There are numerous disorders that affect the whole body and create skin changes. In particular situations, the variations in the skin are attributing to the particular disease. There are instances, however, where the signs are not clearly related to the underlying cause and therefore have to be carefully distinguished from primary disorders of the skin. A number of secondary disorders are briefly described below.
Disorders affecting the skin can be associated with dietary deficiencies, particularly of minerals, fats, proteins, trace elements, and some vitamins. Nonetheless, this is quite rare in dogs that are fed on new, balanced diets. Breeds such as Siberian Huskies often require extra dietary zinc. You should consult your veterinarian so that they can advise you on your pet’s nutritional requirements. This will help you to prevent medical issues associated with dietary deficiencies.
Dermatitis is referred to as inflammation of the skin, and is occasionally seen in combination with pancreatic, liver, or kidney disorders. Elderly dogs can suffer from superficial tissue death (necrolytic dermatitis) that is a result of the diabetes and liver disease. Signs of such skin defects include fluid discharge, crusting, redness, and loss of hair on the lower legs, footpads, genitals, and face. The skin disease might actually be a precursor to the beginning of some internal disease. If there are any progressive or developing defects of the skin, then the best solution would be to have your veterinarian examine you r dog. Sometimes an early diagnosis of the disease could be the best way of ensuring successful treatment for your pet.
A comprehensive lumpy skin syndrome, which is related to kidney cysts, frequently affects German Shepherds and sometimes other breeds. Various types of skin changes can result from consuming rat poison, iodides, mercury, and ergot (a fungus found in rye). Sporadic itching with a skin rash and extensive hair loss may be exhibited by male dogs with testicular tumours. Female dogs that have not been spayed and enduring hormonal imbalances are frequently irritated, have skin rashes, frequent oestrous cycles, and enlargement of mammary tissue. The skin tumours of both conditions may start in the flank or groin region, as it progresses toward the head.
Hypothyroidism is a condition that may lead to changes in the skin, such as reduced hair growth and loss of hair. The skin becomes parched, folded, scaly, and thickened. There may also be some secondary bacterial infection, with the edges of the ears developing extensive scaling.
Hypopituitarism is a hereditary disease signified by loss of hair and short stature.
Hyperadrenocorticism, also known as Cushing’s disease, is described as an elevation in adrenal gland activity. It also leads to skin changes, for example calcium deposits in the skin, darkening of skin colour, hair loss, secondary bacterial infection, and seborrhea.
Determining the exact cause is fundamental to the treatment of all these conditions. Once the underlying causes have been verified and dealt with, only symptomatic care is required, until the primary disease is resolved.
