Canine and Feline Estrogen Excess
Estrogen excess happens when the ovaries overproduce estrogen or estrogen is given in excess, leading to symmetric hair loss, skin changes, and reproductive-tract problems. It is corrected by stopping the source and, in tumor cases, surgical removal.

Testicular Tumors in Dogs and Cats
Testicular tumors are among the more common tumors in older dogs and are rare in cats. They often cause feminization from excess estrogen, including attraction from other males and symmetrical hair loss. Surgical removal of the affected testicle is the standard treatment, and neutering prevents the disease.
What causes dark skin on a dog’s lower abdomen and groin?
Darkening of the skin on a dog's lower abdomen and groin can have several causes. These include normal pigmentation, skin disease, endocrine disorders, and staining from friction or urine.

How to Handle Milk Engorgement in Nursing Dogs
Milk engorgement in lactating dogs is common and, when mild, can be eased by adjusting the diet and gently massaging or warm-compressing the mammary glands. Severe casesโespecially those involving mastitisโrequire prompt veterinary attention, often with antibiotics and manual milk drainage. Preventive care centers on balanced feeding, moderate exercise, and stress reduction.
What Causes Hormonal Hair Loss in Cats
Hormonal (endocrine) hair loss in cats shows as symmetric thinning, often on the abdomen. It stems from cortisol, sex, thyroid, or growth-hormone imbalances. Treatment targets the underlying disease plus hormone management through medication and diet.

Sertoli Cell Tumors in Dogs and Cats
Sertoli cell tumors are hormone-producing testicular tumors of older male dogs and cats that cause feminization through excess estrogen. Signs include symmetrical hair loss, enlarged breasts, and a lengthened prepuce. Surgical removal of both testicles resolves most signs within a few months.

Male Dog Feminization Syndrome
Feminization syndrome in male dogs is caused by a testicular (Sertoli cell) tumor or excess estrogen medication, producing enlarged breasts, milk flow, and attraction of other males. Surgical removal of the affected testicle is the main treatment.

Ovarian Cysts in Dogs and Cats
Ovarian cysts in dogs and cats arise from unruptured follicles or corpora lutea due to endocrine imbalance. Follicular cysts cause constant estrus and excitability, while luteal cysts cause prolonged anestrus; medical therapy is tried first, with ovariectomy if it fails.

Vaginal Hyperplasia in Dogs
Vaginal hyperplasia is a proliferative swelling of the vaginal wall in female dogs, usually during estrus, driven by excess estrogen response. Small masses often resolve after estrus, but protruding masses that are abraded or infected require surgical removal.
