Why Dogs Love Lying in the Sun

Dogs love lying in the sun because it helps them produce vitamin D, increases their happiness, kills skin microorganisms, regulates temperature and energy levels, relieves joint pain, improves rest and sleep, and dries wet fur.

Vitamin D production

Sunlight helps your dog make Vitamin D. Dogs need Vitamin D for strong bones and good health. Just like people, dogs can get this from the sun. They don’t have to stay in the sun all day.

A little bit of time each day is enough. But too much sun can also hurt them, so always keep an eye on your pup when they’re outside enjoying the sunlight.

Increased happiness

Dogs love lying in the sun because it makes them happy! When dogs bask in the sunlight, their bodies produce more serotonin, which is a hormone that helps boost mood and overall happiness.

Sunbathing can turn those waggy tails into even happier ones! Not only does it feel good for them, but it also has positive effects on their mental well-being. So if you see your furry friend soaking up the sun with a big smile on their face, know that they’re enjoying some extra happiness thanks to those warm rays.

Killing of skin microorganisms

When dogs lay in the sun, the warmth and rays have a natural disinfectant effect on their skin. Sunlight helps kill harmful bacteria and microorganisms that may be present on their skin.

This can contribute to better overall skin health for dogs. So, when your furry friend enjoys sunbathing, they are not only basking in the cozy warmth but also keeping their skin clean and free from unwanted germs.

Helps regulate temperature and energy

Sunbathing also helps dogs regulate their body temperature and energy levels. The warmth from the sun can make them feel cozy and comfortable. Dogs may sunbathe to absorb the sun’s heat, which has therapeutic effects on their bodies.

It helps them stay warm when it’s chilly outside and provides a natural source of energy. Sunbathing is an instinctive behavior that allows dogs to fulfill their natural needs and preferences while keeping themselves balanced physically and mentally.

Relieves joint pain

Sunbathing can actually help relieve joint pain in dogs. The warmth from the sun can relax their muscles and soothe any tension they may be experiencing. Additionally, the heat from the sun can improve blood circulation around their joints, which may help alleviate any discomfort or inflammation.

So, if your dog is struggling with joint issues, spending some time sunbathing could provide them with some much-needed relief.

Improves rest and sleep

Sunbathing can actually improve your dog’s rest and sleep. When dogs soak up the sun, it helps regulate their body temperature, making them feel warm and cozy. This can lead to a more relaxed state, helping them unwind and sleep better at night.

The sun’s rays also influence their circadian rhythm, which is like an internal clock that controls sleep-wake cycles. So, spending time in the sun during the day can help dogs sync up with natural daylight hours and promote healthier rest patterns.

Additionally, sunlight exposure increases serotonin levels in dogs, often referred to as the “Happiness Hormone.” This boost in serotonin contributes to feelings of relaxation and contentment, making it easier for dogs to drift off into a peaceful slumber.

Dries wet fur

Sunbathing can also help to dry your dog’s wet fur after a bath or a swim. The warmth of the sun helps to evaporate any moisture trapped in their fur, leaving them feeling dry and comfortable.

It’s like a natural hairdryer for dogs! So, if your furry friend loves to take a dip in the water, letting them soak up some sun afterwards is a great way to speed up the drying process and keep them happy.

How Long Should Dogs Stay in the Sun?

Dogs should only stay in the sun for short periods of time. It’s best to avoid letting them be out during the hottest parts of the day, like midday when the sun is really strong. Instead, try to let your dog enjoy some sunlight in the early morning or evening when it’s cooler.

Every dog is different, so you need to pay attention to how they’re feeling. If your dog seems uncomfortable or starts panting a lot, it’s a sign that they’ve had enough sun and need some shade.

Remember to always provide access to shaded areas and plenty of fresh water for them to drink while they’re outside enjoying the sunshine.

Potential Risks of Too Much Sun

Excessive sun exposure can lead to dehydration, lethargy, difficulty breathing, heat stroke, and an increased risk of skin cancer and sunburn in dogs.


Dogs can become dehydrated if they spend too much time in the sun without drinking enough water. Dehydration occurs when a dog’s body loses more water than it takes in. This can happen quickly on hot days or if your dog is active while sunbathing.

Signs of dehydration include dry gums, excessive panting, loss of energy, and reduced urination. It’s important to keep your dog hydrated by providing fresh water at all times and encouraging them to drink regularly, especially when they’ve been out in the sun for a long time.


Too much sun can make dogs feel tired and lethargic. When dogs stay in the sun for long periods, their body temperature rises, putting a strain on their energy levels. Additionally, excessive exposure to sunlight can cause dehydration, which also contributes to lethargy.

