Spondylosis deformans is a condition that affects the vertebral bones of the spine and is characterized by the presence of bony spurs or osteophytes along the edges of the bones of the spine. Spondylosis deformans is a chronic condition that is associated with aging and most dogs are free of symptoms. This condition is usually diagnosed from radiographs of the spine. Treatment recommendations depend on the individual dog and whether they are showing any clinical signs such as pain and difficulty with movement.

Staph (or staphylococcal) dermatitis is an inflammatory skin condition that the skin caused by a group of bacteria called Staphylococcus. Any disorder that causes itching or a change in the skin’s environment can create the ideal conditions to allow Staphylococcus to become a problem. This handout discusses Staphylococcus dermatitis in dogs, as well as a hypersensitivity (allergic) reaction to this bacteria. The clinical signs of these conditions, along with diagnosis, treatment, and prognosis, are outlined.

Strokes are rare in dogs. Some causes include a blood clot such as a thrombus or embolus that lodges in a cerebral blood vessel, cerebral bleeding from trauma, or a blood clotting disorder; however, the cause is often unknown. Signs of a stroke are variable depending on the regions of the brain affected and the degree and duration of blood and oxygen deprivation. Magnetic resonance imaging is the ideal diagnostic test for diagnosing a stroke. Treatment is complex and there is no guarantee of complete success. Your veterinarian will help you assess progress and plan remedial action.

Struvite bladder stones are one of the more common bladder stones found in dogs. Struvite bladder stones usually form as a complication of a bladder infection caused by bacteria, and if the urine becomes exceptionally concentrated and acidic. The most common signs that a dog has bladder stones are blood in the urine (hematuria) and straining to urinate (dysuria). There are three primary treatment strategies for struvite bladder stones: 1) feeding a special diet to dissolve the stone(s), 2) non-surgical removal by urohydropropulsion (flushing out the stones) and 3) surgical removal. Dogs that have experienced struvite bladder stones will often be fed a therapeutic diet for life.

Stud tail, or tail gland hyperplasia, is a condition in which the oil glands near the base of the tail enlarge. This condition causes hair loss, excess accumulation of oils in the skin and on the fur, plugged hair follicles, and secondary infections. It is most common in intact male dogs, as these glands are under hormonal control, but any dog can be affected. Other hormonal imbalances and skin disorders can also cause this problem. Prognosis is generally good, especially if the underlying cause can be identified and controlled.

Sudden acquired retinal degeneration syndrome (SARDS) causes blindness in older dogs, most often females. The underlying cause of SARDS is unknown and there is no effective treatment for the condition. This handout explains the clinical signs observed in affected dogs, how the condition is diagnosed, and how to support a dog with SARDS.

Syncope (or fainting) is defined as a temporary loss of consciousness that occurs when the brain does not receive enough oxygen. Most dogs who experience syncope spontaneously recover once appropriate levels of oxygen reach the brain.

This handout explains syringomyelia and Chiari-like malformation in dogs, in which fluid-filled cavities in the spinal cord develop, leading to an abnormal sensation in affected dogs. The clinical signs of the condition, along with diagnosis, treatment, and prognosis, are described.

Systemic hypertension describes high blood pressure throughout the entire body. Hypertension in dogs is often due to an underlying disease (secondary hypertension). When there is no underlying disease, it is called primary hypertension. There are several signs of hypertension including sudden blindness, bleeding inside the globe of the eye, persistently dilated pupils, head tilt, seizures, disorientation, ataxia, circling, weakness or partial paralysis, nystagmus, increased drinking and urinating with the progression of chronic kidney disease, hematuria, and epistaxis. The treatment of dogs with hypertension depends upon the underlying cause. Medications commonly used to manage hypertension in dogs include angiotensin converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists (ARBs), beta blockers, diuretics, and calcium channel blockers. The course of hypertension in dogs depends on the underlying cause.
