Old English Sheepdog Weight & Growth Chart
Complete weight guide with growth charts for male and female Old English Sheepdogs from puppy to adult.
The Old English Sheepdog belongs to the Herding group and originates from England. Adults typically weigh between 60 and 100 pounds, standing 21 to 22 inches at the shoulder. Life expectancy runs from 10 to 12 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 $204 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.
Old English Sheepdog Weight Overview
Males weigh 60 to 100 pounds, females 60 to 85 pounds. They should appear square and muscular under their profuse coat. Regular grooming sessions help monitor body condition hidden beneath the fur.. Males tend to be larger at 60–100 lbs versus 51–88 lbs for females.
Genetics, diet, and exercise all play a role in determining your dog's ideal weight. The growth chart below provides a general timeline for weight gain from puppyhood through adulthood.

When Does a Old English Sheepdog Stop Growing?
Expect your Old English Sheepdog to reach adult height of 21–22 inches by 15–24 months. Full body maturity, including muscle development toward the 60–100 lb target, may continue until 18–30 months.
Growth is influenced by genetics, nutrition quality, and spay/neuter timing. Hip dysplasia and eye diseases are the primary concerns. Autoimmune thyroid disease is more common in this breed than many others. Regular health screening is essential for breeding stock..
Old English Sheepdog Male vs Female Size Differences
Male and female Old English Sheepdogs differ noticeably in size, a pattern common in large breeds. Males typically weigh 60–100 lbs, while females weigh 51–88 lbs. Both sexes stand 21–22 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 Old English Sheepdogs 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 Old English Sheepdog Overweight?
Assessing your Old English Sheepdog's body condition (healthy range: 60–100 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 Old English Sheepdogs face higher risks of Hip Dysplasia, joint problems, and shortened lifespan. As a large-sized herding breed, maintaining lean body condition is especially important for longevity. Work with your vet to adjust feeding and exercise if needed.
Old English Sheepdog Weight Management Tips
Maintaining your Old English Sheepdog at a healthy weight between 60 and 100 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 Old English Sheepdog'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 Old English Sheepdog 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 Old English Sheepdog 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 Old English Sheepdog: 0.9–2.0 cups of high-quality dry food in two meals, budgeting $80–120/month. Puppies growing toward 60–100 lbs need three to four daily feedings until around six months old. Hip dysplasia and eye diseases are the primary concerns. Autoimmune thyroid disease is more common in this breed than many others. Regular health screening is essential for breeding stock., treats count toward daily calorie intake.

The following table shows expected weight ranges for male and female Old English Sheepdogs at key developmental milestones.

| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 18.0–22.0 | 15.3–18.7 |

Health Risks of Incorrect Weight in Old English Sheepdogs
Both underweight and overweight conditions pose serious health risks for the Old English Sheepdog. Understanding these risks reinforces the importance of maintaining your dog within the 60–100 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Hip Dysplasia. Overweight Old English Sheepdogs 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 Old English Sheepdog consistently below 60 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 Old English Sheepdog appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
