Heat Rash in Dogs: Vet-Approved Fixes for Red Spots on Belly & Underarm Rashes (2025)

Introduction

It's not just the heat that gets to us on a hot summer's day, but our fur kids - the dogs - suffer from the heat as well. Especially those dogs with delicate skin and thick hair are more prone to suffer from annoying heat rashes in the sweltering heat. Heat rashes not only make dogs itchy, but can also lead to infections that can be heartbreaking for owners.

How to Treat Heat Rash in Dogs: Soothing Red Spots & Preventing Recurrence

So, when your beloved dog develops red spots, itching and other symptoms of heat rash, how can you gently ease his pain and effectively prevent recurrence? Don't worry, this guide will provide you with thoughtful and practical solutions to keep you and your dog cool through the summer!

Heat Rash: Quickly Relieve Redness and Itching

Heat rash, as the name suggests, is an inflammatory reaction caused by hot and humid conditions that block the pores of your dog's skin and prevent sweat from escaping. Red spots, pimples, and itching are its “signature symptoms”, and in severe cases, exudates or infections may occur. Timely care and treatment is essential when your dog is in pain.

1. Cooling down first aid: give your dog a “cool place to be”

The first thing to do when you see signs of heat rash in your dog is to get him out of the heat and create a cool, comfortable place for him to “escape the heat”.

Environment: Take your dog to a cool, well-ventilated place, such as a shaded outdoor area or an air-conditioned room. Avoid exposing your dog to direct sunlight or heat sources such as ovens and radiators.

Cold compresses to stop the itching: Use a towel soaked in cold water (not too cold to avoid irritating the skin) and gently apply it to your dog's affected area. Cold compresses can quickly relieve itching and redness, allowing your dog to breathe a comfortable sigh of relief. If you have a fan or air conditioner at home, you can also turn it on to allow air circulation and accelerate cooling.

2. Topical care: Gentle care for every inch of skin

Dog's skin is more sensitive than human's. Localized care must be gentle and meticulous to avoid secondary damage.

The magic of aloe vera gel: Aloe vera is a natural “anti-itch cream” with anti-inflammatory and soothing effects. Choose pet-specific aloe vera gel or mild aloe vera cream and gently apply it to the affected area 2-3 times a day. You may want to gently comfort your dog when applying it, so that it can feel your love and care.

Warm Salt Water Cleaning: If there is exudate or pus on the affected area, it means there may be a slight infection. At this point, you can gently wash the affected area with warm salt water (½ teaspoon of salt per cup of warm water) 1-2 times a day. Warm salt water can sterilize and reduce inflammation, and help the wound to heal.

3. Medication: professional strength is indispensable

For severe heat rashes, home care alone may not be enough and veterinary help is needed.

Topical ointment: Your veterinarian may prescribe creams or sprays containing hydrocortisone to be applied to the affected area to reduce inflammation and itching. It is important to use them as prescribed to avoid abuse.

Oral medications: If the heat rash causes a secondary infection, your veterinarian may recommend antibiotics or antihistamines to control the infection and allergic reaction.

4. Preventing “self-harm”: Protecting your dog's paws

Dogs often lick or scratch to “help themselves” when they are itching, but this will only make the wound worse. Preventing self-injury is therefore a key part of care.

Elizabethan collar: This “trumpet flower” collar will stop your dog from licking the affected area, and although it may be a little aggravating for your dog, put up with it for the sake of your dog's health!

Wear a small T-shirt: If the affected area is on the body, put a loose cotton T-shirt on your dog to cover the affected area without affecting the breathability, which is a good “anti-scratching magic weapon”.

Preventing Recurrence: Keeping Heat Rash Away from Your Dog

While it's important to treat a heat rash, it's even more critical to prevent a recurrence. After all, no one wants to see their dog suffer over and over again. Here are a few practical tips to help you build a solid “heat wall” for your dog.

1. Environmental temperature control: the “cool secret” of the summer days

High temperatures are the “driving force” behind heat rashes, so keeping the environment cool is a top priority for prevention.

Reduce outdoor activity: During the hottest part of the day (usually midday to mid-afternoon), try to keep your dog indoors to avoid direct heat. Outside walks can be taken early in the morning or late in the evening when temperatures are relatively cool.

