Factors That Affect Australian Terrier Lifespan

Key factors that affect Australian Terrier lifespan (11–15 years) include:

  • Genetics: Dogs from parents tested for Patellar Luxation and other conditions have better odds of a long life
  • Diet: A balanced diet maintaining 15–20 lbs
  • Exercise: 60+ minutes daily maintains cardiovascular health and healthy weight
  • Veterinary care: Annual checkups with biannual visits after age 9 catch issues early
  • Weight management: Keeping your Australian Terrier lean can add 1-2 years to their life
  • Coat care: Regular maintenance of their rough, straight, harsh outer coat with soft undercoat coat prevents skin issues that can impact overall health
