Whippet Weight Chart & Growth Guide

Q: What is a healthy adult weight range for a Whippet?

AKC lists adult Whippets at 25-40 lb, or about 11-18 kg. Height, frame, ribs, tuck-up, muscle, gait, and your veterinarian's body-condition score decide where an individual Whippet should sit.

Q: How much should a 6 month old Whippet weigh?

At around 6 months, many Whippets are roughly 17-31 lb depending on frame. Compare the number with ribs, waist, tuck-up, muscle, appetite, stool, gait, sprint recovery, and your veterinarian's advice.

Q: When do Whippets stop growing?

Many Whippets are close to adult height and weight by about 12 months, but muscle, chest, stamina, and mature condition can keep settling through 12-18 months.

Q: Are visible ribs normal on a Whippet?

Some outline can be normal because Whippets are lean sighthounds. Ribs should be easy to feel, but sharply protruding ribs, lost muscle, weakness, weight loss, or poor appetite should be checked.

Q: Is a 40 lb Whippet overweight?

Not automatically. Forty pounds can fit a tall, muscular Whippet, but it can be too much for a smaller frame. Use rib feel, tuck-up, hip padding, gait, recovery, and vet body-condition scoring.

Q: Why does my Whippet puppy look skinny after a growth spurt?

Whippet puppies often grow upward and lengthwise before muscle and chest finish. If appetite, stool, energy, muscle, and recovery are good, a leggy phase can be normal.

Q: How much do treats matter for a Whippet?

Treats matter because they can quickly soften a lean waist. Use small rewards and count training food as part of the daily intake.

Q: Do Whippets need more food in cold weather?

Some Whippets may need adjustment when activity, temperature, and indoor comfort change. Use body condition, weight trend, appetite, and recovery instead of automatically increasing food.

Q: When should I call the vet about Whippet weight or feeding?

Call your vet if weight drops quickly, appetite falls, vomiting or diarrhea continues, limping appears, a toe is swollen, skin tears occur, coughing or breathing changes appear, the dog collapses, or sprint recovery changes suddenly.

Updated weekly

Whippets are built to look lean, with a tucked waist and athletic muscle that can worry owners who expect a rounder dog. This guide reads the chart through sighthound shape, ribs, muscle, sprint-and-rest activity, food portions, and the difference between normal leanness and weight loss.

A Whippet should look athletic and tucked, but not sharp, weak, or losing muscle.

Quick answers

Whippet weight quick answers

Start here if you only need the practical answer. Whippets are supposed to look lean, but healthy leanness still includes muscle, easy recovery, and steady appetite.

Adult range

Most adult Whippets are about 25-40 lb

AKC lists adult Whippet weight at 25-40 lb, with males usually 19-22 inches and females 18-21 inches. Height and frame explain a lot of the range.

Growth timing

Many Whippets are close to adult size by 12-15 months

Height often slows before mature muscle and condition. Some Whippets look tall and thin during adolescence before filling into athletic adult shape.

Best check

Lean is normal; sharp is not

A healthy Whippet may look skinny to people used to stockier breeds. Ribs should be easy to feel, but protruding ribs, lost muscle, weakness, or poor appetite needs attention.

AWC guidance

Muscle tone matters as much as pounds

The American Whippet Club emphasizes proper weight and muscle tone for an active healthy life. Use sprint recovery, gait, rib feel, and hip padding with the scale.

Weight by age

Whippet Weight Chart by Age

Whippet puppies grow into lean, muscular medium sighthounds with a deep brisket, definite tuck-up, moderate bone, and a sprint-and-rest rhythm. The healthiest trend is steady gain with ribs that are easy to check, clear waist shape, smooth muscle, and comfortable movement.

Use this chart as planning context, not a diagnosis. The official adult range is 25-40 lb, but height, sex, family line, muscle, activity, appetite, cold comfort, injuries, and veterinary body-condition scoring decide the healthy target for an individual Whippet.

