Dermatitis in Dogs: Symptoms & Treatment

Dog dermatitis is frequently diagnosed, but what does it mean? Here are some facts concerning this category of skin disorders, along with potential signs and remedies. In dogs, dermatitis refers to a range of conditions that result in irritated, frequently itchy skin.

Signs and Symptoms of Dermatitis in Dogs

Dog dermatitis frequently manifests as excessive licking or biting, itching, and scratching. Bacterial secondary infections can result in dermatitis. A little irritation could be the beginning of a skin condition, but as the dog licks, chews, and scratches, the skin becomes more exposed to microorganisms. Pimple-like little pimples that erupt, break, and cause crusting and scaling.

The affected area may become uncomfortable and leak fluid if the issue spreads to deeper layers of the skin. It might even fall off, dead skin.

When an inflammatory response persists, the skin thickens and darkens. It can start to look scaly, leak more fluid, or smell bad.  Among other symptoms, pus-filled blisters, scabs, and hair loss can be observed in dogs with dermatitis.

Causes of Different Kinds of Dermatitis in Dogs

Given the wide range of ailments that go under the umbrella term “dermatitis,” there are a plethora of potential causes. These include contact irritants, burns, trauma, allergies, including atopic dermatitis and food sensitivities, and systemic diseases, which are illnesses that impact the entire body. Dermatitis can also result from infections, which can be brought on by fungus, viruses, bacteria, or external parasites like fleas or mites.

Dogs’ Hot Spots

Hot spots, also known as pyotraumatic dermatitis, typically arise from underlying conditions that incite a dog to scratch and chew, such as flea bites or pyoderma. The term “hot” refers to how quickly the lesion worsens due to the openings that are created by scratching and the moist environment that is created by chewing.

Dogs with ear mites

Ear mites are a sort of tiny bug that is extremely contagious. Ear mites, as their name implies, typically appear in the ears of dogs, particularly pups.

Dogs with Malassezia Dermatitis

Dog skin already contains a form of yeast known as Malassezia yeast. However, excessive production might cause canine yeast dermatitis and irritate your dog’s skin.

Dogs with Pyoderma

Canine pyoderma is a bacterial skin condition with multiple major types. Skin fold (or surface) pyoderma is a condition that causes moist skin folds or wrinkles. It is commonly caused by the bacteria Staphylococcus pseudintermedius. In patients with superficial pyoderma, the infection has spread slightly farther. Once the infection reaches the skin layer nearest the dog’s muscle, deep pyoderma develops.

Dogs with Mange

Dog mange is a skin disorder brought on by mites. Dogs can get demodectic mange or sarcoptic mange, which is also referred to as canine scabies. When Demodex mites, which typically reside on your dog’s skin, proliferate unchecked in hair follicles, it can lead to demodicosis, also known as demodectic mange. On the other hand, a mite known as Sarcoptes scabies spreads from host to host and causes the extremely contagious disease known as sarcoptic mange in dogs.

Dogs with Seborrheic Dermatitis

When seborrhea occurs, the skin’s outer layer regenerates unusually quickly. In dogs, secondary seborrhea is caused by underlying medical diseases (such as allergies or hormone issues), whereas primary seborrhea is inherited

Walking Dogs With Dandruff

Cheyletiella mites also referred to as walking dandruff, are infectious and can survive on a dog for up to ten days. Tiny, moving white dots will be visible on your dog’s trunk and back.

Dog Skin Allergies

The most prevalent kind of allergic reaction in dogs is skin allergies, sometimes referred to as allergic dermatitis. They are frequently brought on by allergies to food, environment, or flea bites (atopic dermatitis).

Diagnosing Dermatitis in Dogs

After obtaining your dog’s medical history, your veterinarian will inspect and assess your dog’s symptoms. This will assist in identifying the sort of dermatitis your dog might be suffering from. Your veterinarian can examine flea bites on your dog to determine whether your pet has flea allergies, for example.

Your veterinarian will frequently remove the discharge or do skin scrapings. The veterinarian will look under a microscope at these samples after they are obtained to check for yeast, parasites, mites, or other organisms.

Your vet will identify any underlying causes if there are any. This could entail testing with blood or other substances. To determine environmental allergies, for instance, your veterinarian might do an intradermal skin test. Your dog’s diet may be altered to detect food sensitivities.

Dog Dermatitis Treatment

The ultimate goal of treating dermatitis in dogs is to identify the underlying cause of the skin inflammation. Treating the particular signs and symptoms of your dog’s skin disease is also necessary to keep them from hurting themselves any further.

Your veterinarian may recommend antihistamines, steroids, or other oral drugs to relieve itching. They might also supplement your dog’s diet with fatty acids. Applying topical anti-itch sprays might lessen discomfort. The use of a recovery collar helps stop chewing and scratching-related infections from spreading.

Your veterinarian will recommend both oral and topical antifungals if yeast is the root cause. Using shampoos that contain benzoyl peroxide, selenium disulfide, or other items that are meant to get rid of scale and grease may be advised by your veterinarian. Additionally, they might recommend a dog shampoo with miconazole, ketoconazole, or chlorhexidine as an antifungal.

Oral antibiotics may be prescribed by your veterinarian if bacteria are the problem. They’ll probably advise routine washing with a gentle antibacterial or antimicrobial shampoo and soothing sensitive skin with an oatmeal-based dog shampoo. It’s critical to completely dry your dog after bathing them. A moist environment serves as a haven for germs and fungi.

Your veterinarian will probably suggest topical and oral treatments meant to eradicate any mites or fleas that may be present. Use the flea treatment that your veterinarian recommends for your dog if it has a flea allergy, and remember to add a flea and tick preventative to help prevent re-infestation.

Since mites can be difficult to locate, your veterinarian may handle suspected instances in the same manner as confirmed cases. Both topical treatments like miticidal shampoo and oral drugs like antibiotics and antihistamines are likely to be recommended by your veterinarian. You should wash every piece of dog bedding several times. Use dog-safe insecticidal sprays to treat the surroundings, and be sure to sanitize grooming supplies.

Your dog’s veterinarian might recommend a veterinary dermatologist if needed.
