Dancing Doberman Disease This neurological syndrome is characterized by the bending of one rear limb when standing, progressing over months to include the opposite pelvic limb. The affected dog bends and extends the limbs alternatively, as in a dancing motion. A combined reaction to sensory stimulus and automatic neurological impulses is suspected in the [...]
Urethral Prolapse in Cats An out-of-place urethral mucosal lining (the mucus-producing lining of the urethral canal that carries urine out of the bladder) is commonly referred to as urethral prolapse. This condition causes mucosal lining to move to the outer portion of the urethra, vaginal, or penile opening, making it visible. Urethral prolapse [...]
Rhabdomyosarcoma in Dogs Rhabdomyosarcomas are malignant, aggressive, easily metastasizing (spreading) tumors. They arise from striated muscles (banded – not smooth, muscles of the skeletal and cardiac musculature) in adults, and from embryonic stem cells in juveniles. These tumors are often found in the larynx (voice box), the tongue, and in the heart. Aggressive and [...]
Optic Neuritis in Cats Optic neuritis is a condition in which one or both of the cat’s optic nerves are swollen, resulting in impaired visual function. The optic nerve, sometimes called the cranial nerve, is a nerve in the eye that takes visual information and transmits it to the brain. Optic neuritis affects the [...]
Hyponatremia in Dogs Hyponatremia is the clinical term given to a condition in which a dog is suffering from low concentrations of serum sodium in the blood. As a component of the extracellular fluid (fluids outside of the cells), sodium is the most abundant positive charged atom in the body. For this reason, a [...]
Excessive Weight in Cats Obesity is a nutritional disease which is defined by an excess of body fat. Cats that are over nourished, lack the ability to exercise, or that have a tendency to retain weight are at risk for becoming obese. Obesity can result in serious adverse health effects, such as reducing the [...]
Sneezing refers to the normal behavior of expelling air to remove matter through the nasal cavity. Reverse sneezing, on the other hand, refers to the reflex of bringing air into the body to remove irritants in the upper area that lies behind the nose. Dogs may gag to remove irritants from the larynx; this [...]
Lung Damage Due to Smoke Inhalation in Dogs In smoke inhalation, injury occurs as a result of direct heat damage to the upper airway and lining of the nose. Injury to the tissue is seen after inhalation of carbon monoxide, which decreases tissue oxygen delivery by binding to red blood cells; inhalation of other [...]
Squamous Cell Carcinoma of the Nasal Planum in Cats Squamous cell carcinoma is a malignant tumor of the squamous epithelial cells. In this case, it is a tumor of the nasal planum or the tissues in the nose pad. This tumor is more common in cats than dogs. Exposure to inhaled chemicals increases the [...]
Testicular Degeneration and Hypoplasia in Dogs Smaller than normal testes are generally easy to spot. There are different conditions that can lead to this disorder: underdevelopment or incomplete development of the testes is known as hypoplasia, an inability to grow and/or mature appropriately; and degeneration of the testes, which refers to the loss of [...]
