Seasonal flank alopecia is a skin condition in which affected dogs lose patches of hair seasonally, likely due to an abnormal response of the hair follicles to normal hormonal changes that occur with changing day length. This condition is purely cosmetic, so no treatment is necessary. Melatonin can be used to speed hair regrowth and prevent hair loss in dogs that develop this condition on a recurrent basis.

Sebaceous adenitis is an immune-mediated disorder in which an inflammatory process is directed against the sebaceous glands in the skin. The clinical signs vary between short-haired and long-haired breeds though both experience hair loss, skin scales, and lesions that begin on the head. Unfortunately, this disease is challenging to diagnose and treat.

Seborrhea or seborrheic dermatitis is a skin disorder in which the sebaceous glands produce an excessive amount of sebum causing scaly, flaky, itchy, and red skin. It typically affects the back, face, and flanks. It may be worse in areas with skin folds, such as the feet, neck, lips, armpits, thighs, and underside. Seborrhea can be a primary or secondary disease and is diagnosed using multiple tests to determine the underlying cause. Treatment and management depend on the cause and may include topical therapies, oral anti-inflammatories, and antibiotics.

Seizures and syncope are commonly confused with one another due to similarities in the appearance of these episodes. Both present with collapse but there are several details, explained in this handout, that can differentiate between them, which is important for determining treatment. The prognosis for each condition varies depending on the underlying causes.

Seizures are one of the most frequently reported neurological conditions in dogs. A seizure may also be referred to as a convulsion or fit and is characterized by a temporary involuntary disturbance of normal brain function, usually accompanied by uncontrollable muscle tremors or spasms. There are many causes of seizures. Once anticonvulsant medication is started, it must be given for life.

Senior dogs are in the stage of life where aging begins to affect every organ system. Some organs wear out faster or are more susceptible to cumulative damage than others, so certain observations are critical. While it is true that old age is not a disease, older dogs do merit special attention, including routine health exams twice yearly. This is important so that if your dog develops a disease, it can be recognized and treated as early as possible, thereby maintaining his quality of life for as long as possible.

Septic arthritis occurs when bacteria or another infectious agent is introduced into one or more joints, leading to painful inflammation. The signs of septic arthritis include heat, swelling, and pain in one or more joints. There is typically decreased range of motion in the affected joint(s), as well as fever, lethargy, and lack of appetite. This handout discusses causes, signs, treatment, and follow-up care.

Serotonin is a neurotransmitter produced by the body that regulates mood, sleep, body temperature, pain perception, blood vessel constriction, gastrointestinal function, and even blood clotting. An animal with serotonin syndrome experiences excessive effects of serotonin. This handout reviews the causes, diagnosis and treatment.
-
Shaker syndrome is a condition involving generalized head and body tremors in dogs. The condition is often seen in small-breed, white dogs, although dogs of any size and color may be affected. The cause is unknown but thought to be autoimmune due to its response to treatment with steroids.
-
Shar-Pei recurrent fever syndrome is a hereditary condition that affects nearly one in four Shar-Pei dogs. Affected dogs experience recurrent episodes of fever and inflammation, with no identifiable underlying cause. Inflammatory cytokines released during fever episodes contribute to the production of a protein called amyloid which is then deposited in a variety of internal organs, resulting in a condition known as amyloidosis. Signs that may accompany the fever episodes include swelling of the hocks and muzzle, abdominal pain, vomiting, and diarrhea. Non-steroidal anti-inflammatory drugs are often prescribed to reduce fever and alleviate discomfort. Colchicine is the drug of choice for the long-term treatment. Affected dogs can often be managed, but the condition will affect them for the remainder of their lives. If your dog is already showing signs of chronic kidney disease, your veterinarian will also develop a treatment plan to address the kidney disease.
