Whippets are a generally healthy breed but can be genetically predisposed to deafness, worth screening for with regular veterinary checkups. Their thin coat and low body fat mean they get cold easily and have limited natural insulation — a coat or sweater in cold weather isn't just for looks.
A quality diet in measured portions matched to activity level; Whippets have a naturally lean build, so a visible waist and some rib definition is normal and healthy for the breed, not a sign of underfeeding.
The short, smooth coat needs minimal brushing — a low-maintenance breed coat-wise, though the breed's sensitivity to cold means outdoor time in winter should be limited or coat-supported.
Gentle and eager to please, Whippets train well with positive reinforcement. As a true sighthound, recall around fast-moving small animals can be unreliable, so secure fencing matters for off-leash time.
The Whippet was developed in 19th-century England by crossing small Greyhounds with terriers, originally bred by working-class fanciers for informal racing and small-game coursing — sometimes called the "poor man's racehorse." The result is a sighthound with genuine Greyhound-level speed in a smaller, more companionable package.
Despite their racing heritage, Whippets are famously calm, gentle housedogs — capable of short bursts of remarkable speed but content to spend most of the day relaxing, often described as couch potatoes between sprints.
