Essential hot weather safety information for West Highland White Terrier owners in the UK. Westies are hardy Scottish dogs, but their white coat, short legs, and terrier nature create unique summer risks.
West Highland White Terriers are hardy dogs originally bred in Scotland for hunting vermin in rugged terrain. Their double coat provides excellent protection against UK weather, but their short legs bring them close to the ground where radiant heat is strongest. Their white coat also requires special sun protection.
Ideal conditions, full exercise fine
Normal exercise with water breaks and shade stops

☀️Westies & Sun Exposure: A Hidden Danger
West Highland White Terriers have white coats and often pink skin underneath, making them highly susceptible to sunburn and skin cancer (squamous cell carcinoma and malignant melanoma). Their white coat reflects less UV than it appears — UV rays can penetrate to the skin, especially on the belly, inside of the ears, nose, and areas with thinner fur. Westies are over-represented in veterinary skin cancer cases. Always use pet-safe sunscreen on exposed areas during prolonged sun exposure.
Get your Westie to the coolest available area with air movement.
A Westie's double coat holds water well. Apply cool (not icy) water all over, focusing on belly, groin, and paw pads. The dense undercoat will hold moisture for prolonged cooling.
Position a fan to blow across their wet coat. The moisture held in their double coat will keep cooling for longer.
Let them drink small sips slowly. Do not force water into the mouth of an unconscious dog.
Even if your Westie appears to recover, heatstroke can cause delayed internal damage. Always seek veterinary advice after a suspected overheating episode.
Before walking your Westie in warm weather, always test the ground temperature:
Westies have short legs (only 25-28cm at the shoulder), putting their body very close to hot pavement. Radiant heat from the ground can raise their core temperature significantly even on walks that feel fine to you. Walk on grass whenever possible.
West Highland White Terriers have one of the highest rates of skin cancer among all dog breeds. Their white coat and often pink skin offer limited UV protection. Squamous cell carcinoma and malignant melanoma are particular concerns. Check your Westie regularly for new lumps, sores that don't heal, or changes in existing skin spots — especially on the belly, inside the ears, nose, and around the groin. Apply pet-safe SPF sunscreen to exposed pink skin before prolonged sun exposure, and limit sunbathing in the garden, even on mild days.
Westies stand only 25-28cm tall, meaning their body is just centimetres above the ground. On a sunny day, the air temperature at ground level can be 10-15°C hotter than at human waist height. Pavement can reach 50°C+ when the air is only 25°C. This means a Westie walking on pavement in supposedly "safe" conditions may already be experiencing significant heat stress from below. Always choose grass or earth paths, and carry your Westie over hot surfaces when necessary.
Westies have a double coat: a soft, dense undercoat for insulation and a harsh, white outer coat for protection. Do not shave a Westie's double coat — it can permanently damage the coat texture and eliminate the natural insulating properties that help regulate temperature. Traditional Westie grooming uses hand stripping rather than clipping. If clipping is preferred, use a longer blade (at least 1cm) and never shave to the skin. Regular brushing removes the dead undercoat, improving air circulation and natural cooling.
Like many terriers, Westies have a "never give up" attitude. Bred to pursue vermin into dens, they will keep digging, chasing, and exploring long after they should stop. In hot weather, this determination can be dangerous — a Westie having fun won't recognise the signs of overheating. You must enforce rest breaks every 10-15 minutes during active play, even if your Westie seems eager to continue. Their determination is a wonderful trait, but in summer it needs careful management.
