The Whippet is a medium-sized sighthound that looks like a small Greyhound and can reach speeds of around 35 mph. Despite that speed, Whippets are calm, gentle house dogs that are happy to sleep most of the day.

When does a Whippet stop growing?
As a medium breed, Whippets typically reach adult weight by around 12-14 months. Smaller breeds like the Whippet reach full height and fill out fairly close together, so growth tends to look "done" all at once.

A typical adult Whippet (35 lb, average activity) needs roughly 891 kcal/day — about 0.5 lb (2.1 cups) of dry kibble per day, which works out to around $31/month at typical kibble prices. Fresh or subscription-style food usually costs more, around $356/month for the same dog. These are population-level estimates — use the calculator below for a number based on your dog's actual weight and food type, or see the Whippet feeding chart for puppy amounts by month.

- Sighthounds have little body fat and can be sensitive to some anesthetics — make sure your vet knows the breed.
- Their thin skin tears easily, so cuts and lacerations are a common reason for vet visits.
- Heart murmurs (mitral valve disease) and some inherited eye conditions are documented in the breed.
This is general breed-level information, not a diagnosis or a prediction for any individual dog. Talk to your vet about health screening and preventive care specific to your dog.
