This came specifically from California, but this illness spreads rapidly, so it may move across the country soon. Current Outbreak of Canine Influenza H3N2 cases in Los Angeles County July - October 2021 - Outbreak in dogs throughout Los Angeles County Between July and October 2021, approximately 800 confirmed and suspect cases of CIV H3N2 in dogs in LA County have been reported to Veterinary Public Health. Sadly, 7 deaths in dogs have been associated with this outbreak. Of the cases reported, most were associated with attending boarding kennels or dog daycare settings. There are a number of cases that have never visited a boarding or daycare facility, but were exposed while on walks in their neighborhood, at dog parks, groomers, or at veterinary clinics. This virus has spread rapidly among dogs throughout LA County, affecting many congregate facilities. Based on interviews with these facilities, many additional cases have not yet been reported to VPH. We suspect that this outbreak likely involves more than 1000 cases of CIV H3N2 in LA County dogs. Dogs that appear to have 'kennel cough' have a high likelihood of having CIV H3N2. To date, this is the largest outbreak of CIV H3N2 ever reported in LA County. To stop the spread of this outbreak, pet owners and veterinarians are strongly encouraged to vaccinate dogs against CIV H3N2 and isolate sick pets at home for 28 days from the first day of illness. Pets exposed to confirmed or suspected cases should be kept on a home quarantine and observed for clinical signs for 14 days. Recommendations Pet owners If your pet has symptoms of influenza, keep it away from other animals and contact your veterinarian. Symptoms of influenza may include: cough, fever, sneezing, discharge from the nose, lethargy, and/or loss of appetite. Some dogs have no symptoms. Vaccinate dogs against CIV H3N2 before they enter boarding kennels, dog day care, dog parks, or engage in dog group activities. This vaccination is also advisable for dogs that may occasionally encounter other dogs. The CIV vaccine is two doses, given 3-4 weeks apart. To provide time for immunity to develop, dogs should wait 2 weeks after receiving the second dose of the vaccine before entering facilities or having contact with other dogs. If your pet is sick, keep your pet at home for 28 days from the first day of illness - this will help to prevent your dog from spreading the disease to other dogs even after they are fully recovered. If your pet is asymptomatic but was exposed to other sick pets, keep your pet at home for 14 days to monitor for symptoms and then contact your vet if they become ill. To prevent spread of disease, do not let a sick pet share its food bowl, leash, toys, or other supplies with other pets. Wash your hands after touching your pet.