Age	Larger Frame	Smaller Frame
8 weeks	6-10 lb (2.7-4.5 kg)	5-8 lb (2.3-3.6 kg)
3 months	10-16 lb (4.5-7.3 kg)	8-13 lb (3.6-5.9 kg)
4 months	14-22 lb (6.4-10 kg)	11-18 lb (5-8.2 kg)
5 months	18-27 lb (8.2-12.2 kg)	14-22 lb (6.4-10 kg)
6 months	20-31 lb (9.1-14.1 kg)	17-26 lb (7.7-11.8 kg)
8 months	23-36 lb (10.4-16.3 kg)	20-30 lb (9.1-13.6 kg)
10 months	25-39 lb (11.3-17.7 kg)	22-33 lb (10-15 kg)
12 months	25-40 lb (11.3-18.1 kg)	23-35 lb (10.4-15.9 kg)
15 months	25-40 lb (11.3-18.1 kg)	24-36 lb (10.9-16.3 kg)
18 months	25-40 lb (11.3-18.1 kg)	24-36 lb (10.9-16.3 kg)

Maturity

When Does a Whippet Stop Growing?

Whippets are medium dogs, but their adolescent shape can look dramatic because height, chest, loin, and muscle do not mature at exactly the same time.

3-5 months

Fast puppy growth

This is a high-change stage. Weigh regularly, use measured meals, and keep play safe while coordination and legs change quickly.

5-8 months

Leggy sighthound phase

Many Whippets look tall, narrow, and tucked. That can be normal, but sharp bones, poor appetite, limping, or weakness should not be ignored.

8-12 months

Adult outline appears

Height and weight often slow, but the dog may still need time to add muscle, chest, stamina, and adult recovery.

12-18 months

Muscle and condition settle

For many Whippets, this stage is more about mature athletic condition than new height. Keep food matched to exercise, temperature, and body condition.

Key takeaway

Do not compare a Whippet to a stockier dog

A healthy Whippet should be lean and tucked, but not weak, sharp, or losing muscle. Judge trend, muscle, recovery, and vet body-condition score together.

Growth check

Signs Your Whippet Is Growing Well

A good Whippet growth trend is steady, athletic, and comfortable. Use these checks with the chart, calculator, and your veterinarian's advice.

Good signs

Weight rises gradually without sudden drops after appetite, food, stress, or activity changes.
Ribs are easy to feel under a thin layer of cover without looking sharply protruding.
A tucked waist and slight spine outline can be present while shoulders, loin, and thighs still feel muscled.
The puppy walks, turns, runs, and recovers without limping, toe swelling, stiffness, or reluctance.
Appetite, stool, dental comfort, cold comfort, energy, gait, and recovery stay consistent across check-ins.

Needs monitoring

Ribs, spine, hips, or shoulder points look sharp and muscle coverage is fading.
The waist and tuck-up soften after lower activity, cold-weather rest, or treat-heavy routines.
Sprint recovery worsens, the dog becomes unusually tired, or breathing seems different.
There is limping, toe swelling, skin tearing, yelping, or reluctance to bear weight.
Weight changes appear with vomiting, diarrhea, appetite loss, coughing, collapse, or sudden exercise intolerance.

Owner check

Feel the athlete, not just the ribs

A Whippet should feel lean and springy, with muscle over shoulders, back, loin, and thighs. The goal is athletic condition, not padding.

Weight factors

What Changes a Whippet's Weight?

Whippet weight is shaped by height, frame, muscle, sprint/rest activity, food, treats, temperature, age, dental comfort, and health. The number needs sighthound context.

Range

The official adult range is 25-40 lb

AKC lists 25-40 lb for adult Whippets. A 40 lb Whippet may be normal for a tall frame, while the same number could be too much for a smaller dog.

Shape

Sighthound leanness is expected

The standard describes deep brisket, definite tuck-up, moderate bone, and muscular power. A Whippet should not look like a rounder, heavier-bodied breed.

Muscle

Condition is more than low weight

AWC emphasizes correct weight and muscle tone. A light Whippet with poor muscle is not the same as a fit Whippet with a lean outline.

Activity

Sprint-and-rest routines shift calories

A Whippet that walks, plays, and runs safely may need different food than one resting through injury, bad weather, or lower winter activity.

Cold

Warm dry rest matters

AWC recommends warm, dry sleeping space. Cold discomfort can reduce activity, change appetite, and make a lean dog burn energy differently.

Health

Sudden changes deserve review

Weight loss, poor recovery, limping, toe swelling, skin tears, coughing, collapse, vomiting, diarrhea, or appetite loss should not be treated as a chart issue.

What this means

How to read this graph for Whippet

Use the male line for male puppies and the female line for female puppies, because Whippet dogs often grow at different rates through the first year.
Month-to-month progress matters more than one high or low weigh-in, especially during the faster early-growth months.
Use the live calculator after repeat weigh-ins, then compare the result back to this breed-specific chart to confirm the trend is still moving steadily.

