Canine Influenza Virus

Berkeley Dog and Cat Hospital would like to keep you up to date about the Canine Influenza Virus and your dog’s potential risk. The Bay Area has been impacted by the Canine Influenza Virus (CiV) since 2018; cases are still reported regularly. To date, there is no evidence that the canine influenza virus is transmittable to humans.

Similar to the human flu, the canine influenza virus is highly contagious and is spread through close contact with an infected dog. The infected dog is typically spreading the virus during the incubation period (day 2-4) before they become symptomatic around day 5. The symptoms are respiratory in nature and can vary from one case to another. Some dogs can have mild symptoms such as a fever, runny nose, lethargy, and a cough. Others have become severely ill with life threatening symptoms such as pneumonia.

Since the virus is contagious through close inter-dog contact clients should consider the vaccine especially if their dog frequents doggie day cares, dog parks, boarding facilities, groomers, or anywhere else they may have close interaction with other dogs.

We have a supply of the vaccine that provides protection against both the H3N8 and H3N2 Canine Influenza strains that we are seeing in the reported cases. We urge you to consider vaccinating your dog if you feel your dog may be at risk. An appointment with one of our daytime general practice doctors can be made by calling Berkeley Dog and Cat Hospital. Your dog will be vaccinated at the time of this doctor appointment and will need to return for a booster vaccination 3-4 weeks later. The booster vaccine can be scheduled as a technician appointment. If Berkeley Dog and Cat Hospital is not your primary veterinarian, then contact your hospital for their policies.

Canine Flu Vaccine BD&C protocol change as of May 21, 2018

  • The Flu epidemic in the Bay Area has seemed to have passed. The last recorded Flu positive case in the Bay Area was reported in March. Therefore, we are changing our policy for boarding at BD&C.
  • We are now RECOMMENDING the Canine Influenza Vaccination for boarding dogs, but it is NOT REQUIRED.
  • With the support of our clients and their respect to keep our boarding facility free from diseases, we did not have any problems with dogs exposed to the flu virus in our boarding facility. Thank you to our wonderful clientele for their compliance during the flu epidemic.
  • We did see two cases here that were flu positive after boarding in a facility in SF and the staff took all precautions to not expose our hospital or any other patients to these two dogs.
