Whippet Dog Size: Full Growth Chart, Weight Ranges & Breed Profile

Whippet Breed Overview: The Medium-Sized Sighthound That Punches Above Its Weight

If you've been researching the Whippet dog size before bringing one home, you're asking the right question. These sleek sighthounds occupy a unique niche — they're medium-sized dogs that carry themselves with the grace of a large breed while fitting comfortably into apartments and smaller homes. Originating in Victorian-era Northern England (roughly the 18th–19th century), Whippets were bred by coal miners and working-class families who crossed small Greyhounds with terriers to create an affordable racing and rabbit-coursing dog. The breed earned the nickname "the poor man's racehorse" and received official AKC recognition in 1888.

Today's Whippet retains the athletic build and prey drive of its ancestors while serving primarily as a companion animal. They belong to the Hound Group and fall squarely in the medium size class, though their lean frame can make them appear smaller than their actual measurements suggest.

How Big Does a Whippet Get? Adult Weight and Height Breakdown

Understanding the Whippet dog size requires looking at both sex-specific standards and the natural variation within the breed. The AKC breed standard specifies ideal heights but allows weight to vary proportionally, which means two perfectly conforming Whippets can differ by 10–15 pounds.

Males typically stand 19–22 inches (48–56 cm) at the withers and weigh 30–40 lb (14–18 kg). Females are slightly smaller at 18–21 inches (46–53 cm) and 25–35 lb (11–16 kg). These are averages — some Whippets from show lines run stockier, while those from racing or coursing lines tend toward the leaner end of the spectrum.

Whippet Growth Milestones by Age

Most Whippets reach their full height by 12 months but continue filling out in chest depth and muscle mass until 18–24 months. Because they're deep-chested and narrow-waisted, a healthy Whippet should show a pronounced abdominal tuck when viewed from the side — don't mistake this natural sighthound conformation for being underweight.

Temperament & Personality: Five Core Whippet Traits

Whippets have a distinctive dual-mode personality that surprises many first-time owners. Here's what living with one actually looks like:

1. Calm Indoor Companions (The "Couch Potato" Mode)
Inside the home, Whippets are remarkably low-key. They gravitate toward soft surfaces and will claim couches, dog beds, and piles of laundry as their own. Expect your Whippet to spend 16–18 hours per day sleeping or lounging — this is normal, not a sign of lethargy. They curl up tightly and often burrow under blankets because their low body fat makes them feel cold easily.

2. Explosive Outdoor Athletes (The "Sprint" Mode)
Take that same Whippet outside, and the switch flips. They can accelerate to 35 mph in seconds and will chase anything that moves quickly — squirrels, leaves, plastic bags, other dogs. This prey drive is hardwired and will not be trained away. It's managed through secure fencing and leash discipline.

3. Sensitive and Emotionally Attuned
Whippets are acutely sensitive to tone of voice and household tension. Harsh corrections shut them down entirely — they'll freeze, tremble, or avoid you. They thrive in calm, predictable environments and bond intensely with their primary person. Many Whippet owners describe their dogs as "velcro" companions who follow them room to room.

4. Quiet and Low-Bark
Whippets rarely bark without reason. They might alert you to a stranger at the door or vocalize when playing, but they are not nuisance barkers. This trait makes them well-suited to apartment living and shared-wall housing.

5. Gentle with Familiar People, Reserved with Strangers
Unlike a Labrador who greets everyone as a long-lost friend, Whippets tend to observe newcomers from a distance before deciding to approach. They're not aggressive — just cautious. Early socialization (exposure to varied people, environments, and handling between 8–16 weeks) builds confidence and prevents timidity.

Exercise & Activity Requirements: Minutes, Types, and Safety Rules

Whippets need 40–60 minutes of structured exercise daily, but the type of activity matters far more than the duration. Here's how to break it down:

Critical safety note: Whippets should never be trusted off-leash in unfenced areas, regardless of recall training. Their chase instinct overrides obedience commands when prey is spotted. A Whippet in pursuit can cover 200+ yards in seconds and will not respond to calls. Always use a secure martingale collar or harness on walks — standard buckle collars can slip off a Whippet's narrow head.

