Heat in Dogs: Risks and Prevention

Heat in dogs is not just an inconvenience; it can quickly become a serious risk if measures are not taken. Unlike people, dogs regulate their temperature less efficiently and depend on their environment and your decisions to stay safe.

In this guide, you will find out why heat affects them so much, what habits reduce the risk on warm days, and what the most common mistakes are. The goal is for you to enjoy the summer with your dog with greater peace of mind, anticipating dangerous situations.

Why they suffer from heat

Dogs have a limited ability to dissipate heat. Their primary mechanism is panting and, to a lesser extent, sweating through their paw pads. When the ambient temperature rises, humidity is high, or the dog exerts itself, this "system" can fall short.

• Limited thermoregulation: Panting helps, but it is not always enough, especially in humid or unventilated environments.
• Coat and undercoat: Some breeds accumulate more heat; a dense undercoat can hinder dissipation if there is not good ventilation.
• Short snout (brachycephalic): Bulldogs, pugs, or boxers often have more difficulty cooling the air when breathing.
• Size and physical condition: Puppies, older dogs, overweight dogs, or those with little training can tire more quickly.
• Hot surfaces: Asphalt, sand, and dark floors accumulate heat and can cause discomfort or injuries to the paw pads.
• Stress and excitement: Intense games, travel, or new environments increase body temperature.

Furthermore, heat does not affect everyone equally. A dog accustomed to a temperate climate may feel it more during a heatwave, and a change in routine (more outings, more car rides, more activity) can increase the risk without you realizing it.

Protective measures

Prevention is based on reducing heat exposure, facilitating cooling, and planning activities during safe hours. Small changes at home and during walks make a big difference.

Hydration

Hydration is the first shield against heat in dogs. It's not just about "providing water," but about making it easy for them to drink regularly, even when they are distracted or away from home.

• Water always available: Place several bowls at home, especially near their resting area.
• Fresh, not ice-cold water: Refresh the bowl several times a day to keep it appealing.
• Outside: Carry a bottle and a portable water dispenser; offer small sips during shaded stops.
• Wet food or "toppings": Adding a little water to their food or using wet options can help increase fluid intake.
• Refreshing treats: A practical option is Functional Ice Creams, useful for encouraging water consumption and providing a moment of coolness without complications.

Avoid forcing large amounts of water all at once after intense exertion. It's better to offer small, frequent sips and allow them to recover in a well-ventilated place.

Safe walks

Timing and ground surface are key. In summer, a "normal" walk can become excessive exertion if done in the sun or on scorching surfaces.

• Choose cool hours: Early morning and late evening/night are usually the safest.
• Seek shade and green routes: Parks with trees, dirt paths, and grassy areas reduce the thermal load.
• Reduce intensity: Replace running and games with quiet walks, sniffing, and frequent stops.
• Ground test: Place the back of your hand on the asphalt for 5 seconds; if it's too hot for you, it can also harm their paws.
• Protect paw pads: Before going out, apply a specific product like Maikai Paw Pad Protector to help keep them well-maintained and more resistant to friction and the typical dryness of summer.

If your dog shows discomfort when walking, stops, lifts a paw, or constantly seeks shade, it's a sign to shorten the walk and return to a cool place.

Warning signs

Recognizing the signs associated with excessive heat in time can prevent the situation from worsening. Observe their behavior and don't just attribute it to "laziness" or "normal tiredness."

• Very intense or noisy panting that doesn't subside with rest.
• Very red tongue or darker gums than usual.
• Weakness, incoordination, or difficulty getting up.
• Excessive drooling or an anxious appearance.
• Vomiting or diarrhea after heat exposure.
• Refusal to walk or constant licking of the paws (possible discomfort in paw pads).

At the first sign of concern, stop the activity, seek shade, offer water in small amounts, and cool gradually (without sudden changes). If symptoms are intense or do not improve, consult a veterinary professional.

Common mistakes

Many problems related to heat in dogs occur due to routines that seem harmless. Correcting these mistakes immediately reduces the risk.

• Leaving the dog in the car: Even with windows partially open, the temperature can rise quickly. Always avoid this.
• Walking at midday: Direct sun and hot asphalt multiply the effort and the risk to paw pads.
• Intense exercise "because they love it": Some dogs don't self-regulate well; if they get excited, they continue even if they're struggling.
• Inadequate muzzle: Certain muzzles make panting difficult. If a muzzle is needed, prioritize one that allows panting and drinking.
• Extreme shaving without criteria: In some dogs, the coat protects from the sun and heat; consult how to do it correctly according to their coat type.
• Relying only on a fan: It helps, but it doesn't replace actual shade, water, and an adequate ambient temperature.
• Using ice abruptly: Sudden cooling can be counterproductive; fresh cloths, ventilation, and progressive cooling are better.

A practical approach is to plan the day: short walks during cool hours, indoor sniffing activities, rest in a ventilated area, and a hydration routine. This way, your dog maintains its well-being without sacrificing activity.

FAQ

Why is heat more dangerous for dogs than for people?

Because they regulate temperature less efficiently: they depend on panting and have less ability to sweat. In addition, their coat and certain conformations (such as a short snout) can hinder heat dissipation.

How do I know if the ground is too hot for their paws?

Do the 5-second test: place the back of your hand on the asphalt. If it's uncomfortable to keep it there, it's better to avoid that surface and look for shade, dirt, or grass.

What can I do to make them drink more water in summer?

Offer fresh water at several points, carry a portable water dispenser on walks, and try options that encourage intake, such as refreshing treats. Keep sips frequent and small when it's very hot.

Is it a good idea to wet them completely to cool them down?

It can help if done gradually and with cool (not ice-cold) water, especially in areas like paws, belly, and neck. Avoid abrupt changes and prioritize shade and ventilation.

What signs indicate that I should stop the walk and go home?

Very intense panting that doesn't subside, weakness, incoordination, refusal to walk, very red or dark gums, excessive drooling, or general discomfort. In these cases, find a cool place, hydrate slowly, and consult if it doesn't improve.
