Whippet Weight & Growth Chart
Complete weight guide with growth charts for male and female Whippets from puppy to adult.
The Whippet belongs to the Hound group and originates from England. Adults typically weigh between 25 and 40 pounds, standing 18 to 22 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 $126 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.
Whippet Weight Overview
A fully grown Whippet weighs between 25 and 40 pounds. Males range 25–40 lbs; females 21–35 lbs.
Weighs 25 to 40 pounds with a lean, muscular build; any visible ribs are normal and not a sign of being underweight..

When Does a Whippet Stop Growing?
Most Whippets reach adult height of 18–22 inches by 12–15 months, with full body weight of 25–40 lbs achieved shortly after. Males fill out to 40 lbs while females reach 35 lbs.
Growth rate is influenced by genetics, diet quality, and spay/neuter timing. Needs daily opportunities to sprint in a safely enclosed area; a few short bursts of running satisfy their exercise needs more than long walks..
Whippet Male vs Female Size Differences
Male and female Whippets differ noticeably in size, a pattern common in medium breeds. Males typically weigh 25–40 lbs, while females weigh 21–35 lbs. Both sexes stand 18–22 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 Whippets 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 Whippet Overweight?
To determine if your Whippet is at a healthy weight (25–40 lbs target):
- Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
- Waist check: Viewed from above, there should be a visible waist behind the ribs
- Tuck-up: From the side, the abdomen should tuck up behind the rib cage
Their coat type allows for relatively easy visual assessment. If your Whippet is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Mitral Valve Disease and other conditions.
Whippet Weight Management Tips
Maintaining your Whippet at a healthy weight between 25 and 40 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 Whippet'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 Whippet 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 Whippet 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
Plan on 0.5–0.8 cups of premium dry food daily for your adult Whippet, divided into morning and evening meals. Given this hound breed's predisposition to Mitral Valve Disease, discuss dietary approaches that may help manage this risk with your vet.

Whippet Weight by Age Table
The following table shows expected weight ranges for male and female Whippets at key developmental milestones. Individual dogs may fall slightly outside these ranges depending on genetics, nutrition, and activity level. Consult your veterinarian if your Whippet's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 9.0–11.0 | 7.6–9.4 |
| 6 months | 19.8–24.2 | 16.8–20.6 |
| 9 months | 28.9–35.1 | 24.5–29.9 |
| 12 months | 36.1–43.9 | 30.6–37.4 |
Health Risks of Incorrect Weight in Whippets
Both underweight and overweight conditions pose serious health risks for the Whippet. Understanding these risks reinforces the importance of maintaining your dog within the 25–40 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Mitral Valve Disease. Overweight Whippets 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 Whippet consistently below 25 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 Whippet appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
