Dog Influenza is a contagious respiratory disease in dogs. The mortality rate of this deadly flu may be as high as 8%, and it has caused more than 100 seal pups in the northeastern United States to die of pneumonia and may threaten human health. Scientists believe that this H3N8 (H for outer membrane hemagglutinin and N for neuraminidase) dog flu was mutated from horses five years ago and transmitted to dogs, which can attack human nasal proteins and human upper respiratory tract mucosa. It is known that H3N8 attacks a protein SAα-2,6 in the human respiratory tract. This receptor (receptor protein) is the same as the CD4 protein attacked by HIV.

Symptoms of Dog Influenza

Canine flu symptoms are similar to kennel cough symptoms. Dogs infected with canine flu virus may develop two different syndromes:

Mild type. Dogs will cough for a long time, usually wet cough, the symptoms will last 10-30 days, may be longer. During this period, the dog will experience anorexia, drowsiness, fever, runny nose, drooling, decreased appetite.

Severe type. Dogs will have a fever of more than 40 degC. Canine flu virus will affect the capillaries in the dog’s lungs. Dogs may cough up blood and have difficulty breathing. There may also be secondary bacterial infections, including bacterial pneumonia, which can make the condition worse.

Canine flu is not seasonal, and infections can occur throughout the year. Once a dog is infected, 80% will have obvious symptoms, and the rest will not have obvious symptoms. There are many pathogens that cause a dog’s “cold”. In addition to canine flu, canine distemper, parainfluenza, adenovirus type II and other bacteria and bacteria such as Bordetella and mycoplasma can cause dogs to sneeze and runny nose. Therefore, it is best for the owner to take the dog to the hospital to check for pathogens, so that the medicine can be administered as soon as possible.

Precaution of Dog Influenza

Be cautious in Dog Coughing: The initial symptom of a dog after being infected with the virus is coughing, which may later develop into pneumonia, sometimes with fatal complications.

Wide spread: The University of Florida immunologist Sinda Crawford said that dog flu is easier to spread among dogs in captivity, but it may also spread in public places such as the street, and the dog sniffs on the street. , Sharing the same water tray may cause infection. In addition to being able to spread between dogs, the virus may also spread to people who have been in contact with sick dogs. So it is better for dog owner to clean and disinfect the dogs bowl and other supplies, and avoiding contact with sick dogs when going out.

Viruses are highly Contagious: Because dogs are so virally contagious, when dog owners bring pet dogs who cough constantly to come to the clinic, Katz has to take some sort of isolation, or have these sick dogs wait outside the clinic, or Stay far away in a corner of the clinic. All areas where sick dogs come into contact must be disinfected.