Shade and hydration: When outdoors, make sure there is adequate shade and always provide your dog with fresh drinking water. You can prepare a pet cooling pad at home so that your dog can enjoy the coolness while resting.

2. Skin cleanliness: Dryness is the best “skin care product”

A hot and humid environment is a “hotbed” for bacteria, so keeping the skin clean and dry can effectively prevent heat rash.

Focus on cleaning folds: For dogs with skin folds (e.g. Bulldogs, Shar Peis), use mild wipes (e.g. chlorhexidine wipes) to clean the folds every day to keep them dry.

Regular bathing: You can increase the frequency of bathing in the summer, but do not overdo it to avoid damaging the skin's natural protective layer. Be sure to blow-dry the coat after bathing, especially in areas with thick hair.

3. Hair management: letting the air flow freely

Long-haired dogs are more prone to heat build-up. Proper trimming of the hair can improve air circulation and reduce the incidence of heat rash.

Moderate trimming: no need to shave, just leave a thin layer of hair. This can dissipate heat and protect the skin from direct sunlight.

Regular combing: combing the hair not only removes dead skin and impurities, but also promotes blood circulation and enhances skin health.

4. Nutrition Plus: Nourishing from the inside out

A healthy diet is the cornerstone of skin health, and proper nutritional supplementation can make your dog's skin stronger.

Drink plenty of water: Make sure your dog gets enough water every day, especially in hot weather. You can add a little chicken broth or honey to the water to increase the desire to drink.

The Magic of Omega-3: Supplements rich in omega-3 fatty acids, such as fish oil, boost the skin's anti-inflammatory capabilities and reduce allergies and inflammatory reactions. Add to your dog's diet in moderation after consulting your veterinarian.

5. Dress properly: loose and breathable is the key

Clothing or accessories that are too tight can block air circulation and increase the risk of heat rash.

Choose loose clothing: If you need to dress your dog, choose breathable cotton materials that are the right size and not too tight.

Loose fitting collars: Collars should not be too tight, leave a two finger width gap to ensure your dog is comfortable.

Despite our best efforts at care and prevention, heat rashes can sometimes make a “comeback”. If your dog's heat rash doesn't improve within 24-48 hours, or if there are signs of secondary infection such as increased redness, swelling, oozing and odor, don't hesitate to take him to the vet. Leave the professional work to the professionals, and let's just give your dog a lot of love and companionship.

The summer heat is a great test for your dog. But with your care and attention, heat rash is no longer a problem. May this guide be your right hand for summer pet care, so that you and your dog can enjoy a cool, comfortable summer together. After all, seeing our dogs healthy and happy, wagging their tails, is the greatest reward we can give!

Red Spots on a Dog’s Belly: 5 Common Causes and Safe Home Remedies

As a dog lover, it's always both heartbreaking and worrisome to see red spots popping up on your furry child's abdomen. These red spots can be a minor problem or a sign of a hidden health problem. The skin on your dog's abdomen is delicate, and the appearance of red spots is often triggered by a variety of reasons, such as allergies, parasites, infections, or environmental irritants. Take it easy! This article will take you through the five most common causes of abdominal redness in dogs and share some safe, practical home remedies that will help your furry child regain his health and wag his tail again.

Common Causes of Abdominal Redness in Dogs

1. Allergic reaction: sensitive skin “protests”

Dogs, like humans, can be allergic to certain substances, and the thin skin of the abdomen is often the first place where red spots show up. Allergies are broadly categorized as follows:

Environmental allergies: Pollen, dust mites, and even household cleaners can make your dog's skin “lose its temper”. In the springtime, when pollen is scattered or the house is cleaned, the dog may scratch the abdomen and red spots will appear.

Food allergies: Some dogs are allergic to grains, chicken or beef in food, and may not only have diarrhea after eating it, but may also have red, itchy skin.

Contact allergy: When rolling on the lawn, dogs may come into contact with herbicides, fertilizers or certain irritating plants, resulting in redness and discomfort on the abdomen.

2. Parasitic infections: Big trouble from small bugs

Fleas, ticks and mites are the “invisible enemies” of your dog's skin. The bites of these parasites can cause itching and abdominal redness. Mite infestations (e.g. mange mites), in particular, can cause severe skin inflammation and even hair loss and thickening of the dog's skin. If your dog frequently scratches or chews on his abdomen, get it checked for small bugs at work.

