- Skin infection and Skin Care in Dogs and Puppies
Skin infection are among the most common health problems in dogs, and have many causes. The condition of a dog's skin and coat are also an important indicator of its general health. Skin disorders of dogs vary from acute, self-limiting problems to chronic or long-lasting problems requiring life-time treatment. Skin disorders may be primary or secondary (due to scratching, itch) in nature, making diagnosis complicated.
A hot spot, or acute moist dermatitis, is an acutely inflamed and infected area of skin irritation created and made worse by a dog licking and biting at itself. A hot spot can manifest and spread rapidly in a matter of hours, as secondary Staphylococcus infection causes the top layers of the skin to break down and pus becomes trapped in the hair. Hot spots can be treated with corticosteroid medications and oral or topical antibiotic applications, as well as clipping hair from around the lesion. Underlying causes include flea allergy dermatitis or other allergic skin diseases. Dogs with thick undercoats are most susceptible to developing hot spots.
Infectious skin diseases of dogs include contagious and non-contagious infections or infestations. Contagious infections include parasitic, bacterial, fungal and viral skin diseases.
One of the most common contagious parasitic skin diseases is Sarcoptic mange (scabies). Another is mange caused by Demodex mites (Demodicosis), though this form of mange is not contagious. Another contagious infestation is caused by a mite, Cheyletiella. Dogs can be infested with contagious lice.Other ectoparasites, including flea and tick infestations are not considered directly contagious but are acquired from an environment where other infested hosts have established the parasite's life cycle.
Ringworm is a fungal skin infection and is more common in puppies than in adult dogs.
Dog with dermatitis caused by Malassezia (yeast).
Non-contagious skin infections can result when normal bacterial or fungal skin flora is allowed to proliferate and cause skin disease. Common examples in dogs include Staphylococcus intermedius pyoderma, and Malassezia dermatitis caused by overgrowth of Malassezia pachydermatis.
Vitamins are one of many of the nutritional factors that change the outward appearance of a dog. The fat soluble vitamins A and E play a critical role in maintaining skin health. Vitamin A, which can also be supplemented as beta-carotene, prevents the deterioration of epithelial tissues associated with chronic skin diseases and aging.A deficiency in vitamin A can lead to scaly of skin and other dermatitis-related issues like alopecia.
Vitamin E is an antioxidant. Vitamin E neutralizes free radicals that accumulate in highly proliferative cells like skin and prevent the deterioration of fibrous tissue caused by these ionized molecules. There are also a couple of water-soluble vitamins that contribute to skin health. Riboflavin (B2) is a cofactor to the metabolism of carbohydrates and when deficient in the diet leads to cracked, brittle skin.Biotin (B7) is another B vitamin that, when deficient, leads to alopecia.
Minerals
Minerals have many roles in the body, which include acting as beneficial antioxidants. Selenium is an essential nutrient, that should be present in trace amounts in the diet. Like other antioxidants, selenium acts as a cofactor to neutralize free radicals.Other minerals act as essential cofactors to biological processes relating to skin health. Zinc plays a crucial role in protein synthesis, which aids in maintaining elasticity of skin. By including zinc in the diet it will not only aid in the development of collagen and wound healing, but it will also prevent the skin from becoming dry and flaky.
Copper is involved in multiple enzymatic pathways.
In dogs, a deficiency in copper results in incomplete keratinization leading to dry skin and hypopigmentation.The complicated combination of trace minerals in the diet are a key component of skin health and a part of a complete and balanced diet.
