Some mucoceles cause swelling of the face and neck, while others interfere with a dog's ability to swallow or breathe normally. Treatment typically requires surgical removal of the affected salivary gland(s).

Sarcoptic mange, also known as scabies, is caused by a parasitic mite that burrows just beneath the surface of the skin. The presence of the sarcoptic mite causes intense itching; an affected dog will constantly chew and scratch his skin. Sarcoptic mange is highly contagious to other dogs and humans.

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 the immune system causes inflammation that damages the sebaceous glands in the skin. Clinical signs vary between short-haired and long-haired breeds, though both experience hair loss, skin scales, and lesions that begin on the head and along the spine.

Seborrhea, also called seborrheic dermatitis, is a skin disorder in which the skin’s sebaceous glands produce an excessive amount of sebum, which is an oily, waxy substance that helps moisturize and protect the skin. The excess sebum causes scaly, flaky, itchy, and red skin. Seborrhea typically affects the back, face, and flanks and is worse in skin folds. Treatment or management depends on the cause.

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.

A seizure, also known as a convulsion or fit, is a temporary, involuntary disturbance of normal brain function. If abnormal brain activity occurs in the motor cortex of the brain, it may cause uncontrollable muscle activity. Epilepsy involves repeated seizures that may occur alone or in clusters. Seizures are one of the most frequently reported neurological conditions in dogs.

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.

Shaker syndrome is a condition that involves 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 because it responds to treatment with steroids.