When to re-check

<16 w weekly | 16-32 w biweekly | 32 w+ monthly

Re-check a Whippet every 2 to 4 weeks during growth, and sooner after appetite, activity, stress, or temperature-related changes.

Stages

Whippet Growth Stages

These stages help owners understand why a Whippet can look skinny, leggy, or suddenly more muscular during normal development.

8-12 weeks

New puppy baseline

Record starting weight, food brand, meal amount, stool quality, appetite, breeder notes, warmth, activity, and early vet findings.

3-5 months

Fast growth and coordination

Weigh often, measure meals, and keep play safe while legs, chest, and coordination change quickly.

5-8 months

Leggy adolescent outline

The puppy may look tall and narrow. Check ribs, tuck-up, muscle, gait, appetite, stool, and recovery before assuming underweight.

8-12 months

Adult range approaches

Many Whippets are close to adult height and weight. Portions and treats now affect the athletic waist quickly.

12-18 months

Mature athletic condition

Muscle tone, sprint recovery, safe off-lead outlets, dental care, and injury prevention become the main story.

Feeding rules

Whippet Feeding Rules for Healthy Growth

Rule 1

Use a balanced growth diet

Feed a complete and balanced puppy food until skeletal maturity unless your veterinarian gives different instructions.

Rule 2

Measure meals instead of guessing

Measured portions make the chart useful. Adjust from trend, body condition, activity, and recovery rather than from outline alone.

Rule 3

Track muscle and weight together

A Whippet can be light and still under-muscled, or heavier and still fit. Check shoulders, loin, thighs, ribs, and waist.

Rule 4

Count training rewards

Treats should stay a small part of daily calories. Use small rewards and subtract frequent training food from meals when needed.

Rule 5

Match food to activity and weather

Safe sprinting, long walks, cold weather, injury rest, and lower-activity weeks can all change calorie needs.

Rule 6

Change food gradually

A slow transition makes appetite, stool, skin, coat, and weight easier to interpret.

Feeding

How to Feed a Whippet at Different Ages

The exact amount depends on calories per cup, age, expected adult size, activity, temperature, body condition, muscle, health, and your veterinarian's plan. The routine matters as much as the number.

Feed the athlete, not the fear

Puppy

Growth should be steady

Use measured meals and a balanced puppy food. Track weight, stool, appetite, ribs, muscle, and recovery because Whippet puppies can look leggy before they fill out.

Adolescent

Activity can swing intake

A young Whippet that runs safely may need more than one resting through weather or injury. Adjust gradually from body condition.

Adult

Maintenance protects speed and comfort

Once adult weight settles, adjust portions around activity, treats, neuter or spay changes, cold weather, and body condition.

Senior

Watch muscle, teeth, and warmth

Older Whippets may need extra warmth and closer muscle checks. Ask your veterinarian before starting a major weight-loss plan or food change.

Treats

Rewards should not blur the waist

Training food counts. Use small pieces and keep treats below a small share of daily calories.

Vet review

Bring the full record

For a better target, bring weight history, food amount, calorie information, treat count, activity notes, body photos, recovery notes, and any limping, toe, skin, or cough concerns.

Warning signs

Whippet Weight Warning Signs

Use this page for tracking, not diagnosis. Call your veterinarian when weight changes appear with appetite, stool, mobility, skin, toes, breathing, warmth, or recovery problems.

Possible overweight signs

Ribs become hard to feel or the natural tuck-up starts to disappear.
Padding appears over the waist, loin, tail base, hips, shoulders, or thighs.
Sprint recovery slows, endurance drops, or the dog seems heavier on the move.
Treats, chews, leftovers, injury rest, or lower activity increased before weight rose.
Your veterinarian scores body condition above ideal or recommends a weight-control plan.

Possible underweight or urgent signs

Ribs protrude sharply or spine, hips, or shoulder points look harsh with poor muscle coverage.
Weight drops quickly or growth stalls while appetite, stool, energy, or hydration changes.
There is limping, toe swelling, yelping, skin tears, reluctance to run, or obvious pain.
There is coughing, breathing change, collapse, sudden exercise intolerance, or poor recovery after ordinary activity.
There is dental pain, bad breath with appetite change, vomiting, persistent diarrhea, or refusal to eat.
