When Does a Whippet Stop Growing?

The Whippet stops growing in height (target: 18–22 inches) around 12–15 months of age, but may continue adding weight toward 40 lbs for a few more months. Weighs 25 to 40 pounds with a lean, muscular build; any visible ribs are normal and not a sign of being underweight..

Early spay/neuter can affect growth plate closure, potentially resulting in a slightly taller but leaner adult.

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?

Is your Whippet at a healthy weight? The ideal range is 25–40 lbs (males 25–40, females 21–35). Check these three signs:

  • Ribs: Easily felt with light pressure; not visible but not buried under fat
  • Waistline: A clear narrowing behind the ribs when viewed from above
  • Abdominal tuck: The belly slopes upward from the ribcage to the hind legs when viewed from the side

If your dog fails any of these checks, consult your vet. One of the healthiest purebred dogs with few genetic issues, though veterinarians must be aware of their anesthesia sensitivity..

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

Adult Whippets (25–40 lbs) typically need 0.5 to 0.8 cups of high-quality dry food per day, divided into two meals. A formula suited to medium breeds provides appropriate nutrient density. Needs daily opportunities to sprint in a safely enclosed area; a few short bursts of running satisfy their exercise needs more than long walks.—adjust portions based on activity level. Budget $50–78/month for food costs.

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.

AgeMale (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.
