This handout discusses aspergillosis in dogs, an infection, growth, or allergic response caused by the Aspergillus fungus. If your dog becomes infected, it can be confined to the nasal passages (nasal aspergillosis), or it can spread throughout the body (systemic aspergillosis). The clinical signs, diagnosis, treatment, and prognosis of both conditions are outlined.

Ataxia means incoordination within the nervous system. There are several forms of ataxia, depending upon where in the nervous system the abnormality occurs. The most common sign of ataxia is an abnormal, unsteady gait. Treatment of ataxia will be influenced by the root cause. Pain management, supportive care (such as anti-nausea medications), and creating a safe environment (e.g., preventing access to stairs) are cornerstones of ataxia treatment.

This handout summarizes atlantoaxial (AA) luxation, a condition in which instability or excessive movement is present between the first two vertebrae within the neck. Atlantoaxial luxation can be caused by trauma, hereditary factors, or a combination of these two factors. The most common sign of AA luxation is neck pain, though severely affected dogs may lose their ability to breathe due to paralysis of the diaphragm.

This handout explains atopic dermatitis (atopy) in dogs, a form of allergic skin disease brought on by an abnormal response to allergens in the environment. The clinical signs, diagnosis, and treatment are outlined.

Atovaquone is given by mouth and is used off-label to treat protozoal infections. Give as directed. Side effects are uncommon but may include stomach upset or skin rash. Do not use in pets that are pregnant. If a negative reaction occurs, contact your veterinarian as soon as possible.

Atrial fibrillation describes very rapid contractions or twitching of the heart muscle, specifically in the atria. Most of the time, atrial fibrillation in dogs occurs secondary to heart disease. In some large breed dogs, atrial fibrillation occurs as a primary heart problem. Most dogs who develop atrial fibrillation have underlying heart disease, so the signs that are observed are related to that disease and may include exercise intolerance, cough, or difficulty breathing. Treatment varies depending on whether the dog has primary or secondary atrial fibrillation. Your dog will need to be monitored on a regular basis.

The body has an immune system that protects from foreign invaders that can cause disease and infection, however, if with an autoimmune disease, the immune system attacks itself by mistake, causing illness.

Azithromycin is given by mouth or injection and is used on and off-label to treat a variety of infections. Give as directed. Common side effects include stomach upset. Do not use in pets that are sensitive to macrolide antibiotics. If a negative reaction occurs, please call your veterinary office.

Babesiosis is a tick-borne infection due to Babesia protozoal parasites. The disease primarily spreads through an infected tick's bite, but direct animal-to-animal transmission may also occur. Dogs typically present with the acute and severe form of babesiosis, characterized by abnormal dark urine, fever, weakness, pale mucous membranes, depression, swollen lymph nodes, and an enlarged spleen. The disease can be transmitted to humans through a tick bite.

Bacterial pneumonia is an inflammation of the lung, usually caused by a bacterial or viral infection, but can be caused by inhalation of an irritant. Typical signs of bacterial pneumonia include fever, difficulty breathing, lethargy, and coughing. As these can also be caused by other diseases, diagnostics include a full physical exam, blood work, and radiographs, and may also require bronchoscopy or tracheal lavage to collect samples for cytology and bacterial culture and sensitivity. Treatment includes the use of one or more antibiotics that ideally would be selected using the results of a culture. Affected dogs may also require hospitalization and supportive care including intravenous fluids. The prognosis depends on the severity of the disease and whether there are any predisposing factors.
