With summer approaching, many dog owners begin to ask a crucial question: When is it too hot to walk your dog? While sunny days can be ideal for getting outdoors, high temperatures can turn a simple walk into a dangerous activity for your furry friend.

Dogs are far more vulnerable to heat than humans. Walking them in the wrong conditions could lead to burned paws, dehydration, or even life-threatening heatstroke. This comprehensive guide explains what temperatures are safe, which factors affect your dog’s tolerance to heat, and how to protect them when the sun is shining.

Why Hot Weather Is Risky for Dogs

Dogs don’t sweat like humans do. They regulate their body temperature through panting and small sweat glands in their paws. This method is far less effective in extreme heat, especially if humidity is also high.

Here are the main risks of walking dogs in hot weather:

  • Overheating and heatstroke: A serious condition where a dog’s body temperature rises above 40°C.
  • Burned paw pads: Pavements, tarmac, and sand can become dangerously hot and cause burns or blisters.
  • Dehydration: Dogs can lose a lot of moisture through panting and need regular access to water.
  • Increased heart rate and fatigue: Especially dangerous for older dogs or those with heart and respiratory issues.

Temperature Guide: How to Know When It Is Too Hot To Walk Your Dog?

Understanding the risks associated with different temperature ranges is vital. Use this guide to make safe decisions:

  • ✅ Below 20°C: Safe for Most Dogs

Most dogs can comfortably enjoy walks in these conditions. Make sure they stay hydrated and don’t overexert themselves.

  • ⚠️ 20–23°C: Caution Required

Still acceptable for many dogs, but you should shorten the walk and avoid midday heat. Brachycephalic breeds (like Bulldogs and Pugs), elderly dogs, or those with health issues may struggle in these conditions.

  • ❌ 24–26°C: Risk of Overheating

This is approaching the danger zone, particularly on sunny days when pavements can be much hotter than the air. Short walks only, preferably in the early morning or late evening.

  • 🚫 27°C and Above: Too Hot to Walk

This is considered too hot to walk your dog. Even short walks on hot surfaces can cause burns and severe overheating. Keep your dog indoors and find cooler, shaded areas for short toilet breaks only.

Dogs Most at Risk in the Heat

Some dogs are more sensitive to heat and may suffer more quickly, even in moderate temperatures:

  • Brachycephalic breeds (e.g. Pugs, French Bulldogs, Shih Tzus)
  • Elderly dogs
  • Puppies
  • Overweight dogs
  • Dogs with heart or respiratory issues
  • Dark-coated dogs (absorb more heat from the sun)

Always consider your dog’s individual needs before heading out in the heat.

Signs Your Dog Is Too Hot or Overheating

Recognising the early signs of overheating can save your dog’s life. Keep an eye out for the following symptoms:

  • Heavy or excessive panting
  • Bright red tongue or gums
  • Drooling
  • Vomiting or diarrhoea
  • Disorientation or confusion
  • Weakness or collapsing
  • Glazed eyes or lack of coordination

If your dog shows any of these signs, move them to a shaded or cool area immediately, offer water, and seek veterinary help.

How to Safely Walk Your Dog in Warm Weather

If temperatures are borderline and you decide to go out, follow these safety tips to protect your pet:

🕓 Choose the Right Time of Day

  • Walk early in the morning or after sunset when temperatures drop.
  • Avoid walks between 10am and 4pm, which is the hottest part of the day.

🌳 Pick Shaded Routes

  • Choose parks, wooded trails, or shaded neighbourhood paths to reduce sun exposure.

💧 Bring Water

  • Carry fresh, cool water and a collapsible bowl.
  • Offer water breaks frequently, even if your dog doesn’t appear thirsty.

👣 Protect Their Paws

  • Avoid hot pavements and tarmac.
  • Walk on grass where possible.
  • Consider dog booties for extra paw protection.

🐾 Keep It Short

  • Opt for shorter walks and watch for signs of fatigue.
  • Let your dog set the pace.

Alternatives to Walks on Hot Days

There will be days when walking your dog simply isn’t safe. Luckily, there are plenty of indoor activities to keep them mentally and physically stimulated:

  • Indoor fetch or tug-of-war
  • Puzzle feeders and treat-dispensing toys
  • Scent games (e.g. hiding treats around the house)
  • Short training sessions to reinforce commands or teach new tricks

These activities not only keep your dog engaged but also help burn off energy in a safe environment.

FAQs 

What’s the best time of day to walk a dog in hot weather?

Early morning (before 8am) or late evening (after 7pm) is best to avoid intense heat and hot pavements.

How can I cool down my dog after a warm walk?

Offer water, move them into the shade or indoors, and use a damp towel or cooling mat to help lower their body temperature.

Is it safe to walk my dog in 25°C?

For many dogs, especially flat-faced breeds, this is already borderline dangerous. Stick to short walks in shaded areas during cooler parts of the day.
