Start Here: How to Diagnose Dog Skin Problems
A veterinarian will attempt to narrow the list of possible causes by taking a thorough history along with a physical exam and diagnostic lab tests. Dog flea allergy is the leading cause of skin problems, followed by other types of allergies such as environmental dog allergies (atopy) and dog food allergy.
Mange, a parasitic condition that causes patches of baldness, is the next leading cause and is primarily seen in puppies.
Other symptoms which accompany dog skin problems such as severe hair loss and excessive panting could indicate an underlying disorder such as an endocrine disease such as hyperadrenocorticism or Cushing's Disease. Treatment for dog skin conditions involve keeping the skin clean and treating the underlying cause such as bacterial infection or parasites.
Primary vs. Secondary Canine Skin Problems
Your vet will try and determine if a dog skin problem is primary or secondary. Primary skin lesions are caused by a specific disease. Secondary dog skin issues occur when a disease progresses or from a self-injury such as itching or scratching as is common with dog skin allergy.
Identifying canine skin diseases and conditions can be difficult since there are many causes. The key to understanding which condition your dog is suffering from is to do your best to match the characteristics of each cause with the symptoms exhibited by your dog.
Symptoms and Causes of Dog Skin Diseases
Canine skin conditions vary based on shape of the lesions and condition of the skin such as crusts, scars, ulcers, or scales, and the dogs behavior such as itching. The following table describes common symptoms and causes.
Itching and Scratching, No Other Symptoms
If the skin condition is limited to dog skin itch and scratching, then the first step is to suspect the beginning of a flea infestation. It's easy to miss fleas when inspecting your dog's hair, so don't be surprised if this is the cause.
If fleas are not found after combing your dog with a flea comb, consider allergy as a possible cause. For mild conditions, ask your vet about using an antihistamine (diphenhydramine). You can also bring your dog some relief with a dog colloidal oatmeal shampoo. Avoid any product that is medicated at first, since these may cause additional irritation.
Other possible causes after fleas are ruled out are environmental allergies (called atopy), food allergy and demodectic dog mange. Mange is caused by mites and is usually seen in puppies. Symptoms include bald patches and is diagnosed by a skin scraping in the Vet's office.
When a dog's skin has a rash or is red in color and is comprised of pustules, papules (small, red circular dog skin pimples less than 1 cm in diameter) and macules, it implies that the problem is either:
Itch, Redness and Pus
In general, if your dog is suffering from skin itch, and if skin lesions are red in color and oozing pus, and are accompanied by hair loss, a trip to the veterinarian is needed as the condition is probably beyond your ability to control the problem with over the counter medications. In this case a dog skin infection has probably taken hold, requiring antibiotics and possibly short term steroid use for inflammation.
Dog pimples or acne can have multiple causes including skin tumors, allergy, infection (fungal, bacterial), fleas and mites. Some dogs can get acne with pimples around the mouth and chin. use a dab of human benzoyl peroxide to see if the condition gets better.
Dog skin pimples (papules less than 1 cm in diameter) are typically caused by:
Red spots on dog skin with a central yellow sac of pus (pustules)
Pustules are usually seen with a bacterial skin infection. Causes include:
If you see a dog skin lump do not automatically assume that is skin cancer. There are many "benign" causes of lumps or bumps such as a non-cancerous cyst, insect bite, an abscess or a benign lipoma (fat that collects under the skin.)
Dog skin tags can look like a tumor, but usually are benign will not cause any harm. The tag itself differs from a wart is that they are connected to the skin with a thin base. They are often similar in color to the skin and can sometimes be moved a bit with the fingers. In most cases dog skin tags can be left alone unless there is a cosmetic reason to remove the tag. Another reason for removal is when you have a dog that licks or scratches the area, allowing irritation and infection to take hold.
Pemphigus (skin pustles and crusts)
This is an immune system disorder where the dog's body attacks the substance that holds skin cells together. The result is the skin literally coming apart, resulting in skin pustules and crusts, particularly around the bridge of the nose and feet. Symptoms include painful skin that is very red and crusty in appearance. Commonly effected areas of immune mediated dog skin diseases are at the ear margins, lips and nasal area. Canine lupus is another immune system related disorder with similar symptoms.
