Red Rashes on Puppy's Belly: Possible Causes and Soluti

Based on the symptoms and rash location, if there is no hair loss, eczema is suspected. A diagnosis can be confirmed through skin scraping analysis and related laboratory tests.

Eczema is a condition characterized by the accumulation of dampheat and wind toxins, leading to red papules and an itchy sensation on the affected skin areas.

Causes:

Eczema can be triggered by various factors, including prolonged exposure to damp environments, unclean fur, physical or chemical irritants, or invasion by external parasites. Allergic reactions caused by these irritants can lead to eczema, particularly in dogs with thin skin and nervous temperaments.

Primary Symptoms:

This condition commonly affects areas such as under the ears, buttocks, the inner sides of the limbs, and the scrotum in male dogs. The affected skin may show red papules and blisters filled with fluid, which later crust over. Dogs may become restless and excessively scratch the affected areas, leading to frequent licking and rubbing. In the later stages, the skin may become suppurative, and in severe cases, large areas of skin necrosis can occur. When eczema occurs over a large area, it can be confused with external parasitic diseases like mange, which is primarily characterized by hair loss, a feature not present in eczema.

Prevention and Treatment:

The comprehensive approach to treating and preventing canine eczema involves identifying and removing the cause, desensitization, inflammation reduction, and treating the underlying condition.

Identify and eliminate the cause of irritation.

Administer antihistamines and tranquilizers, such as diphenhydramine (Benadryl) at a dose of 0.04 to 0.08g or chlorpheniramine at 48mg per dose, twice daily for a week. For acute eczema, intravenous calcium gluconate at 0.5 to 2g can be administered, while for chronic eczema, intramuscular hydrocortisone at 0.5% strength of 5 to 20ml can be used.

Enhance feeding management and incorporate a variety of vitamins. Switch to milk and plantbased foods, and administer vitamin A, B, and E injections or oral supplements daily.

Use hepatoprotective and choleretic drugs, such as Gan Cao (Licorice) and Yìn Chén (Indigo) or Long Dan Xie Gan decoction.

Apply topical treatments, such as hydrocortisone cream or zinc oxide ointment. For areas with erosions, apply gentian violet. For chronic eczema, apply salicylic acid or sulfur ointments.

Utilize herbal formulas that clear heat, dry dampness, and detoxify. These can be administered orally and combined with bathing for early eczema, which is effective. In cases with concurrent inflammation, antibiotics can be combined for a shorter treatment course. A sample formula includes: 20g of Gan Cao, 15g of Huang Qin (Scutellaria baicalensis), 30g of Dang Shen (Codonopsis pilosula), 15g of Gan Jiang (Dry Ginger), 10g of Huang Lian (Coptis chinensis), 10 dates, 12g of Ban Xia (Pinellia ternata), 20g of Cang Zhu (Atractylodes macrocephala), 20g of Yin Chen (Indigo), and 12g of Sheng Ma (Rhizoma cimicifugae). The decoction is divided into two doses, taken in the morning and evening. For bathing, 12g of Sheng Gan Cao and 12g of Ku Shen (Sophora flavescens) are decocted and used twice daily. Before bathing, the affected area should be cleaned with warm water to remove scabs. To prevent vomiting after medication, a subcutaneous injection of Aminophylline 4 to 10ml can be administered 15 minutes before the medication.

Treat acute eczema dermatitis with the following methods:

Administer 80,000 international units of Gentamicin intramuscularly twice daily.

Administer 5mg of Fluorometholone intramuscularly twice daily.

Apply 0.1% Rivanol saline solution topically to cleanse and disinfect the affected area, then dry and apply clotrimazole cream once daily.
