Perhaps you believe that rain is a major disruption in your daily life at times, but it appears that our dogs do not. They sometimes seem to enjoy and be excited about getting out while it's raining.

If this is the case for your dog you may be wondering: why is this happening? Is it dangerous for my dog to stay out in the rain? Well, there are multiple reasons for this, some of which are not caused for concern, while others may be. 

The "good" reasons include your dog enjoying the feeling of rain, wanting to mate in the rain, or simply enjoying the outdoors. It's also possible that he's spotted another animal outside, or that he wants to protect the family if they're a guard dog.

However, medical issues, like skin allergies or dry skin, are among the "negative" factors that may cause your dog to stay out in the rain. Even, the need for temperature regulation (excessive heat indoors), and fearfulness.

Benign Reasons Why Your Dog Stay Out in the Rain

Here are all the reasons you shouldn't be concerned about your dog sitting out in the rain and what would cause them to do so more frequently.

Your Dog Has Sensed Another Animal Outdoors

It's possible that your dog has detected other animals or dogs, and he may be intrigued about their scents, which leads him to investigate them. 

A dog who goes outside and immediately begins searching for objects and marking its territory is more likely to develop this behavior. This behavior is not directly related to the fact that it is raining outside, but will occur regardless of the weather.

He Simply Enjoys the Feeling of Rain

If the temperature isn't too cold, it's possible that your dog doesn't perceive the weather as too cold or uncomfortable, and instead prefers the sensation of rain.

If your dog has a double coat, this is more likely to happen even more if he doesn’t spend much time outside when the weather is truly cold.

He Likes to Be Outside

Some dogs are bred for the great outdoors, for this they will spend as much time as they can outside; it's simply in their genes. Despite the fact that a large number of dogs have already become extremely domesticated, each dog counts with hundreds of years of breeding history.

Dog breeds that count with double coats are especially good to be outside in cold weather. They will most likely stay outside in the rain until they feel water seeping thru their thick double coat.

Dogs Are Especially Willing to Mate When It Rains

A significant relationship has been established between the frequency and  incidence of mating-related activities in dogs and the amounts of rainfall.

Furthermore, dogs exposed to strong odors in urban areas will perceive fewer heat signals and detect fewer pheromones due to the air pollution. Rain helps to alleviate these issues by boosting the pheromones' ability to reach him. Neutering your dog can reduce this kind of behavior.

He Is Protecting Their Family

Dogs are capable of detecting impending bad weather. When it comes to guard dogs, they may have decided to stay outside to protect you from what is about to come.

Also, dogs have an innate ability to detect changes in the atmosphere's constant electric field, which is extremely useful when a large storm is approaching.

Worrying Reasons Why Your Dog Stay Out in the Rain

The following are the negative reasons why your dog may be standing out in the rain:


It's very likely that something is making your dog nervous or afraid. This problem is more common if your dog has a habit of going outside at specific times of the day or like when a specific person is present.

It’s Too Hot for Him Inside

If your dog hasn't always gone to stay in the rain, it might be worth investigating what else happened when he first started doing so. A change in the internal environment, such as a temperature change, could be the reason for the behavior change. Especially if this began almost immediately after the change.

Your dog, on the other hand, may just prefer to be outside while it’s raining to enjoy the accompanying breeze. When dogs are outside, they are more appreciative of the good temperatures on cooler days and will run about to get a better feel for the air.

When it’s really hot, most dogs eat less and become less active; thus, they become more lively and adventurous when they sense rain is on the way.

Medical issues

Other possibilities include sickness, skin allergies, dry skin problems, and other medical conditions as the root cause of the problem. This is more likely if your dog's behavior has abruptly changed and they have been exhibiting other signs of illness, such as throwing up or extreme lethargy. 

If any of this happens, taking him to the veterinarian is the best option.

Why Dogs Don't Like Rain

At the other extreme, there are pets that hate wet weather. Rain not only makes some dogs uncomfortable; many dogs are afraid of thunderstorms. Dogs are extremely sensitive, and they can often predict bad weather. Your dog may become agitated, hide, or begin biting objects.

Another reason dogs dislike rainy weather is that the rain’s sound can get amplified. It is well known that dogs have extremely sensitive hearing. Instead of enjoying the rain as us, they may find the noise distressing. Try to keep your dog entertained in this situation to make them feel relaxed and safe.

Dangers of Rainy Days for Dogs

Whether your dog enjoys rain or not, rain can cause serious health and safety issues if your dog is outside in the rain. Here are three potential hazards to be aware of:

Low Visibility

When it’s pouring, some drivers may not be able to see well and it can become a major safety risk for dogs. Rain, thunder, and lightning can frighten dogs, causing them to flee into the street, which is dangerous for both the pet and the owner.

One of the main reasons why you shouldn’t be with your dog outside in the rain is your dog's safety around cars in low visibility.


Lightning isn't the only reason to be concerned about your dog running into the street. A lightning strike, while uncommon, could damage both you and your dog.

Anything metallic, including an umbrella, could attract lightning. If you see lightning or hear thunder, seek shelter as soon as possible, and avoid high points and trees as much as possible.

You should never remove your dog's identification tags. While they're metal, the risk of your dog fleeing while scared by the storm is too great.


If dogs are exposed to cold, wet weather for an extended period of time, their respiratory system can become inflamed, potentially leading to pneumonia. This is especially true for older and younger dogs, along with those with compromised immune systems.

Coughing, wheezing or difficulty breathing, lethargy, and nasal congestion are all symptoms of pneumonia in dogs.

Dry your dog down with a blanket or towel as soon as he comes out of the rain to prevent pneumonia. You should also consider giving him a waterproof doggy raincoat before letting him out in the rain.
