Whippet Breed Profile and Growth Guide

Breed Overview

The Whippet is a graceful, medium-sized sighthound that originated in England during the 19th century. Bred by crossing Greyhounds with smaller terriers, Whippets were valued for their speed and agility, excelling in hunting rabbits and later in racing. Today, Whippets are beloved companions known for their elegance, affectionate nature, and surprising adaptability.

Whippets are gentle, intelligent, and affectionate with their families. Despite their athletic build, they are famously calm indoors and often called “couch potatoes” when not exercising. However, outdoors, they display their natural sprinting ability and prey drive, requiring secure areas for free running.

Size category: Medium
Whippets typically weigh 25–40 lbs as adults. Growth tracking is important for this breed to ensure lean muscle development without excess weight. As an athletic dog with a slim frame, keeping them within a healthy weight range helps prevent joint strain and supports long-term health.

How Much Bigger Will My Whippet Puppy Get?

Whippets experience fast growth in the first 6 months, with most reaching around 50% of their adult weight by 4 months. By 9–10 months, they are usually close to full adult height, but may continue filling out until 14–16 months.

• 50% of adult weight by ~4 months
• 75% of adult weight by ~7–8 months
• Near full size by 12 months

Rule of Thumb:
To estimate adult size, double your Whippet’s weight at 16 weeks for a fairly accurate prediction.

Exception:
Unlike giant breeds, Whippets complete growth relatively early and rarely continue beyond 16 months.

Whippet Growth Tips

Nutrition

• Feed a high-quality puppy formula suited for medium-sized breeds.
• Offer 3–4 meals daily until 6 months, then transition to 2 meals per day.
• Avoid overfeeding, as excess weight can put stress on their slender frame and joints.

Exercise

• Whippet puppies should enjoy gentle play and short walks, with plenty of free playtime in safe areas.
• Avoid forced running or long-distance jogging until growth plates close (around 12–14 months).
• Mental stimulation through training and interactive toys helps balance their calm indoor nature and bursts of energy.

Health Watch

• Whippets are generally healthy but may be prone to hip dysplasia and luxating patella if overexercised during growth.
• They have thin skin and low body fat, making them sensitive to cold. Puppies may need coats in chilly weather.
• Keep weight monitored closely, as even a small amount of excess fat is noticeable and unhealthy on their lean build.
