"Dog skin pimples are actually a blockage of the skin's sebaceous and sweat pores. These pores are responsible for the release of sebum – oily secretions, which keeps the skin surface free of dandruff. Dandruff or drying skin can lead to the death of epithelial dermal tissues (outer layer of the skin), scaling and hardening of the skin. This is also known as the thermoregulatory activity of skin, with help of the sweat glands. These pores once blocked due to any reason e.g. allergy, parasitic infestation, fungal or bacterial infection can cause the accumulation of dead tissues, sebum and sweat under the skin pores, particularly at the base of hair follicle. This accumulation appears as a pimple on a dog’s skin. These dog skin pimples can appear anywhere on the skin and may be itchy, painful, and appear as pustules. Diagnosis is only possible once these pimples mature and appears on the skin surface. Treatment involves the use of different anti–allergy drugs combined with antibiotics and NSAIDS."
Canine skin pimples are a blockage of skin pores. These pores are responsible for secreting not only the required amount of oils to prevent scaling and drying of skin, but also they help in excreting excessive water, thermoregulation and for maintaining skin dampness. Factors which can block skin pores result in the accumulation of all of the secretions and excretions under the skin surface, which on maturity appear as a dog skin pimple.
Canine skin pimples may be diagnosed and differentiated with a physical examination and by taking a history of the condition. Different techniques such as an examination of skin scrapings for parasitic causes, culturing, the isolation of Staphylococcus species for bacterial invasion, and serum & hypersensitivity tests for allergy detection can be helpful. Examination of the contents of the pimples may reveal antibodies for a specific antigenic matter.
Skin pimples on dogs should be differentiated from several other types of skin lesions. The blockage of skin pores usually is found at the base of the hair follicle.
Treatment should only be initiated once the cause of the canine skin pimples is confirmed. Systemic administration of several drugs can lead to a positive result, only if the localized treatment plans are effective.
Parasitic infestations can be treated by a dip of amitraz or an over the counter lime-sulfur dip such as Naturasil. A mites’ infestation can also be treated with Ivermectin, Selamectin & Melbemycin.
Shampooing is another option. Medicated shampoos containing repellents for mites and fleas are usually effective in treating dog skin pimples.
Bacterial infections can be treated with broad spectrum anti-biotic therapy. Penicillin at a dose of 10000 – 50000 IU/Kg (Intra Muscular IM Injections) and first generation cephalosporin’s like cephalexin at 22 mg/Kg per oral doses are considered to be an effective approach for staphylococcal species that cause skin pimples in dogs.
