Dogs appear to be more susceptible to blastomycosis than many other species. The blastomycosis fungus seems to target the respiratory tract, although it may spread throughout the entire body. Cytology and/or histopathology are required to diagnose blastomycosis conclusively. Itraconazole is the preferred drug of treatment for most dogs. Prognosis is good for many cases of blastomycosis infection with recovery rates between 50-75%.

Dogs are exposed to botulism by eating raw meat or dead animals containing botulinum toxin produced by Clostridium botulinum. Botulism causes ascending paralysis of the nervous system. Clinical signs are reviewed as well as diagnostic tests and treatment. Prognosis is guarded depending on the amount of toxin ingested and the degree of supportive care available. There is no vaccine.

Brucellosis is a contagious bacterial infection that can cause a number of reproductive problems, including infertility and abortion in breeding dogs. Male dogs infected with brucellosis develop epididymitis, an infection of the testicle. Female dogs infected with brucellosis develop an infection of the uterus. The infection is usually diagnosed by a blood test (rapid slide agglutination test). Treatment with antibiotics is not significantly effective and infected dogs should be removed from the breeding population. In the United States, brucellosis is a reportable disease.

Campylobacteriosis is a bacterial intestinal infection usually acquired by exposure to raw meat, poultry, or infected water, but can be spread between pets and humans. Signs of infection are watery or mucoid diarrhea with straining, possible cramping, lethargy, and fever. Testing, treatment and prevention are discussed.

Candida is a type of yeast that may cause problems in the digestive tract of birds. In young birds, immunocompromised birds, or birds that have been on antibiotics for an extended period, candida may overgrow in the digestive tract and cause various problems, such as 'sour crop'.

Canine coronavirus (CCoV) is not the same virus as SARS-CoV-2, which causes COVID-19. Canine coronavirus disease, known as CCoV, is a highly infectious intestinal infection in dogs, especially puppies. CCoV does not affect people, and causes gastrointestinal problems as opposed to respiratory disease. Crowding and unsanitary conditions lead to coronavirus transmission. This article discusses signs, treatment, and vaccines for this disease.

Kennel cough is the common name for an infectious respiratory disease that affects the trachea and lower airways in dogs. Viral or bacterial pathogens may cause it. Treatment may or may not be necessary with antibiotics and, in some cases, anti-inflammatory medication. There are no long-term effects from this infection.

Canine influenza is a relatively new, highly contagious virus that causes respiratory disease in dogs. It has been reported in all US states and some Canadian provinces. Clinical signs include coughing, runny nose, and fever. Definitive testing can be performed in the early stages of the disease. Vaccination is recommended for dogs at a higher risk of infection or morbidity. The virus is not spread to humans, but cats can become infected.

Capillaria is a small internal parasite, often less than half of a centimeter in length. They are closely related to intestinal worms, though they can live in a variety of locations within the body. Diagnosis can be difficult because the eggs of Capillaria are shed only on an intermittent basis. While the parasite is easily eliminated with a dewormer, your dog may require additional medications to decrease the inflammation associated with the infection.

COVID-19 is a viral respiratory disease of humans that was first discovered in late 2019. The illness is caused by the virus SARS-CoV-2, which is a new coronavirus that has not previously been identified in humans. Certain animals can be infected by the COVID-19 virus, but it appears to be infrequent. Dogs and cats seldom show severe clinical illness if infected with COVID-19.
