The Australian Terrier is classified by The Royal Kennel Club within the smaller ageing band, typically weighing 5–6.5 kg as an adult. One of the first breeds developed in Australia, bred to control rats and snakes on farms, the Australian Terrier is spirited, courageous, and loyal, with a rough, weatherproof double coat.

What this means for your Australian Terrier

Patellar luxation and dental crowding are both relatively common in small terrier breeds, so regular vet checks of the knees and teeth matter throughout its life. Like many terriers, the breed can also be prone to allergic skin conditions, so persistent itching or skin irritation is worth investigating.

Legg-Calvé-Perthes disease, a condition affecting the hip joint in young small-breed dogs, is occasionally seen in the breed — any limping in a young Australian Terrier is worth a prompt vet check.

When is an Australian Terrier considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, small breeds like the Australian Terrier are generally considered senior from around 10 dog years old.
