Canine Influenza (dog flu) is influenza occurring in canines. Canine influenza is caused by varieties of Influenzavirus A, such as equine influenza virus H3N8, which in 2004 was discovered to cause disease in dogs. Because of the lack of previous exposure to this virus, dogs have no natural immunity to this virus. Therefore, the disease is rapidly transmitted between individual dogs. Canine influenza may be endemic in some regional dog populations of the United States. It is a disease with a high morbidity but a low mortality.
Sign and Symptoms
Like influenza viruses for other species, CIV causes flu?like illness consisting of cough, sneezing, and nasal discharge. Virtually all exposed dogs become infected; about 80% develop flu?like illness, while another 20% do not become ill. Fortunately, most dogs recover within 2 weeks without any further health complications. However, some dogs progress to pneumonia, which is usually due to secondary bacterial … Read the rest
Canine parvovirus type 2 (CPV2, colloquially parvo) is a contagious virus mainly affecting dogs. The disease is highly contagious and is spread from dog to dog by direct or indirect contact with their feces. It can be especially severe in puppies that are not protected by maternal antibodies or vaccination. It has two distinct presentations, a cardiac and intestinal form. The common signs of the intestinal form are severe vomiting and dysentery. The cardiac form causes respiratory or cardiovascular failure in young puppies. Treatment often involves veterinary hospitalization. Vaccines can prevent this infection, but mortality can reach 91% in untreated cases. Canine parvovirus will not infect humans.
Signs and Symptoms
Dogs that develop the disease show symptoms of the illness within 5 to 10 days. The symptoms include lethargy, vomiting, fever, and diarrhea (usually bloody). Diarrhea and vomiting result in dehydration and secondary infections can set in. Due to dehydration, … Read the rest
Canine minute virus is a type of virus of the family Parvoviridae that infects dogs. It is most similar to bovine parvovirus in its protein structure and DNA. A virus causing respiratory disease in humans has been called human bocavirus due to its similarity to both these viruses (bovine canine virus). Canine minute virus was originally discovered in Germany in 1967 in military dogs, although it was originally thought to not cause disease. Dogs and puppies are infected orally, and the virus is spread transplacentally to the fetuses. Symptoms are seen most commonly between the ages of one to three weeks and include severe diarrhea, difficulty breathing, and anorexia. In severe cases it is fatal.
In experimental infections, the virus is spread transplacentally when the dam is infected between 25 and 30 days of gestation and can result in abortion. When the dam is infected between 30 and 35 days, … Read the rest