Dogs may become sluggish and lack their usual enthusiasm for activities when they’ve had too much sun. It’s important to monitor your dog’s time in the sun and provide plenty of shade and water to prevent them from becoming overly tired or dehydrated.

Difficulty breathing

Dogs who spend too much time in the sun can sometimes have difficulty breathing. This is because they can become overheated, which puts strain on their respiratory system. Overheating can lead to dehydration and heat stroke, both of which can cause breathing problems for dogs.

It’s important to monitor your dog closely when they’re outside in the sun and make sure they have access to shade and plenty of water to stay hydrated. If you notice any signs of difficulty breathing, such as rapid or shallow breaths, it’s crucial to seek immediate veterinary attention.

Heat stroke

Heat stroke can be a serious risk for dogs who spend too much time in the sun. It happens when their body temperature gets dangerously high and they can’t cool down enough. Signs of heat stroke include excessive panting, drooling, weakness, vomiting, and even collapse.

Dogs with flat faces like Bulldogs are especially prone to heat stroke because they struggle to regulate their body temperature. Always make sure your dog has access to shade and plenty of water on hot days to prevent heat stroke from happening.

Skin cancer and sunburn

Too much sun exposure can be harmful to dogs and may increase the risk of skin cancer and sunburn. Just like humans, dogs can also develop skin cancers such as melanoma and squamous cell carcinoma.

Sunburn can cause painful redness, peeling, and even blisters on a dog’s exposed skin areas like the nose, ears, belly, or paws. It is important to protect your dog from excessive sunlight by providing shade and limiting their time in direct sunlight.

Applying canine-specific sunscreen on vulnerable areas can also help prevent sunburn. Regularly checking your dog’s skin for any unusual growths or changes is crucial in detecting potential issues early on.

Tips for Safely Allowing Your Dog to Sunbathe

Monitor your dog outside, providing access to shade, keeping them hydrated, applying canine sun cream, and opting for early morning or evening walks to avoid hot pavement.

Monitor them outside

Keep a close eye on your dog when they’re outside sunbathing. Make sure to monitor them so that they don’t spend too much time in the sun, which can lead to dehydration, heat stroke, and other health issues.

It’s important to ensure that your dog has access to shade where they can cool down if needed. Also, be mindful of hot pavement which can burn their paws. To keep your furry friend safe, consider taking walks in the early morning or evening when it’s cooler outside.

Remember to always prioritize your dog’s well-being and comfort while enjoying the sunshine together!

Provide access to shade

Make sure to give your dog access to a shady spot outside. Too much sun can be harmful, so it’s important for your furry friend to have a cool place to relax and take breaks from the heat.

Shade can help prevent overheating and protect their sensitive skin from sunburns. This way, they can still enjoy some time in the sunshine while staying safe and comfortable.

Keep them hydrated

To ensure your dog’s safety while they enjoy their sunbathing session, it’s important to keep them hydrated. Just like humans, dogs can become dehydrated in the heat, and this can lead to serious health issues.

Make sure you have fresh water available for your furry friend at all times. Encourage them to drink regularly by placing their water bowl nearby while they soak up the sunshine. Additionally, you can provide cooling treats such as frozen fruit or ice cubes made with broth to help keep them hydrated and cool during their sunbathing sessions.

By keeping your dog properly hydrated, you’ll promote their overall well-being and prevent any potential risks associated with excessive sun exposure.

Apply canine sun cream

To protect your dog’s skin from the harmful effects of the sun, it’s important to apply canine sun cream. Just like humans, dogs can get sunburned and develop skin cancer from excessive sun exposure.

Canine sun creams are specially formulated with safe ingredients that provide protection against UV rays. Make sure to choose a sunscreen specifically made for dogs, as human products can contain chemicals that may be toxic to them.

Apply the sunscreen to areas that are prone to burning, such as the nose, ears, and belly. Reapply every few hours, especially if your dog is swimming or sweating. By taking this simple step, you can help keep your furry friend safe while they enjoy their time in the sunshine.

Avoid hot pavement and opt for early morning or evening walks

To keep your furry friend safe during walks on hot days, it’s important to avoid walking on hot pavement. The pavement can get extremely hot and burn your dog’s paws. Instead, opt for early morning or evening walks when the pavement is cooler.

This will help prevent any discomfort or injuries to your dog’s sensitive paw pads. Remember, if it feels too hot for you to walk barefoot on the pavement, it’s definitely too hot for your pup!
