Diagnosis and Treatment of Pyoderma in Dogs

Deep bacterial pyoderma is a bacterial infection involving the deep layers of the skin; the dermis and sometimes the subcutaneous tissue.  It usually starts as a superficial infection of the hair follicle (folliculitis) that breaks through the follicular wall into the dermis.  The resulting inflammation and infection of the dermis is called furunculosis.  When the […] Read more>

Hypothyroidism in Dogs: Causes, Diagnosis, & Treatment

Causes of Hypothyroidism in Dogs Hypothyroidism, an under production of thyroid hormone, is reported to be the most common hormonal disease in dogs. It may affect any breed as well as mixed breed dogs.  Golden retrievers, Doberman pinschers and Labrador retrievers appear to be at an increased risk of developing the disease.   Typically, one sees […] Read more>

Iatrogenic Hyperadrenocorticism in Dogs (Cushing’s Syndrome)

Hyperadrenocorticism in dogs may occur spontaneously or may be iatrogenic from the administration of glucocorticoids (GC) like prednisone (a steroid). Spontaneous hyperadrenocorticism is pituitary dependent (most commonly a pituitary gland adenoma producing ACTH hormone that signals the adrenal gland to produce cortisol hormone without feedback regulation) or adrenal dependent from an adrenal tumor (tumor produces […] Read more>

Alopecia X in Dogs (Hair Cycle Arrest)

Alopecia X is a name given to a skin condition in the dog resulting in non-inflammatory hair loss. Other names used for the same condition have included adrenal sex hormone imbalance, wooly syndrome, coat funk, black skin disease, pseudo-cushings, and follicular growth dysfunction of plush coated breeds. I now call this alopecic condition hair cycle […] Read more>

Feline Hyperadrenocorticism (Cushing’s Syndrome)

Feline hyperadrenocorticism (HAC) is a rare condition in cats. Spontaneous HAC is associated with increased production of endogenous steroid hormone (cortisol) by the adrenal cortex. 75-80% of cases are pituitary dependent (functional pituitary adenoma) and 25% are caused by an adrenal tumor (carcinoma or microadenoma). Feline HAC may also be iatrogenic from exogenous use of […] Read more>

Treatment for Calcinosis Cutis in Dogs

Calcinosis cutis (CC) is the deposition of inorganic, insoluble mineral salts into the different layers of the skin. It is characterized histologically (under the microscope in tissue samples) by mineralization of dermal collagen fibers, accumulation of macrophages and mixed inflammatory infiltrates, acanthosis (thickening of skin), ulceration and evidence of elimination of mineral through the skin. […] Read more>

Feline Allergy: Eosinophilic Granuloma Complex

Eosinophilic plaques, granulomas, and ulcers are lesion types that make up the entity of Feline Eosinophilic Granuloma complex. This group of inflammatory lesions, usually associated with an underlying hypersensitivity to fleas (flea allergy), food components (food allergy), or environmental allergens (feline atopic dermatitis) is common in cats. Eosinophilic plaques appear as one or few red, […] Read more>

Genodermatoses – Genetic Skin Diseases

The term “genodermatoses” applies to skin conditions of genetic origin. Genodermatoses are most often congenital (present at birth), but appearance may be delayed. Additionally, Genodermatoses may be hereditary or due to some influence during gestation, even up to the moment of birth.   Genodermatoses – Genetic Skin Diseases DERMATOMYOSITIS Familial canine dermatomyositis is a hereditary […] Read more>

MDR1 Genetic Testing in Dogs

MDR-1 (ABCB1) genetic testing for the defect that confers ivermectin hypersensitivity in Collies and other breeds Collies, their crosses, other herding breeds, and other mixed breed dogs may possess a mutation in a gene that produces the protein, P-glycoprotein. P-glycoprotein is the product of the multi-drug resistance gene MDR-1. The functional protein plays an important […] Read more>
