Yes, dogs can wear a raincoat during hot, humid weather—but only for short outings and with a highly breathable waterproof design. A raincoat should keep rain out without trapping heat inside.
One of the most common questions dog owners ask during summer is:
"Will my dog get too hot wearing a raincoat?"
Some people worry about their dog getting soaked, while others worry that a raincoat will trap too much heat.
The real question is not whether dogs can wear a raincoat.
It is whether they can continue to release body heat while wearing one.
A raincoat is designed to reduce prolonged exposure to rain, not to keep dogs outdoors longer.
Summer rain often comes with high temperatures and high humidity. If a raincoat lacks breathability, heat and moisture can quickly build up inside the coat, making your dog feel hot and uncomfortable even during a short walk.
Why Can Raincoats Cause Overheating in Summer?
Unlike humans, dogs cannot cool themselves by sweating over most of their bodies.
Instead, they primarily regulate body temperature through:
- Panting
- A small number of sweat glands in their paw pads
- Releasing heat through their ears and body surface
When high temperatures, high humidity, and poor airflow occur at the same time, their cooling system becomes much less efficient.
If a dog is also wearing a non-breathable raincoat, heat and moisture become trapped inside the coat, making it much easier for the dog to overheat.
Many people have experienced the same thing themselves. You put on a completely waterproof raincoat during a heavy downpour. The rain stays outside, but after just a short walk, the inside of the raincoat becomes hot, humid, and soaked with sweat.
People often joke:
"It's pouring outside, but it's raining inside my raincoat too."
The same thing can happen to dogs.
A raincoat that only blocks rain but cannot release body heat and moisture may leave your dog's coat damp from the inside, even without rain getting through.
That is why, in summer, breathability is just as important as waterproof protection.
🌧️📊 When Should Dogs Wear a Raincoat?
| 🌧️ Situation | Recommendation | Why |
|---|---|---|
| Light rain and a short walk | ✅ Recommended | Helps keep the coat dry and makes cleanup easier. |
| Steady rain during a bathroom break | ✅ Recommended | Reduces prolonged exposure to rain and keeps the coat from becoming soaked. |
| Heavy rain with a necessary outing | ✅ Recommended | Helps keep your dog dry, but the outing should remain brief. |
| Hot, humid weather without rain | ❌ Not Recommended | There is no reason to increase heat retention when rain protection is not needed. |
| Long outdoor activities | ⚠️ Depends on conditions | Take regular breaks and remove the raincoat when appropriate to help your dog cool down. |
Not Every Raincoat Is Suitable for Summer
Many raincoats focus on waterproof performance while overlooking something equally important: breathability.
If moisture cannot escape, your dog's body heat and humidity remain trapped inside the coat, even if rain never gets through.
This trapped heat is especially noticeable for:
- Long-haired dogs
- Double-coated breeds
- Highly active dogs
A summer raincoat should not just keep rain out.
It should also allow excess heat and moisture to escape, helping your dog stay comfortable throughout the walk.

📌 PETT2GO Expert Observation
Many people assume that if it is raining in summer, dogs should automatically wear a raincoat.
We look at it differently.
The more important question is:
Can this raincoat help your dog stay cool while staying dry?
A high-quality raincoat should not simply block rain. It should also allow the heat and moisture produced during movement to escape.
If a raincoat keeps rain out but traps all the heat inside, it may not be the most comfortable choice for summer adventures.
📝 Summer Raincoat Tips
① Before You Head Out
- Avoid walking during the hottest part of the day.
- Choose a raincoat that combines waterproof protection with excellent breathability.
- Make sure your dog is healthy and comfortable before heading outside.
📌 Quick Tip: During summer rain, keep walks focused on bathroom breaks or short outings rather than long exercise sessions.
② During the Walk
- Watch for heavier-than-normal panting.
- Take breaks whenever needed.
- If the rain stops and conditions allow, remove the raincoat to help your dog cool down.
📌 Quick Tip: The goal is not simply to stay dry. It is to keep your dog comfortable throughout the walk.
③ After Returning Home
- Dry your dog's paws and belly thoroughly.
- Remove the raincoat and allow the coat to air out.
- Check that the fur and skin are no longer damp before settling indoors.

Frequently Asked Questions FAQ
Q1: Should my dog wear a raincoat during summer rain?
Not always. For a brief walk in light rain, some dogs may not need one if they can be dried immediately afterward. However, during steady rain or necessary bathroom breaks, a breathable raincoat helps keep the coat dry while reducing cleanup afterward.
Q2: Can a raincoat make my dog overheat?
Yes. If the weather is hot and humid, the walk is too long, or the raincoat lacks breathability, heat and moisture can build up inside the coat. Choosing a waterproof yet breathable raincoat and keeping outings short helps reduce this risk.
Q3: Which dogs are more likely to overheat?
Extra care should be taken with brachycephalic breeds, senior dogs, overweight dogs, double-coated breeds, and highly active dogs.
Q4: How can I tell if my dog is getting too hot?
Watch for signs such as excessive panting, slowing down during the walk, frequently stopping to rest, reluctance to continue walking, lethargy, or unusual fatigue. If these signs appear, stop the walk, move to a shaded area, offer water, and allow your dog to cool down.
Summer rain is not just about getting wet.
It is also about managing heat.
A good raincoat should not simply keep rain out. It should also allow excess body heat and moisture to escape.
The most comfortable raincoat keeps your dog dry without trapping heat inside.