During extreme temperatures (below 40°F / 4°C or above 85°F / 29°C), shorten outdoor sessions. Whippets lack insulating body fat and overheat or chill rapidly. A fitted dog coat is not optional in cold climates — it's a health necessity.

Health Issues Whippets Are Prone To

Whippets are generally one of the healthier purebred dogs, benefiting from a relatively large gene pool and functional breeding history that prioritized performance over extreme conformation. However, several breed-specific conditions deserve attention. Always consult your veterinarian for diagnosis and treatment of any health concern.

Whippets also have unique baseline bloodwork values that differ from other breeds. Their red blood cell count, hemoglobin, and packed cell volume (PCV) run naturally higher, while their white blood cell counts may run lower. Make sure your veterinarian is familiar with sighthound blood parameters to avoid misdiagnosing normal Whippet values as abnormal.

Grooming a Whippet: What You Actually Need

The Whippet's coat is one of the lowest-maintenance in the dog world, but "low maintenance" doesn't mean "no maintenance." Here's a realistic grooming schedule:

Weekly (5–10 minutes): Brush with a rubber curry brush or soft-bristle brush to remove loose hair and distribute skin oils. Whippets shed moderately year-round but lack an undercoat, so seasonal blowouts are minimal. A Kong ZoomGroom or Hertzko Soft Bristle Brush works well.

Monthly: Trim nails to just above the quick — Whippet nails grow quickly and long nails alter their foot mechanics, which matters for a breed built for speed. Use a guillotine-style clipper or a Dremel grinder if your dog tolerates vibration. Check ears for debris or odor and wipe with a vet-approved ear cleaner if needed.

As Needed: Bathe every 6–8 weeks or when visibly dirty. Use a gentle, dog-specific shampoo — Whippet skin is thin and prone to dryness and irritation from harsh products. Skin scrapes and abrasions are common (they have very little protective fat or fur), so inspect the body for cuts after outdoor play.

Dental Care (Daily Ideal, 3x/Week Minimum): Brush with enzymatic dog toothpaste. Small-to-medium breeds are predisposed to periodontal disease, and Whippets are no exception. Dental chews supplement but don't replace brushing.

Training & Intelligence: What Works (and What Doesn't)

Whippets are intelligent but independently motivated — they learn quickly when training is relevant to them and disengage when it isn't. They score moderately on working/obedience intelligence rankings but excel in activities that channel their natural athleticism.

Trainability Rating: Moderate (3/5). They're not a Border Collie that lives to work, nor are they a stubborn bulldog. They fall in the middle — cooperative but not obsessive about pleasing you.

Methods That Work:

• Positive reinforcement only. High-value food rewards (freeze-dried liver, chicken bits) and toy rewards for chase-motivated individuals. Clicker training is highly effective for Whippets.
• Short sessions (5–10 minutes). Whippets lose focus in repetitive drills. Train in brief bursts with clear criteria.
• Recall training with a long line. Start in low-distraction environments with a 15–30 foot training lead. Build reliability over months, not weeks. Never fully trust recall in open areas.
• Crate training from day one. Whippets appreciate den-like spaces and crate-train easily when introduced positively with meals and soft bedding.

Methods to Avoid: Shock collars, prong collars, alpha rolls, and any force-based correction. Whippets' emotional sensitivity means aversive methods create fear, shutdown, and avoidance behaviors — not compliance. If you're struggling with training, work with a certified force-free trainer (look for CCPDT or IAABC credentials).

Sports That Suit Whippets: Lure coursing, straight racing, agility (with appropriate jump heights), rally obedience, and nose work. Many Whippets also earn therapy dog certifications due to their calm, gentle demeanor in clinical settings.

Family Suitability: Kids, Other Pets, and Living Spaces

With Children: Whippets do well with gentle, dog-savvy children ages 8 and up. They are not robust enough for rough play — a toddler falling on a Whippet can cause real injury to the dog. Teach children to respect the dog's resting space (Whippets startle easily when sleeping) and never to chase or grab the dog. With proper supervision and child education, Whippets become devoted family companions.

