Not every dog is made for sunny, sizzling afternoons. While many pups enjoy soaking up the sun, others struggle when temperatures rise. Thick coats, flat faces, or heavier builds can make certain breeds more likely to overheat and feel uncomfortable. As a dog mom, I’ve seen how quickly heat can take a toll on a fur baby not built for high temperatures. Knowing which breeds are more sensitive to heat helps us keep them safe, comfortable, and healthy when the sun shines a little too fiercely.

Bulldogs have short noses and compact airways, which make it harder for them to cool down efficiently. They can get overheated in just a short time when temperatures rise. Their stocky build also means they may tire faster in hot weather. Even a quick walk during a warm afternoon can leave them panting heavily. Bulldogs truly thrive best when kept cool and shaded.

Pugs are adorable with their squishy faces, but that flat snout can be a real disadvantage in hot weather. They often struggle to regulate their body temperature and can become overheated quickly. Their playful personalities can trick you into thinking they’re fine, but overexertion in heat is dangerous for them. Extra water and cool rest spots are must-haves for these little charmers.

With their thick, dense double coat, Chow Chows are practically wearing a fur blanket year-round. This heavy coat is perfect for winter but can be a challenge in hot months. They can overheat quickly, especially if paired with intense activity. Grooming and keeping them in cooler environments is essential for their comfort and health.

These small companions have long, flowing coats that can trap heat, especially when not trimmed in summer. Combined with their short muzzles, they’re not the best at cooling themselves down. They love snuggling, but too much heat can make them sluggish or uncomfortable. A cool indoor space is often their happy place during hot days.

Boxers are energetic and playful, but their short noses and muscular builds can make warm weather exhausting for them. They tend to overheat faster than you might expect during outdoor play. Their enthusiasm means they may keep going even when they’re too hot, so careful monitoring is important. Plenty of shade and water help keep them safe in the heat.

Known for their giant size and thick coats, Saint Bernards were bred for cold mountain climates. Heat can weigh heavily on them, leading to quick fatigue. Their massive bodies require extra effort to regulate temperature, making hot weather especially challenging. They’re happiest lounging in cool spaces rather than baking in the sun.

French Bulldogs share the same breathing challenges as other flat-faced breeds, making heat a real danger. Their small size doesn’t mean they handle the sun better; if anything, they’re just as sensitive. Quick bursts of activity in hot weather can leave them struggling to catch their breath. Indoor play is often safer for them during the summer months.

Akitas have thick double coats designed to keep them warm in icy conditions. That same fur can trap heat in warmer months, leading to discomfort. They may be stoic, but that doesn’t mean they’re immune to heat stress. Regular grooming and plenty of cool water are vital during hot days.

Cavalier King Charles Spaniel

These sweet-natured dogs have long, silky coats that can become stifling in high heat. While they love to play, they can quickly tire in warmer conditions. Their gentle nature often makes them quiet about discomfort, so it’s important to watch for subtle signs of overheating. A shaded rest spot is perfect for them on sunny days.

Great Danes may have short coats, but their large size makes them vulnerable to overheating. Their bodies generate and retain heat quickly, especially during physical activity. They can tire faster in warm conditions, and heavy panting is a sign they’re struggling. Gentle walks during cooler times of the day help keep them comfortable in hot weather.

Mastiff

Mastiffs are large and heavy-bodied, which means they can heat up more quickly than smaller breeds. Their short noses also reduce their ability to cool themselves effectively. Extended time in hot weather can be risky, especially with vigorous exercise. They benefit from early morning or evening walks when the temperatures drop.

Samoyed

Samoyeds have famously thick, fluffy coats meant for snow and cold. While they’re beautiful, this heavy insulation can make hot weather uncomfortable for them. Even with grooming, their fur retains a lot of warmth. They do best with plenty of shade, cool water, and limited midday activity.

Boston Terrier

Boston Terriers have short snouts and compact frames, which can lead to overheating during hot weather. They may love outdoor adventures, but their breathing can become strained in heat. Their playful, excitable nature means they don’t always slow down when they should. Keeping them indoors during peak sun hours helps keep them safe.

When temperatures climb, the fur babies on this list need a little extra care to stay safe. Heat sensitivity doesn’t mean they can’t enjoy time outside it just means we have to watch over them more closely when the sun is strong. Simple things like cooling mats, shady spots, and fresh water can make a huge difference. In the end, keeping them comfortable during hot days is one of the many ways we show our love and commitment to their happiness and well-being.
