How do I keep a West Highland White Terrier comfortable and safe during a heatwave?

Published October 30, 2026

The short answer

Keep a West Highland White Terrier indoors through the heat of the day, walk her early and late on shaded routes, and keep her harsh white double coat hand-stripped or clipped to a practical length so air can circulate. Westies often have sensitive skin that flares in hot, humid weather, so rinse pollen and dust from her coat after evening walks and dry her thoroughly. Her terrier habit of digging for cool earth can wreck beds and test fences, so offer a shaded damp patch of her own. In KinsLe, Care Teams lets your household divide your Westie's walks, skin checks and water refreshes across the hot spell.

A small white terrier in very hot weather

A West Highland White Terrier handles a heatwave best with an indoor day, two walks in the cool margins, and extra attention to her skin. She is sturdier than she looks, but she is a small dog with a double coat, a low viewpoint close to heat radiating off pavements, and a breed tendency toward itchy, reactive skin that hot, humid, pollen-heavy weather aggravates. Her heatwave care is therefore as much dermatology as temperature control.

The Westie coat and summer skin

A Westie's harsh outer coat and soft undercoat should be kept groomed out during hot weather so air moves through it; a packed, dead coat over warm skin is where itch and soreness start. Whether she is hand-stripped or clipped, keep the length practical rather than skin-close, because that white coat covers pink skin that burns in strong sun, particularly on the ears and the bridge of the nose. Check the skin under her collar and in her armpits during the heatwave for redness, and keep her bedding washed and fully dry, since hot weeks plus sensitive skin punish any mustiness.

Terrier business: digging and patrolling in the heat

A Westie is an earth dog who digs to reach cool soil and who patrols her territory with conviction, and a heatwave does not switch either instinct off. Supervise her garden time, give her a shaded corner where digging is permitted and keep the soil there slightly damp, and watch the fence line after her sessions — a hole dug for cooling at noon can be a hole out by evening. Keep her occupied indoors with scent games and short training bursts, which tire a bright terrier without the heat cost of a midday walk.

Walks and water for a low-slung dog

Walk a Westie before the ground warms and again after sunset, choosing grass and shade because heat stored in pavement reaches a small, low dog from below as well as above. Test the surface with the back of your hand before setting out; if it is hot to hold, the walk waits. Carry water on even short outings in a heatwave — little dogs dehydrate proportionally fast — and offer it at every shady stop. At home, keep bowls in her main rooms and refresh them often. If she is a reluctant drinker, a few ice cubes to chase around a hard floor or some water offered after a game encourages her without forcing the issue.

Heat and skin warning signs in a Westie

A Westie panting fast and continuously indoors, drooling, or refusing to settle in the cool needs cooling and a call to the vet, and flat-out emergency signs are vomiting, wobbliness or collapse. Separately, in this breed, watch the skin through the hot spell: frantic scratching, chewing at the paws until they are stained and sore, or hot, red patches appearing under the coat deserve a vet conversation even if she seems cool enough, because heatwave skin flare-ups in Westies escalate quickly once the skin barrier breaks. Begin any heat cooling with tepid water on the belly and inner legs and moving air, and never delay the trip for a dog who has collapsed.

Keeping Westie care consistent across the family

A Westie's heatwave plan has fiddly parts — the post-walk rinse, the skin check, the supervised dig — that get skipped when everyone assumes someone else did them. KinsLe's Care Teams sets those jobs out as named, time-stamped duties on her profile, so whoever walks your Westie at dusk can see the morning skin check was done and the water was changed at noon.