With Other Dogs: Whippets generally enjoy the company of other dogs, especially sighthounds or similarly-built breeds. They play with a distinctive "run and chase" style that can overwhelm more sedate breeds. Multi-Whippet households are common because the dogs match each other's energy and play style.

With Cats and Small Pets: This is the challenging area. Whippets have a strong prey drive, and cats, rabbits, or small dogs that run may trigger a chase response. Some Whippets coexist peacefully with household cats (especially when raised together from puppyhood), but this is dog-dependent and should never be assumed. Always supervise interactions and provide the cat with elevated escape routes.

Apartment Living: Whippets are among the best breeds for apartments. They're quiet, medium-sized, and spend most of their time indoors sleeping. The key requirement is access to a secure outdoor space for daily sprinting. A nearby fenced dog park or a private yard (even borrowed from a neighbor via apps like Sniffspot) satisfies their exercise needs without requiring a large property.

Cost of Owning a Whippet: Purchase Price and Annual Expenses

Budgeting realistically for a Whippet prevents unpleasant surprises. Here's what to expect in the current market:

Purchase or Adoption Costs

When evaluating breeders, look for OFA (Orthopedic Foundation for Animals) health clearances on both parents, including cardiac evaluation and eye certification. Responsible breeders will happily share these results and ask you questions about your home and lifestyle.

Estimated Annual Care Costs

Emergency veterinary care is the wildcard. A single episode of a torn muscle or a swallowed foreign body can cost $2,000–$5,000. An emergency fund of $1,000–$2,000 or active pet insurance is strongly recommended.

Frequently Asked Questions About Whippet Size and Care

Is a Whippet a good first dog for a new owner?

Yes, with caveats. Whippets are forgiving of beginner mistakes in terms of grooming and exercise (they don't need hours of activity), but their sensitivity requires a calm household and their prey drive demands management. First-time owners who research the breed, invest in positive-reinforcement training, and commit to secure fencing tend to do very well. If you want a dog that can be off-leash at parks with zero risk, a Whippet is not the right first dog.

How much exercise does a Whippet need daily?

Plan for 40–60 minutes of total daily activity, split between two leash walks (20–30 minutes each) and at least one opportunity for high-speed running in a secure area (15–20 minutes, 3–5 days per week). Whippets are not endurance athletes — they're sprinters who need short bursts of intense exercise followed by long rest periods. A Whippet that gets adequate sprinting time is typically calm and settled indoors.

Are Whippets good with children?

Whippets are good with respectful, older children (8+) who understand how to interact gently with dogs. They are not suitable for toddlers who may grab, fall on, or startle the dog. Whippets have thin skin and lightweight frames — a 30-pound dog can be injured by a child who doesn't know boundaries. Supervision and child education are non-negotiable.

Can Whippets live with cats?

Some can, but it's never guaranteed. Whippets raised with cats from puppyhood have the best chance of coexistence, but the prey drive can emerge unpredictably. Never leave a Whippet unsupervised with a cat, even if they've coexisted peacefully for years. Provide cats with high perches and escape routes that the dog cannot access.

Do Whippets shed a lot?

No. Whippets have a short, fine single coat that sheds minimally. You'll find occasional short hairs on dark clothing or furniture, but they don't "blow coat" like double-coated breeds. Weekly brushing with a rubber curry brush keeps shedding nearly invisible.

What's the difference between a Whippet and an Italian Greyhound?

The primary difference is size. Italian Greyhounds are toy breeds standing 13–15 inches and weighing 7–14 lb, while Whippets are medium breeds at 18–22 inches and 25–40 lb. Italian Greyhounds tend to be more fragile and high-strung, while Whippets are sturdier and calmer. Both are sighthounds with similar temperaments and care needs, scaled to their size.

How cold is too cold for a Whippet?

Most Whippets become uncomfortable below 50°F (10°C) and should wear a fitted coat below 40°F (4°C). Limit outdoor time to bathroom breaks when temperatures drop below 20°F (-7°C). Their lack of body fat and thin coat provides virtually no insulation. Indoors, provide warm bedding and consider a sweater for resting, especially for senior Whippets.
