9 Dog Skin Diseases: Comparison Chart & Medication Trea

Hello everyone, welcome to Oxygen Pet Doctor~

Summer is a peak season for canine skin diseases. Today, let's delve into the nine most common skin conditions in dogs, including ringworm, eczema, pyoderma, and mite infections. We hope pet owners can better understand how to differentiate between these conditions to avoid mismanagement.

Fungal Infection (Ringworm)

Symptoms:

Most commonly found on a dog's face, ears, limbs, and trunk.

It can lead to hair loss in the affected areas, with the hair falling out in circular patterns and spreading outward. The skin may develop scales, pustules, papules, and crusts, although often only hair loss and dandruff are present.

Treatment:

Light Infection:

● Thoroughly trim the fur around the affected skin, and disinfect with iodine.

● Apply antifungal ointment every 12 hours until the lesions heal: Dasatin (Ketoconazole Cream Compound).

Severe Infection:

● In addition to topical medications:

● Bathe the dog with Banov Bathing Lotion once or twice a week for at least 48 weeks.

● Administer oral medication: Itraconazole 510mg/kg, mixed with food and given every 24 hours.

Tip: Possible side effects include loss of appetite, nausea, abdominal pain, and elevated liver enzymes. Not to be used in animals with liver disease or pregnant animals.

● Complementary nutritional therapy: Provide highquality protein, unsaturated fatty acids, and Vitamin B.

Eczema

Symptoms:

Manifests as papules, erythema, scabs, blisters, and erosions, accompanied by symptoms like heat, pain, and itching.

Acute eczema may present as pinpoint or irregularly shaped erythematous eczema in the affected areas, with severe itching.

Subsequent phases may include papular, vesicular, pustular, and erosive stages with varying symptoms.

Treatment:

● Trim the fur around the affected skin, disinfect with iodine, and keep the area clean and dry.

● After the iodine dries, apply antiseptic ointments such as erythromycin ointment or Futan (Oxide of Zinc Ointment).

● For severe cases, oral medications like Newmei (Chlorphenamine Maleate Tablets) or dexamethasone tablets (which can effectively alleviate the itching, pain, and heat of eczema) + Vitamin B.

● If the dog's eczema develops blisters, apply cold compresses with boric acid solution and normal saline. If blisters burst, use alum solution to clean the area.

● Avoid frequent bathing of the dog, wear a head cover, and prevent scratching.

Scabies

Scabies typically affects the ends of the limbs, face, ears, abdomen, and lower abdomen of dogs.

In the early stages, there may be redness and papules, causing severe itching. After the dog chews or rubs the affected area, hair loss, bleeding, thickened skin, and yellow crust formation may occur.

Treatment:

● External deworming: Super Trustable.

● Subcutaneous or intramuscular injection of 1% ivermectin, 0.05mg/kg, once a week until cured.

● Apply 10% sulfur ointment to the affected areas once a day, for several days in a row.

● Bathing: Use 10ml of dimethoate emulsion diluted in 5 liters of water (warm water) for a bath, 510 minutes each time, every other day, for 35 times in total.

● Relieve itching symptoms: Oral Newmei (Chlorphenamine Maleate Tablets) can effectively alleviate the allergic itching caused by scabies in dogs.

● Wholehouse disinfection: Spraying insecticides in the dog's bed and the owner's home is also necessary for pest control.

● Wear a head cover: Prevent the dog from continuing to lick or scratch the affected area due to discomfort, causing secondary damage to the skin.

Demodex Mites

Demodex mites commonly affect a dog's face and ears, and can infect the entire body in severe cases.

In the initial stages, there may be hair loss and alopecia, with distinct bald patches and red bumps around the hair follicles.

In severe infections, the dog may develop a distinctive odor.

Treatment:

External deworming + oral Essoda (Cefahydroxamycin Tablets) (antiinflammatory, prevents secondary bacterial infections) + antibacterial spray + sulfur ointment + intramuscular injection of ivermectin (for severe cases) + bathing (lime sulfur suspension) + nutritional supplements to boost skin immunity.

Pyoderma

Symptoms:

Red bumps, itching, circular hair loss, pain, and fever, which may ulcerate and suppurate upon scratching.

