Full-Grown Size

Whippets are a medium breed, reaching 25-40 lbs at full maturity. Medium breeds generally reach full size between 10-16 months.

With a typical weight of 25-40 lbs and lifespan of 12-15 yrs, the Whippet requires thoughtful care tailored to their specific breed characteristics. We've organized the most relevant information below.

Growth Timeline

Understanding breed tendencies equips you to anticipate needs, even as individual personalities vary. Whippets with moderate energy levels strike a good balance between activity and relaxation.

Weight Chart by Age

Care that accounts for breed predispositions leads to earlier detection and better prevention. Whippets have particular requirements based on their medium size, light shedding level, and genetic predispositions to heart disease and eye problems.

Preventive veterinary care, following AAHA guidelines of annual exams for adults and biannual exams for seniors, enables earlier detection of breed-related conditions. With 3 known predispositions, proactive screening is particularly important for Whippets.

Male vs Female Size

The key to a happy, healthy Whippet is matching your care approach to their breed characteristics. Activity needs are individual, not just breed-determined — age, health status, and temperament all modify the baseline.

Factors Affecting Size

Several breed-specific considerations deserve attention beyond routine care protocols. As a hound breed, the Whippet has instincts and behaviors shaped by centuries of selective breeding for specific tasks.

Many experienced Whippet owners recommend a balanced mix of physical activities and brain games.

Mental stimulation is as important as physical exercise for Whippet. Boredom is the root cause of most destructive behavior — not disobedience. Puzzle feeders, scent work, and novel experiences challenge your Whippet's mind in ways that a standard walk cannot. Change up the routine regularly: the same toys and the same routes lose their enrichment value quickly.

When They Stop Growing

Early intervention consistently produces better outcomes and lower costs than reactive treatment for breed-associated conditions. Watch for early signs of heart disease, maintain regular veterinary visits, and keep your dog at a healthy weight — obesity exacerbates nearly every health condition Whippets are prone to.

Strategic preventive care targeted to known breed risks represents the highest-return investment in your pet's long-term health.

Consistent daily structure — including predictable meal times, exercise, and rest periods — reduces anxiety and supports behavioral stability. Include scheduled feeding times, exercise sessions, grooming, and quiet rest periods. Even moderate-energy breeds thrive with predictable schedules.

Veterinary Care Schedule for Whippets

Keeping up with preventive veterinary care is one of the most important things you can do for your Whippet. Here is the recommended schedule:

Life StageVisit FrequencyKey Screenings
Puppy (0-1 year)Every 3-4 weeks until 16 weeks, then at 6 and 12 monthsVaccinations, deworming, spay/neuter (consult AVMA guidelines on optimal timing) consultation
Adult (1-7 years)AnnuallyPhysical exam, dental check, heartworm test, vaccination boosters
Senior (7+ years)Every 6 monthsBlood work, urinalysis, Heart Disease screening, Eye Problems screening, Anesthesia Sensitivity screening

Whippets should receive breed-specific screening for heart disease starting at 3-5 years of age or earlier if symptoms appear. Early detection significantly improves treatment outcomes and quality of life.
