Are Brussels Griffons good in hot weather?

How Brussels Griffons handle the heat

The cooling problem

Brussels Griffons are brachycephalic, meaning their short muzzle leaves little internal surface for panting to cool the blood. In warm weather this is a serious limitation, not a quirk, and it is why flat-faced breeds are massively over-represented in vet heatstroke cases every summer.

Practical summer management

Shift walks to early morning and late evening, and skip them entirely on the hottest days. Carry water on every outing, provide deep shade in the garden, and give access to cool floors indoors. The pavement test is simple: press the back of your hand to the ground for seven seconds, and if it is too hot for your hand it is too hot for paws.

Never leave any dog in a parked car, conservatory, or caravan, even briefly and even with a window open. Interior temperatures climb to lethal levels within minutes.

Exercise in warm weather

Brussels Griffons have moderate exercise needs, which makes summer easier to manage. It is straightforward to shift their activity into the cooler hours without leaving them under-exercised.

Personality and summer walks

Alert dogs keep monitoring their surroundings even in high heat, and that ongoing vigilance can mean less genuine rest during the hottest part of the day. A loyal dog keeps pace with its owner on a hot walk rather than dropping back into the shade on its own, so the owner has to be the one who decides the outing is over. Curiosity keeps a dog moving and investigating even in warm conditions, since an interesting scent trail does not stop being interesting just because the day is hot.

Heat, training and behaviour

Teaching a dog to settle in the shade

Brussels Griffons respond reasonably well to basic settle training, which helps on hot days when the aim is simply to keep the dog calm and off its feet during the warmest hours.

Barking and restlessness in a heatwave

Brussels Griffons bark a moderate amount day to day, and that can increase during a heatwave if the dog is uncomfortable and unable to settle properly.

Family and other pets in a heatwave

Brussels Griffons need closer supervision around children at the best of times, and a hot day adds the extra risk of a dog overexerting itself during boisterous play rather than resting when it should. They typically share a house with a cat without issue, and both species tend to gravitate to the same cool spots during a heatwave.

Cost and ageing in hot weather

Brussels Griffons typically live 12 to 15 years, and older dogs of any breed regulate heat less efficiently than a fit adult, so senior brussels griffons need shorter, cooler outings and closer watching during a heatwave. Insurance for a Brussels Griffon in the UK typically costs about £18 to £42 a month, and heatstroke is exactly the kind of sudden, serious vet visit that cover exists for. A Brussels Griffon puppy, usually priced around £800 to £2000, overheats more easily than an adult dog as well, since puppies have less developed temperature regulation and tire without always showing it.
