Australian Terrier Weight & Growth Chart
Complete weight guide with growth charts for male and female Australian Terriers from puppy to adult.
The Australian Terrier belongs to the Terrier group and originates from Australia. Adults typically weigh between 15 and 20 pounds, standing 10 to 11 inches at the shoulder. Life expectancy runs from 11 to 15 years, and the figures on this page describe that range rather than a single average, because the spread is what matters when you are deciding. Running costs settle around $103 a month once the dog is past puppyhood, before insurance and before anything unexpected. These numbers come from published breed standards and, where a standard is silent, from longevity and veterinary studies; they describe the breed as a population and not the dog in front of you. Line, upbringing, early socialisation and simple chance move an individual well away from the typical profile, and two dogs of the same breed often differ more than two dogs of different breeds. Nothing here is a diagnosis: for a specific animal, a veterinary surgeon who has examined it will always know more than a table.
Australian Terrier Weight Overview
Adult Australian Terriers typically weigh between 15 and 20 pounds, with males generally being larger than females. Males average 15–20 lbs while females typically weigh 12–17 lbs.
Small and compact at 15 to 20 pounds and 10 to 11 inches tall, they are low-set and slightly longer than they are tall..

When Does a Australian Terrier Stop Growing?
Expect your Australian Terrier to reach adult height of 10–11 inches by 12–15 months. Full body maturity, including muscle development toward the 15–20 lb target, may continue until 14–18 months.
Growth is influenced by genetics, nutrition quality, and spay/neuter timing. Diabetes is more common in Australian Terriers than most breeds, making regular glucose monitoring and weight management particularly important for the breed..
Australian Terrier Male vs Female Size Differences
Male and female Australian Terriers differ noticeably in size, a pattern common in small breeds. Males typically weigh 15–20 lbs, while females weigh 12–17 lbs. Both sexes stand 10–11 inches tall at the shoulder, though males tend to fall at the upper end of this range.
These size differences can influence practical ownership decisions. Larger males require more food, larger crate sizes, and stronger leash handling. Female Australian Terriers at the lower weight range may be easier to manage physically for smaller handlers or families with children. Both sexes share the same temperament and health profile, so size preference should be a practical decision rather than a temperament-based one.
Is My Australian Terrier Overweight?
Assessing your Australian Terrier's body condition (healthy range: 15–20 lbs):
- Rib check: Run your hands along the ribcage, you should feel individual ribs under a slight fat layer
- Overhead view: A defined waist should be visible between ribs and hips
- Side profile: The abdomen should tuck upward behind the last rib
Overweight Australian Terriers face higher risks of Patellar Luxation, joint problems, and shortened lifespan. Even for a small-sized breed, excess weight significantly impacts joint health and overall wellbeing. Work with your vet to adjust feeding and exercise if needed.
Australian Terrier Weight Management Tips
Maintaining your Australian Terrier at a healthy weight between 15 and 20 lbs is one of the most impactful things you can do for their long-term health. Studies consistently show that lean dogs live an average of 1.8–2.5 years longer than overweight dogs of the same breed.
Portion control: Use a measuring cup for every meal rather than estimating. Feed the amount recommended for your Australian Terrier's ideal weight, not their current weight if they are overweight. Divide daily food into two meals for adults and three meals for puppies under six months.
Treat management: Treats should not exceed 10% of daily caloric intake. Use small, low-calorie training treats and consider using pieces of your dog's regular kibble as rewards during training sessions. Avoid table scraps entirely, as they add unpredictable calories and can introduce foods that are toxic to dogs.
Exercise alignment: With an exercise needs rating of 3/5, the Australian Terrier requires moderate daily exercise. Balance food intake with activity level, adjusting portions during periods of reduced activity such as recovery from illness or injury.
Regular weigh-ins: Weigh your Australian Terrier monthly and track the trend. Gradual weight gain of even one to two pounds per month can lead to significant obesity over time. Your veterinarian can establish your dog's ideal weight during wellness visits and recommend caloric adjustments as needed.
Feeding Recommendation
Daily food for an adult Australian Terrier: 0.5–0.4 cups of high-quality dry food in two meals, budgeting $40–64/month. Puppies growing toward 15–20 lbs need three to four daily feedings until around six months old. Diabetes is more common in Australian Terriers than most breeds, making regular glucose monitoring and weight management particularly important for the breed., treats count toward daily calorie intake.
Australian Terrier Weight by Age Table
The following table shows expected weight ranges for male and female Australian Terriers at key developmental milestones. Individual dogs may fall slightly outside these ranges depending on genetics, nutrition, and activity level. Consult your veterinarian if your Australian Terrier's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 4.6–5.4 | 3.9–4.6 |
| 6 months | 10.0–12.0 | 8.5–10.2 |
| 9 months | 14.6–17.4 | 12.4–14.8 |
| 12 months | 18.2–21.8 | 15.5–18.5 |
Health Risks of Incorrect Weight in Australian Terriers
Both underweight and overweight conditions pose serious health risks for the Australian Terrier. Understanding these risks reinforces the importance of maintaining your dog within the 15–20 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Patellar Luxation. Overweight Australian Terriers also face higher rates of diabetes, heart disease, respiratory compromise, heat intolerance, and reduced lifespan. Even moderate excess weight, just 10–15% above ideal, shortens life expectancy and reduces quality of life.
Underweight risks: A Australian Terrier consistently below 15 lbs may be experiencing inadequate nutrition, parasitic infection, dental problems that prevent eating, or underlying illness. Underweight dogs have weakened immune systems, poor coat quality, reduced energy, and slower healing. If your Australian Terrier appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