Treatment:

Local Treatment:

● Iodine + Pipute (Terbinafine Hydrochloride Spray) + Futan (Oxide of Zinc Ointment) (twice a day).

(If there is pus, first squeeze the pus from the dog's body, disinfect with hydrogen peroxide, dry it, then soak a gauze in iodine and apply it to the affected area for more than 30 seconds to disinfect. Wait a few minutes to dry and then apply the medicine.)

Extensive Treatment:

● In addition to topical treatments:

● Bathing with麻辣洗/dimethoate, once or twice a week, for 10 minutes each time, and oral administration of cefahydroxamycin tablets/ampicillin and clavulanate potassium (antiinflammatory and antibacterial) once a day, for one week and then stop for one week.

Interdigital Dermatitis

Symptoms:

The dog's paw may become red, swollen, itchy, and painful. The dog may frequently lick or chew its paws.

In severe cases, pusfilled blisters may appear on the paw, which can lead to suppuration, bleeding, and even sepsis.

Additionally, the dog's paw may lose hair, exposing raw flesh, and the skin may become ulcerated, with grotesque flesh holes.

Treatment:

① Without Pus:

1. Trim the fur around the affected paw and clip the nails.

2. Apply iodine to disinfect the entire paw, ensuring each toe crevice is cleaned.

3. Dry it and apply Futan (Oxide of Zinc Ointment) for antibacterial and antifungal treatment.

4. Give the dog a vitamin B tablet once a day to boost immunity.

② With Pus:

1. Trim the paw fur and clip the nails first.

2. Gently puncture the pusfilled blister with a needle to drain the pus.

3. Use hydrogen peroxide to disinfect the affected area. This process can be painful, so be gentle with the dog!

4. Once the pus stops bubbling, apply iodine to disinfect the area.

5. Dry it and apply oxide of zinc ointment.

6. Severe cases may require oral administration of Essoda (Cefahydroxamycin Tablets) as prescribed by a veterinarian.

7. Give the dog a vitamin B tablet once a day to boost immunity.

Bacterial Folliculitis

Most commonly found around a dog's lips, back, lower abdomen, and inner limbs.

It can cause hair loss, itching, redness, swelling, and a large number of black spots on the skin.

Treatment:

Trim the fur around the affected area of the folliculitis.

Use a cotton ball or gauze dipped in warm normal saline to clean the chin, 23 times a day.

Apply Pipute (Terbinafine Hydrochloride Spray) to the dog's skin for antibacterial and antifungal treatment.

Then apply Dasatin (Ketoconazole Cream Compound) to the affected areas of the folliculitis.

If the folliculitis is caused by mites, additional treatment with ivermectin transdermal solution for both internal and external deworming is required.

Administer Proantin Complementary Vitamin Tablets to boost the dog's skin immunity.

Keep the diet light, avoiding longterm consumption of canned food and foods high in oil and salt.

Wear a head cover to prevent the dog from scratching or licking the affected area.

Seborrheic Dermatitis

Most commonly found on a dog's tail, and is common in German Shepherds, West Highland White Terriers, Bulldogs, and Pugs.

It is usually caused by endocrine disorders and greasy diets, and comes in two types: dry and wet.

Dry Seborrheic Dermatitis: Large amounts of silver scales, sparse coat, itching, and hair loss.

Wet Seborrheic Dermatitis: Oily scales adhering to the hair, with a large amount of oil or yellowbrown oil at the base of the tail, and a foul odor.

Treatment:

● Regularly comb the dog to remove excess oil and dandruff from the skin and fur.

● Identify and avoid environmental allergens, ventilate frequently, and clean more often.

● Wash the dog's fur and skin with Banov Bathing Lotion to reduce the oil and bacteria on the skin surface and prevent inflammation from worsening.

● For dogs with greasy, itchy, and smelly skin, systemic corticosteroids can be used, as well as prednisone 12mg/kg, once a day until symptoms improve, then gradually reduce the dose.

● Use Pipute skin spray and Dasatin (Ketoconazole Cream Compound) topically to antibacterial and antifungal, preventing secondary infection.

● Supplement Vitamin B and fatty acids to boost skin immunity.

● Keep the diet light, avoiding greasy foods and greasy dog food.

● Spend more time with the dog to reduce stress.
