Which defining size difference separates the finished Whippet from its Greyhound parent?

Answer

Whippets typically weigh 25 to 40 pounds, significantly less than the Greyhound's 60 to 70 pounds

The most crucial evolutionary difference between the modern Whippet and its larger Greyhound ancestor is size, which was a key factor in the breed's adaptability to modern living. Greyhounds are substantially larger, commonly weighing between 60 and 70 pounds. The Whippet, however, was intentionally bred down to a much more manageable weight, generally falling between 25 and 40 pounds. This reduction in bulk is what allowed the sighthound profile to transition successfully from requiring extensive space to thriving in smaller dwellings or apartments.