3. Bacterial or Fungal Infections: The “Bacterial Warfare” Behind Erythema

Bacterial and fungal infections are common culprits of erythema. Bacterial infections (e.g. staphylococcus) can lead to redness, pustules, and even flaking of the skin, and your dog can become irritated by the discomfort. Fungal infections (such as ringworm) are more “sneaky” and usually present as round red spots with scaly edges, sometimes accompanied by hair loss. These infections tend to occur in dogs with weakened immune systems or are more likely to thrive in moist environments.

4. Contact dermatitis: “invisible irritation” on the ground

The dog's abdomen is close to the ground and is easily exposed to a variety of irritants, such as detergents on the carpet, plant sap on the grass, and even wet dirt. Abdominal skin is thin, the slightest stimulus may be red, itchy, and in severe cases will be red and swollen. This is especially common in dogs that like to lie on the ground or love to burrow in the grass.

5. Other causes: genetic and environmental influences

Some dogs are born with sensitive skin, such as Golden and Labrador breeds, and genetic factors make them more prone to skin problems. In addition, endocrine disorders (e.g. hypothyroidism) may also lead to fragile skin and frequent red spots. Humid environments, such as the rainy season or a kennel that is not dry for a long period of time, also provide a “breeding ground” for bacteria and fungi, which can exacerbate the problem of erythema.

Safe Home Remedies: Keep Your Dog Comfortable and at Ease

There's no need to panic too much when you notice red spots on your dog's abdomen. Here are some safe, gentle home remedies that can help relieve the symptoms and make your dog comfortable. However, it's best to consult your veterinarian before any remedy to make sure it's right for your furry child.

1. Oatmeal Bath: A Natural Soothing “Spa”

Oatmeal is nature's “skin savior,” with amazing anti-inflammatory and anti-itch properties. Prepare a small bowl of oatmeal, grind it into a fine powder, add warm water (not too hot) and stir it into a paste, then pour it into the bathtub or a large basin. Allow your dog to soak for 10-15 minutes, during which time gently massage the erythematous areas to help the oatmeal ingredients penetrate. Rinse thoroughly with water after soaking to avoid residue that can cause new irritation. Dogs usually wag their tails after the bath, as if they had enjoyed a “spa”!

2. Coconut Oil: Antibacterial and Moisturizing “All Purpose Oil”

Coconut oil is not only great for the kitchen, but also for your dog's skin. It has antibacterial and anti-inflammatory properties that can help relieve redness and itching. Take a small amount of coconut oil (food grade is best) and apply it to your dog's red spots on the abdomen 2-3 times a day, massaging gently until absorbed. Stick with it for a few days and you may notice the redness fading and your dog stops scratching so often. Be careful not to let the dog lick too much, so as not to cause gastrointestinal discomfort.

3. Aloe vera gel: a cooling and soothing “natural ointment”

Aloe vera gel is known for its cooling and anti-inflammatory properties, making it an ideal “first aid” for red spots. Choose natural, fragrance-free, color-free aloe vera gel and apply a thin layer to the red spot 1-2 times a day. Apply it gently to avoid irritating your dog's skin. Aloe vera gel not only relieves itching, but also promotes skin repair, so that your dog's belly will be smooth again soon.

4. Probiotics: Skin conditioning from the inside out

A healthy gut is the “secret weapon” of good skin. Studies have shown that intestinal problems can exacerbate allergies and skin inflammation. Adding a pet-specific probiotic supplement to your dog's diet can improve intestinal flora and boost immunity, thereby reducing skin problems. Choosing a probiotic that is appropriate for your dog's size and age, and feeding it according to the directions, may result in a gradual reduction of redness problems over time.

5. Reduce allergens: Give your dog a “clean” environment

If the erythema is caused by environmental allergies, the first priority is to reduce the allergens. Clean your home regularly to minimize dust mites, wash your dog's mattress and toys with a hypoallergenic cleaner, and avoid pollen-rich meadows when walking your dog in the spring. Consider adding an air purifier to your home to keep the air fresh. These small changes can greatly reduce your dog's risk of allergies and keep the erythema from coming back.