There are many possible causes for dog skin odor. If the problems only occur during one time of year, then seasonal allergies are probably the cause. Bacterial and fungal Infections such as yeast can also trigger a smell, with the problem being corrected after treatment with a medicated shampoo (you can try this first) and antibiotics if needed. Other potential issues include seborrhea which also can be addressed with a shampoo. If shampoos for infection or for seborrhea not work, then visit a veterinarian for a combination of topical and antibiotic treatment.
Dogs that scratch the face, feet ,ears and arm pits usually have some form of inhalant allergy. Dog flea allergy causes dogs to scratch or lick the tail, back, groin and thigh.

Scabs or Crusts
Dog skin crusts or dog skin condition scabs are caused by the build up of pus or skin scaling due to skin diseases such as the immune-mediated disease canine pyoderma (pus filled bumps). Crusts on the ear margins can be caused by mange.
In Juvenile Pyoderma in puppies the sores form on the top of the muzzle and spread to the rest of the face.
Scratches on Rear End
Scratching near the tail could be caused by dog scooting on the ground due to a full anal gland.
Parasites (fleas, mites), poor grooming, dog skin infection (bacterial pyoderma, fungal), endocrine diseases, skin or hair follicle disorders disorders such as seborrhea, medication side effects (from corticosteroids) and allergy. It is rare for a sore or lesion to appear without another underlying condition such as allergy.
Skin Scaling (dog skin dandruff)
When the outside layer of the skin is shed, it is usually not seen on the skin and coat. Some conditions cause the flakes to accumulate.
Seborrhohea is a condition that refers to scaling and dry skin. If the skin is very greasy it is called seborrhoea oleosa.
Hyperkeratosis is a condition where the skin thickens, usually on the nose or the footpads.
Thick Dog Skin
If you see a change in dog skin thickness, it can be caused by thickening of the skin or inflammation. Causes of dog skin thickness include:
Thinning Dog Skin (cutaneous atrophy)
Dog skin that is thinning can be due to hyperadrenocorticism. Skin that suffers from cutaneous atrophy is easily wrinkled and is less elastic. It can also occur in dogs where glucocorticoids are applied as an injection or cream.
Warts (Canine papillomatosis)
Warts (papillomavirus) are non-cancerous - benign contagious dog skin pumps. They are transmitted via indirect and direct contact. Warts start as small papules and become larger to become small, cauliflower warts. They are found on the conjnctivae (eyes), buccal mucosa (lining of the cheeks and mouth), gums, tongue and lips.
The most common type are oral warts that form in the oral cavity. Warts in other places are dark, slightly raised papules and plaques. They rarely become cancerous.(9)

Common Causes of Canine Skin Disease
Flea allergy dermatitis, environmental and food allergies are the leading causes of to dog skin lesions and rashes. Even if you don't find any fleas on your dog, they are skilled at hiding, with even a few able to cause a problem in allergic dogs. Symptoms are usually in the form of raised red bumps known as hives. They are itchy and will cause your dog to scratch. Excessive scratching may break the skin, leading to infection.
If no infection occurs, hives will usually go away on their own once exposure to the allergen is removed. If infection develops, however, medical treatment will be needed. See your vet if your dog has sores that don’t go away in a few days, or sores that ooze anything yellowish in color. He may need antibiotics.
Allergy is a common cause of canine skin disease. The skin is the largest organ in the dog's body and is exposed to environmental influences such as allergens. Types of dog skin allergy include:
- Atopic Dermatitis (allergen that is inhaled causing a hypersensitivity reaction, most common cause).
- Food Allergy
- Flea Allergy
- Skin Allergy
Atopic dermatitis is a reaction to airborne allergens such as powder mites, weeks and tree pollen. It is not clear why the reaction occurs, although it is believed that there is some genetic predisposition among certain breeds(2):
- American Staffordshire Terrier
- Boston Terrier
- Bull Terrier
- Cairn Terrier
- English Bulldog
- German Shepherd
- Fox Terrier
- French Bulldog
- Golden Retriever
- Shar Pei
- Shih Tzu
- West Highland White Terrier
Triggers include air pollution, excess hygiene or stress. Allergens enter the body by swallowing, skin contact and by breathing them in.
