Canine Influenza Information

What is canine influenza?

Influenza in dogs is a highly contagious respiratory disease. It is caused by canine influenza viruses (CIVs). The two main CIVs in circulation internationally are H3N8 andH3N2.

CIV H2N8 – First reported in greyhounds in 2001. Since then it has spread to 40 states.

CIV H3N2 – Found in March 2015. Has spread to 24 states

What are the signs of Canine Influenza?

Flu in dogs can be mild or severe.

The mild form may include:

·        Coughing that persists up to 30 days; may be moist or dry like kennel cough.

·        Lethargy

·        Low appetite

·        Fever

·        Sneezing

·        Discharge form the eyes and/or nose

Dogs with the severe form tend to have:

·        Rapid onset of signs

·        High fever (104F to 106 F)

·        Signs of pneumonia such as difficulty breathing, rapid breathing, and blood from lungs

Some dogs have died from flu related pneumonia, but the fatality rate is less than 10 percent.Most patients recover in two to three weeks.

Where can my dog catch Canine Influenza?

Canine influenza is spread via direct dog contact, a cough or sneeze (airborne), or contaminated surfaces.

The more your dog associates with other dogs, the higher the risk of contracting canine influenza or other infectious respiratory diseases. Dogs frequenting doggie day care, boarding facilities, training classes, dog parks, dog shows, or grooming facilities would be at a higher risk.

Prevention through Vaccination

Vaccines for dogs are available against both strains known to infect dogs, but they are separate vaccines; none is known to protect against both strains at once.

Initial vaccines are given once and repeated in 3 weeks. (total of 4 vaccines for the two influenza strains). Then once yearly for each influenza strain.

Does Vaccination against Canine Influenza Offer any Protection against Kennel Cough(Bordetella)?

No. These are completely different infections.