6. Stay dry and clean: Prevention is better than cure

Moisture is the enemy of skin problems. Dry your dog's tummy with a clean towel after every walk, especially on rainy days or after playing in the grass. Regularly cleaning the belly with a mild pet wash and keeping the skin dry will help prevent bacteria and fungus from growing. Remember to blow dry thoroughly after cleaning to avoid moisture residue.

Important Reminder: When You Must See A Veterinarian

While home remedies are gentle and effective, they are not foolproof. If your dog's erythema does not improve within 3-5 days, or if any of the following occur, take him to the veterinarian immediately:

The erythema worsens with redness, swelling, oozing or odor;
The dog is scratching frequently, resulting in broken skin or infection;
The erythema is accompanied by other symptoms, such as decreased appetite, lethargy or vomiting.

Your veterinarian may be able to identify the underlying cause of the redness through skin scrapings, blood tests, or allergy tests, and prescribe targeted medication. Don't put it off because you're hurting for money; prompt treatment can make your dog suffer less.

Erythema on a dog's abdomen is common, but most cases can be alleviated with careful observation and proper care. Whether it's giving your dog an oatmeal bath or applying natural aloe vera gel, these small gestures convey your love for your furry child. Keeping the environment clean, eating a healthy diet, and checking regularly for parasites will keep your dog's skin free of redness. If symptoms persist or worsen, don't hesitate to seek veterinary help. May your furry friend recover soon and “tell” you how happy he is with his bright eyes!

Dog Rash Under Arms: Fix Armpit Irritation with Vet-Approved Skin Care

Dogs with red rashes under their armpits are always a source of both pain and anxiety for their owners. The skin in the armpits is soft and tender, and rashes not only make the dog itchy, but may also hide deeper health problems. Friction, allergies, infections, and even hot weather can be the culprits. The good news is that with some veterinarian-approved treatments, you can help your furry child feel better and rejuvenated. In this article, we'll explain the common causes of underarm rashes in dogs and share practical, safe care tips to help your dog say goodbye to rashes and have fun!

Common Causes of Underarm Rash

1. Friction: the “invisible killer” of skin folds

Dogs have a lot of skin folds in their armpits, especially in breeds with loose skin like Bulldogs and Shar Peis, and repeated friction of the skin in the armpits during activities can easily cause rashes. Prolonged friction not only makes the skin red, but may also lead to slight breakage, laying a hidden danger for bacterial growth.

2. Allergy: “Alarm Signal” for Sensitive Bodies

Allergies are a common cause of rashes. Dogs can have allergic reactions to food (e.g. chicken, grains), pollen in the environment, dust mites, and even household cleaners. With thin skin in the armpits, allergy-induced rashes are often accompanied by itching and redness, and the dog may scratch or lick frequently and appear agitated.

3. Bacterial or Fungal Infections: Warm and Humid “Bacterial Playgrounds”

Warm and moist underarms are a “haven” for bacteria and fungi. Bacterial infections (e.g., staphylococcus) can cause rashes, pustules, and even odors, while fungal infections (e.g., Malassezia) can cause redness and flaking. These infections tend to occur in dogs with low immunity or are more likely to flare up in humid environments such as the rainy season and summer.

4. Contact dermatitis: a “direct attack” by external stimuli

Dogs rolling in the grass, drilling bushes, armpits may come into contact with herbicides, fertilizers or certain irritating plants. These substances can directly irritate the skin, causing rashes and itching. The risk of contact dermatitis is especially high in city parks or grassy areas that have just been sprayed with pesticides.

5. Heat rash: a “by-product” of hot and muggy weather

In hot and humid weather, dogs are prone to heat rashes in the armpits due to sweat buildup. Especially in some breeds with thick hair and poor heat dissipation, underarm rashes may be accompanied by slight swelling, making the dog feel uncomfortable.

Vet-approved Care: Gentle Yet Effective

Prompt and gentle care measures can go a long way toward relieving your dog's discomfort after you've noticed a red rash in his armpits. The following practical methods recommended by veterinarians are simple and easy to follow, and will also make your dog feel cared for.