Symptoms of atopic dermatitis are skin redness (erythema) and itch (puritus) and are usually on the abdomen, feet and face. Scratching can cause additional dog skin problems such as infection.
Treatment of atopic dermatitis skin problems on dogs starts with bathing since it helps to remove any surface allergens. The selection of shampoo should be based on what you are trying to achieve:
- Bacterial or Fungal Infection: Medicated shampoo can address infection or fungal overgrowth.
- Anti-itch: For itchy dogs, consider an anti-itch formulation that contains calming elements such as oatmeal or essential fatty acids such as All Natural Anti-Itch Shampoo.
- Anti-seborrheic shampoo: For dogs that have scaling or seborrhea (dandruff) in addition to the dermatitis. Look for a shampoo such as Duoxo with ingredients such as zinc salts, selenium disulphide, salicylic acid, sulfur or coal tar.
The veterinarian might also recommend a hypoallergenic diet that is formulated for skin and coat health. New products have been introduced that help to improve the skin layer. This includes:
- Phytosphingosin: Helps to improve the lipid composition of the skin. Found in Duoxo spray.
- Topical Essential Fatty Acids: An essential fatty acid spray can help to improve skin barrier function, reduce water loss and improve the hydro-lipidic composition of the skin.
Food Allergy Dermatitis
Food allergy in dogs causes itching on the ears and skin a few minutes, hours or even weeks (usually 24 to 72 hours)(3) after consuming an allergen. Food allergy may also make a dog susceptible to bacterial skin infection. The condition can be accompanied by nausea, increased number of bowel movements, diarrhea or vomiting.
Ingredients that commonly cause food allergy in dogs includes:
The condition is diagnosed by providing a hypoallergenic diet or elimination diet (diet of just the basics) and then seeing improvement.
Avoid treats when on this diet as they are often the cause or a cause of the dog skin problem.
Flea Allergy Dermatitis (FAD)
Flea allergy is a condition that pet parents tend to deny, even when the veterinarian makes that the diagnosis. Reasons for dogs getting fleas include:
- Dogs that come in contact with untreated animals.
- Lack of consistent treatment.
- Substitution of less effective and cheaper store bought spot-ons instead of prescription grade products.(10)
Symptoms of flea allergy dermatitis include:
- Itch and scratching on the back half of the dog.
- Crusted skin bumps (papules) in the umbilical fold
- Skin lesions (crusted papule) that have a long duration
- Symptoms in the classic areas of the body; dog has scabs on back near tail base, lower back, rear part of the dog and inner thighs.
- Itchy skin nodules
Treatment for flea hypersensitivity involves the use of prescription products that disrupt the flea lifecycle and that kill adult fleas. Goals are to kill any existing fleas and the continued prevention of fleas through the use of spot-ons, collars and oral products. New spot-on prescription products are applied to the skin every 3 to 4 weeks and are highly effective. We do not believe that over-the-counter products from pet stores provide the same level of residual activity or safety.
Demodectic dog mange is usually mold and heals on its own in 6 to 8 weeks. It could last months in localized areas on the body.(6) Studies show little difference between treated and untreated dogs for small infections that are in one area of the body. For small localized cases, therapies include using benzoyl peroxide or mupirocin massaged into the skin.
Localized cases (limited areas on the body) could cause small red hairless spots. Other symptoms can include pimples, thick skin and pus, scaling around the eyes, mouth and front legs.
For generalized cases that are all over the body the medication Amitraz, which is a monoaminooxidase inhibitor, is prescribed. It is a topical that is applied every 2 weeks.
90% of cases can be cured, but can take up to 12 months. To ensure progress is being made a veterinarian may request repeat office visits very month. Many dogs with demodectic mange also get a bacterial skin infection. For this reason an antibacterial shampoo can help to address any skin crusts.
Sarcoptic dog mange (scabies) in dogs is caused by mites. Symptoms include extreme itch, papules, scales and crusts.
The condition is diagnosed by a skin scraping, although this form of diagnosis is only positive in 30% to 50% of dogs with the condition.(7)
Treatment is with parasiticidal drugs that are administered every 2 to 3 weeks such as as a Selamectin spot-on. Other medications are ivervectin or milbemycin ,but these cannot be used in Old English Sheep dogs or Collies.
