The skin is your dog’s largest organ, so it’s no wonder that it has its fair share of problems. One of the most commonly seen skin issues seen by veterinarians is rashes. Skin rashes come in all shapes, sizes and locations. Here we’ll focus on one specific area, the armpit rash.
What armpit rash is on dogs
As a pet owner, it’s natural to worry when you notice something unusual about your furry friend. One occasional issue that dogs may experience is a rash in their armpits. These rashes are uncomfortable for your pet and concerning for you. The good news is with appropriate veterinary attention, they can be easily treated. In this article, we’ll take a closer look at armpit rashes in dogs, including their causes, symptoms, and treatments. By the end, you’ll be better equipped to recognize and respond to this common condition in your own furry companion.
What are the top reasons for armpit rash on dogs?
A dog’s armpit rash can have a variety of causes, but it’s pretty easy to recognize. Behind or under your dog’s elbow (where their front leg attaches to the chest), the fur is thinner and the skin softer than in most other areas of the body. A rash is present when the skin in this area is reddened, bumpy or perhaps swollen. Rashes can also be itchy The area may be moist or greasy if infection is present, or it may be dry and flaky if caused by a chemical, plant, or allergy. Armpit rashes are limited to the area under the front leg.
1) Physical irritation: Especially when frequently wearing a harness or clothing, armpit irritation is common. The simple solution is to discontinue use of or exposure to the material, after which resolution should be quick. Dogs that are overweight and have excess skin rolls may have irritation rashes in the armpit from their skin rubbing together. Of course, the treatment is weight loss.
2) Contact dermatitis: While relatively rare, this skin reaction occurs when a dog comes into contact with an irritating substance, such as a chemical or plant. You may be able to manage it by gently washing the area with warm water and a cloth. It’s persistent, or gets worse, your pet’s best chance at quick recovery may be a visit to their veterinarian.
3) Allergies: Dogs can develop allergies to a variety of substances, including certain foods, environmental allergens, and flea bites. Allergies are increasingly common though often mild, and can cause skin inflammation and itching, which can lead to a rash. While allergies can’t be cured, and will affect your dog long term, management of a skin rash from allergies is possible with allergy and anti-inflammatory medications.
4) Grooming/ Cleanliness issues: More common in longer haired dogs than short haired dogs (though not exclusive), rashes from matting or poor grooming practices occur when a dog’s fur becomes matted and tangled or there is trapped dirt and debris in the area. These contribute to skin friction or chafing that can lead to a rash and other issues. Proper grooming is great prevention. If a problem is already present, removing the mat or cleaning the area could improve or even resolve the armpit rash within a couple of days or weeks. If a secondary infection is present, a visit to the vet is in order.

5) Fungal or bacterial infections: These can occur when bacteria or fungi enter a dog’s skin through a cut, scratch, or other skin damage. Quick recovery is likely with appropriate veterinary care.
Early symptoms to look out for
Early warning signs of an armpit rash in dogs may include redness, swelling, or itching in the armpit area. You may notice your dog scratching or licking at their armpit more than usual, or that they seem uncomfortable. In some cases, the skin in the armpit area may be warm to the touch or feel moist or greasy. If you notice any of these symptoms in your dog, keep a close eye on the area and consult with your veterinarian if the symptoms don’t improve or if you notice any other concerning changes.
Treatment options for armpit rash on dogs
While some armpit rashes require veterinary care, mild cases can potentially be managed at home with a few simple interventions.
1) Keep the area clean and dry: Clean the affected area with a gentle pet-safe cleanser and warm water, then pat it dry with a clean towel. This can help to prevent bacteria and fungi from multiplying and making the rash worse. This can also reduce physical irritants like dirt, debris, plant material, or allergens on the surface of the skin.
2) Apply a cool compress: After cleaning, apply a cool, damp cloth to the affected area.
3) Use a pet-safe anti-itch spray or cream: There are several over-the-counter anti-itch sprays and creams available for dogs that can help to relieve itching and discomfort. Choose a product that is specifically formulated for dogs and follow the instructions carefully. Because ingestion of these topical medications can be hazardous, monitor closely and apply a “”cone” (e-collar, elizabethan collar) or other device “cone” or other protective device to keep your dog from reaching the area while being treated.
