Whippet Growth Stages

Understanding the typical growth stages helps you know what to expect as your Whippet puppy grows.

Neonatal

0–2 weeks

Puppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.

Socialization

3–12 weeks

Eyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.

Juvenile

3–6 months

Rapid growth continues. Puppies become more independent, start teething, and develop coordination.

Adolescent

6–12 months

Growth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.

Young Adult

12–15 months

Growth is nearly complete. Your puppy is filling out and approaching adult proportions.

Adult

15+ months

Your puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.

Whippet FAQ

How much will my Whippet puppy weigh as an adult?

Most adult Whippets typically weigh between 25 and 40 lb. Males often land in the 30–40 lb range, while females may finish lighter at 25–35 lb.

At what age is a Whippet fully grown?

Whippets usually reach adult weight between 12 and 14 months. Their lean build means they can look lanky well into adolescence.

How accurate is a Whippet puppy weight chart?

Charts show typical trends, not guarantees. Whippets are naturally lean — visible ribs on a fit Whippet are normal and not a sign of being underweight. Track the trend over weeks.

My Whippet looks skinny — is that normal?

Usually yes. Whippets carry almost no body fat by design; a slight waist tuck-up and faintly visible ribs are the breed's normal athletic shape. Only your vet can confirm whether an individual puppy is too thin.

How much should I feed my Whippet puppy?

Feed measured meals of a quality puppy food and adjust by body condition. Do not try to bulk up a lean Whippet with extra food — their slim frame is correct. Ask your vet about portions.
