thyroid screening for middle-aged and older dogs. Patella and Legg-Calvé-Perthes history for positioning.

Australian Terrier Dental Care Timeline
- 8–10 weeks: Mouth handling conditioning begins; terrier independence means starting early
- 12–16 weeks: Full brushing routine; dental chew introduction
- 5–6 months: Retained deciduous tooth check; patella evaluation
- 1–2 years: First professional cleaning with full-mouth radiographs; diabetes screening baseline; thyroid; patella reassessment
- Annually: Professional cleaning with radiographs; diabetes and thyroid monitoring; orthopedic reassessment
- Daily: Brushing; VOHC small dental chew (pressure-yielding); facial coat wipe; no hard chews
The Australian Terrier is a capable, affectionate companion in a small, spirited package. The diabetes connection makes consistent dental hygiene especially meaningful for this breed — it is one of relatively few breeds where daily tooth brushing has documented systemic health implications beyond periodontal disease alone. Owners who establish the full dental routine early and maintain the discipline give their Australian Terrier the best foundation for oral and systemic health throughout a typical 11–15 year lifespan.