1. Clean the affected area: Keeping it dry is key

Cleaning is the first step in care. Choose a mild pet-friendly lotion or fragrance-free soap and gently wash your dog's underarm rash area. Avoid products containing alcohol or harsh chemicals that may aggravate discomfort. After cleaning, pat dry with a clean towel to ensure that no moisture is left in the armpits to prevent bacteria and fungus from growing. Regular cleansing allows your dog's skin to “catch its breath” and lays the foundation for subsequent treatments.

2. Topical care: natural ingredients help

Aloe vera gel: Pure natural aloe vera gel is a “first aid weapon” for the skin, which can reduce inflammation, relieve itching and promote healing. Choose a non-alcoholic, fragrance-free product and apply it 1-2 times a day in a thin layer. Massage gently while applying to keep your dog comfortable.

Calendula Cream: Calendula is known for its anti-inflammatory and antibacterial properties, making it perfect for relieving irritation caused by rashes. Apply a small amount to the red rash 1-2 times a day for a few days to see improvement.

Oatmeal baths: The soothing properties of oatmeal are known as a “natural spa”. You can buy pet shampoo containing oatmeal, or make your own oatmeal bath: grind oatmeal into a fine powder, add warm water and stir into a paste, let your dog soak for 10 minutes and then rinse off. Dogs usually wag their tails and seem extra relaxed after the bath.

3. Medication: A “pinpoint strike” against the infection

If the rash is caused by a bacterial or fungal infection, home care may not be thorough enough. Your veterinarian may prescribe a topical cream containing chlorhexidine (antibacterial) or ketoconazole (antifungal). These medications quickly clear the infection and relieve the rash and itching. Follow your veterinarian's instructions closely when using them to avoid overdosing or interrupting treatment.

4. Probiotics: Conditioning the skin from the inside out

A healthy gut is closely related to the skin. Probiotics can balance the intestinal flora, strengthen your dog's immunity and reduce allergies and skin problems. Choose a high-quality probiotic supplement for pets and feed according to weight and veterinary recommendations. Long-term adherence may lead to a gradual reduction in your dog's rash problems and even more radiant skin.

5. Cooling treatment: a soothing summer remedy

Rashes are often accompanied by a burning sensation, and a cold compress is an easy and effective way to relieve it. Wrap an ice pack in a clean towel and gently apply it to the underarm rash for 5-10 minutes, 1-2 times a day. Or apply aloe vera gel directly to bring a cooling sensation while promoting healing. Be careful not to let the ice directly touch the skin to avoid frostbite on your dog's delicate skin.

6. Regular grooming and trimming: Prevent recurrence of rashes

Dogs with thick hair are prone to sweltering heat and humidity in the armpits, increasing the risk of rashes. Regular combing and trimming will help keep the underarms ventilated; if necessary, use pet scissors to trim the underarm hair carefully to minimize friction and moisture buildup. Trim gently to avoid hurting the skin.

7. Prevent self-injury: Protect your dog from “secondary injuries”

Dogs love to lick or scratch rashes when they are itchy, which can lead to skin breakage or worsening of the infection. Putting an Elizabethan collar on your dog or a lightweight pet T-shirt can help prevent him from “self-harming”. Choose breathable, soft materials to keep your dog safe and comfortable.

When You Must Consult Your Veterinarian

While home care is gentle and effective, some conditions require professional intervention. Take your dog to the veterinarian as soon as possible if his underarm rash shows any of the following signs:

The rash has not improved in 3-5 days, or there is oozing, crusting, or odor;
Abnormal dog behavior, such as decreased appetite, lethargy, or irritability;
Swelling, warmth or significant pain in the area of the rash.

Your veterinarian may be able to identify the root cause of the rash through skin scrapings, allergy testing, or microbial cultures and prescribe a targeted treatment plan, such as antibiotics, antifungal medications, or anti-allergy medications. Prompt medical attention can make your dog suffer less and prevent a small problem from turning into a big one.

Dog underarm rashes, while common, can be alleviated in most cases with careful care. From gentle oatmeal baths to cooling aloe vera gel, these veterinarian-approved methods will not only keep your dog comfortable, but will also give you a sense of accomplishment as an owner. Keeping the underarms dry and clean, minimizing allergens, and getting regular health checks will keep the rash away from your furry child. If the symptoms persist or worsen, don't hesitate to seek veterinary help. May your dog get rid of the rash soon and continue to accompany you in the world with those bright eyes!
