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.
-
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.
