Australian Shepherd Weight & Growth Chart
Complete weight guide with growth charts for male and female Australian Shepherds from puppy to adult.
The Australian Shepherd belongs to the Herding group and originates from United States. Adults typically weigh between 40 and 65 pounds, standing 18 to 23 inches at the shoulder. Life expectancy runs from 12 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 $176 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 Shepherd Weight Overview
Adult Australian Shepherds typically weigh between 40 and 65 pounds, with males generally being larger than females. Males average 40–65 lbs while females typically weigh 34–57 lbs.
Males weigh 50 to 65 pounds, females 40 to 55 pounds. Working-line dogs tend to be lighter and more agile than show lines. They should appear athletic and well-muscled without being bulky..

When Does a Australian Shepherd Stop Growing?
The Australian Shepherd stops growing in height (target: 18–23 inches) around 12–15 months of age, but may continue adding weight toward 65 lbs for a few more months. Males weigh 50 to 65 pounds, females 40 to 55 pounds. Working-line dogs tend to be lighter and more agile than show lines. They should appear athletic and well-muscled without being bulky..
Their double coat, medium length, weather-resistant coat may also undergo changes during this period, reaching its adult texture by maturity.
Australian Shepherd Male vs Female Size Differences
Male and female Australian Shepherds differ noticeably in size, a pattern common in medium breeds. Males typically weigh 40–65 lbs, while females weigh 34–57 lbs. Both sexes stand 18–23 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 Shepherds 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 Shepherd Overweight?
Assessing your Australian Shepherd's body condition (healthy range: 40–65 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 Shepherds face higher risks of Hip Dysplasia, joint problems, and shortened lifespan. Even for a medium-sized breed, excess weight significantly impacts joint health and overall wellbeing. Work with your vet to adjust feeding and exercise if needed.
Australian Shepherd Weight Management Tips
Maintaining your Australian Shepherd at a healthy weight between 40 and 65 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 Shepherd'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 5/5, the Australian Shepherd requires vigorous daily activity. Insufficient exercise paired with full feeding portions guarantees weight gain. Ensure at least 60 minutes of activity daily, combining walks with active play sessions.
Regular weigh-ins: Weigh your Australian Shepherd 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
Feed an adult Australian Shepherd approximately 0.6–1.3 cups of quality kibble daily, split into two meals. Males (40–65 lbs) may need slightly more than females (34–57 lbs). Males weigh 50 to 65 pounds, females 40 to 55 pounds. Working-line dogs tend to be lighter and more agile than show lines. They should appear athletic and well-muscled without being bulky.. Active individuals with energy rated 5/5 may need portions at the higher end of guidelines.
Australian Shepherd Weight by Age Table
The following table shows expected weight ranges for male and female Australian Shepherds 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 Shepherd's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 14.6–17.9 | 12.4–15.2 |
| 6 months | 32.2–39.3 | 27.3–33.5 |
| 9 months | 46.8–57.2 | 39.7–48.7 |
| 12 months | 58.5–71.4 | 49.7–60.8 |
Health Risks of Incorrect Weight in Australian Shepherds
Both underweight and overweight conditions pose serious health risks for the Australian Shepherd. Understanding these risks reinforces the importance of maintaining your dog within the 40–65 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Hip Dysplasia. Overweight Australian Shepherds 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 Shepherd consistently below 40 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 Shepherd appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