Bacterial Skin Infections
Dog bacterial skin infections are commonly referred to as:
- folliculitis (superficial pyoderma)
The infections are usually caused by the cover colonization of the skin by Staphyloccoccus. The bacteria is found on normal dog skin, but causes a problem when it grows beyond normal levels, frequently when another condition is suppressing the immune system.
This can be triggered by:
- hormonal imbalance
- kertatnization disorder
- metabolic disorders
Symptoms of a bacterial infection include:
- skin bumps
- pustules (whiteheads)
- comedones (blackheads)
Bacterial skin infections can look like Demodectic mange and Malassezia. For this reason, conditions like these need to be ruled out of a Veterinarian before reaching a definitive diagnosis.
Certain breeds such as Standard Poodles, Vizslas, Akitas and Samoyeds suffer from deep pyoderma or infection as a result of the condition sebaceous adenitis. Deep infections can also be helped by antibacterial benzoyl peroxide shampoo. The shampoo works by decreasing bacteria on the skin surface and by reducing the likelihood that an infection will return. Shampoos are used 2x per week.
All dogs suffering from skin infection will need to be re-evaluated for progress.
Folliculitis is a bacterial skin infection that causes mild to more severe skin itch. In most cases allergy is the underlying cause. Antibiotic therapy is frequently used to resolve the problem for a period of three weeks using a combination of oral and topical medications. If the condition is mild, a antibacterial shampoo or spray could be of help.
Deep pyoderma refers to cases where there is a more severe skin infection. Most cases involve hair follicles that are infected with Staphylococcal infection. Symptoms include inflammation and redness. The condition is treated for 4 to 8 weeks with antibiotics. A form of deep pyoderma that affects the skin between dog toes is called Pododermatitis. Oral antibiotics are used to treat Pododermatitis.

Calluses form when a dog consistently lies on hard surfaces. The friction between the hard surface and the skin causes thickening to occur. The most common location is a dog elbow callus, but it could also form in other areas of the body.
Treatment involves replacement of the hard surface with a softer dog bed or blanket. You can use a soothing balm or butter, but do not do this unless you also solve the problem, which is replacing the hard surface with a softer one.
Fungal Skin Infections
Dog fungal infections are also called ringworm or Dermatophytosis. Typical symptoms are hair loss, crusting and scaling in a classic circular pattern. It is less common to see symptoms such as pain, itch or skin inflammation.(8)
It is common to see a dog fungal skin infection on the forelegs (can cause spots on the feet) and face since these come into contact with the environment.
The fungus can invade hair follicles, causing hair loss or feed on the keratin in the skin itself. Dogs with a compromised immune system are at greater risk of fungal infection.
The dog skin problem is diagnosed by examining the skin under a Wood's lamp or a fungal skin culture. Treatment involves the use of topicals (azoles) that contain Ketoconazole, Itraconazole, Fluconazole or other approved medications. A veterinarian might also recommend a medicated shampoo or the use of a Lime-suflur dip used 2x per week.
All items in a household with a fungal infection patient should be cleaned thoroughly.
Dog Skin Ulcers
A dog skin ulcer is a type of wound where there is a breach in skin continuity. Since dogs have relatively thin skin, diseases that damage the skin or self-trauma results in an ulcer.(15)
There are several potential causes of skin ulcers in dogs. These skin problems in dogs include:
- Histoplasmosis: fungal infections characterized by ulceration and skin lesions.
- Leishmaniasis: nose ulcers
- Lymphoma: cancerous bumps
- Melanoma: dark lesions on older dogs
- Panniculitis: caused by skin injury or an autoimmune disorder
- Phaeohyphomycosis: contaminated wound
- Pyoderma: bacterial skin infection
- Pythosis: skin sores on legs
- Sebaceous Gland Tumors: tumors that form on the skin
- Spider bites: skin swelling after bite
Diagnosis of Canine Integumentary (Skin) Disorders
Your vet will examine your dog's skin carefully as part of a complete examination. The exam will start with a thorough history since many dog skin disorders are more common in certain breeds and at specific ages. There is also a higher incidence of specific types of dog skin problems in some breeds.
In order to properly diagnose diseases and conditions canine skin, various tests may be needed. Tests might include:
- Examining skin under a special light (a woods lights): this is done to check for certain fungal infections such as ringworm.
- Dog skin biopsy: in this test, a needle is used to remove cells from a lump to be examined by a pathologist. This can determine if a lump is cancerous or if it is just a cyst or wart.
- Blood tests: might be done to check for infections and certain nutrient deficiencies.
If you keep your dog clean and it continues to smell or have a greasy coat then your pet is probably suffering from parasites, seborrhea or a skin infection.

Skin Issues in Dogs by Breed
Dog breed can also provide some clues when it comes to skin conditions, particularly in purebred dogs. Since these dogs are bred for certain traits, they also tend to pass on the same undesirable traits, including skin disease. Disease is also passed on genetically through line or in-breeding when a small stud population is used for breeding. Dog skin problems can be limited to one litter, one breed, or could be seen across certain breeds. Some of the more common breed specific canine skin diseases and conditions are described below:
Dog Skin Disease
Belgian shepherd dogs
Canine Sebaceous adenitis:
This disease is characterized by follicular casts. The casts are skin
cell debris (keratinous debris) around the base of the hair shaft.
Other symptoms include dog hair loss (alopecia) on the top of the head,
back of the ears, at the tail and on the fore limbs.
The condition is diagnosed by examining a skin biopsy. Any diagnosis needs to differentiate (confirm the presence of this condition) vs. conditions that have similar symptoms such as leishmaniasis (infection caused by protozoa), demodicosis (a type of mange) and superficial pyoderma (dog skin infection).
Note that in the Vizsla only, a form of sebaceous adenitis, granulomatous sebaceous adenitis is found. Symptoms include localized hair loss (in a specific area on the body) and raised skin lesions,

Canine Symmetrical lupoid
onychodystrophy: This dog skin condition is characterized by the
loosening or shedding of the nails. The cause is unknown.
Other symptoms include:
Diagnosis of canine symmetrical lupoid onychodystrophy is via a biopsy, skin culture and x-rays. The x-rays can also help to determine if the condition has caused any skin infections.

Solar induced canine actinic dermatitis and squamous cell carcinoma: this condition occurs in dogs from sun exposure. As you could expect, dogs that live in sunny climates have a higher incidence of the disease.
Symptoms of actinic dermatitis appear in dog skin areas that are not protected by hair such as the abdomen and groin. Dog skin symptoms include:

The treatment of canine skin diseases and conditions depends on the exact disease or condition. Treatment may involve oral or topical medication. It may also involve removal of any lumps or bumps from your dog's skin. If your pet's skin is affected by poor nutrition, treatment will involve making a correction in the diet.
There is a myth that baths are not good for dog skin diseases and conditions. This is not correct as bathing is an important part of just about every skin treatment. Shampoos are particularly effective on bacterial and fungal infections with a medicated bath 1 - 2 times per week. They also help to remove any allergens that are caught in the dog's coat.
If a bacterial has progressed deep into the skin then antibiotics are needed. You should also carefully look at your dogs diet and if it is causing any of the canine skin problems. Follow this link to understand Dog Food for skin or sensitive skin dog food.

Treating Mild Allergic Skin Reactions
Approximately 1.2% of visits to a veterinary emergency room are for what are called mild allergic reactions. Vets refer to these as Type 1 hypersensitivity reactions. These skin reactions are triggered when skin cells called basophils and mast cells and the immunoglobulin E antibodies on the surface of those cells come in contact with an allergen. The contact can occur via injection, inhalation, ingestion or direct contact.
When the cells come in contact with the allergen they release prostaglandins, leukotrienes and histamine. In turn you start to see an allergic reaction including:
- Urticaria (skin rash)
- Pruritus (itchy skin)
- Angioedema (skin swelling, hives)
- Anaphylaxis ( a chronic life threatening allergic reaction that could result in issues with heart function and heart collapse)
Treatment usually takes one of two forms:
- Use of the medication Diphenhydramine (2 mg/kg IM once)
- Oral diphnhydramine (2 mg/kg PO every 8 hours for 2 to 3 days)
While Doctors used to prescribe a corticosteroid during the first treatment, research now shows that this is not necessary and does not improve the outcome.(16)
