The Los Angeles County Veterinary Public Health is investigating a rapidly spreading outbreak of canine influenza H3N2 (CIV H3N2) in local dogs. This is an infectious and vaccine preventable respiratory disease that can spread rapidly in unvaccinated dogs. More information on this outbreak can be found on their website at LA County Vet Public Health Dept.

Doggy day cares, dog parks and boarding kennels face increased risk of spreading disease due to the close interactions. It is recommended that dogs be vaccinated for both canine influenza H3N2 and leptospirosis (another disease spreading in LA County).

See attached guidelines to help you help your dog avoid becoming infected with either of these diseases.

Please noteSome pet parents assume that when their pets get their yearly vaccinations that Canine Influenza and Leptospirosis shots are included . They are not. Please discuss these issues with your vet.

What is Canine Influenza & How Can My Dog Get It?

Canine influenza (also known as dog flu) is a contagious respiratory disease in dogs caused by specific Type A influenza viruses known to infect dogs.

Dog Flu can pass from dog to dog through direct physical contact or from virus particles in the air. It can also be spread through objects that were touched by infected dogs, like toys or water bowls.

What is Leptospirosis & How Does My Dog Get It?

Leptospirosis is a bacterial infection that spreads through the bloodstream. Dogs can get leptospirosis from puddles or bodies of water that carry urine from infected wildlife. The bacteria infiltrate a dog’s body by burrowing into their skin.

Canine leptospirosis can be a serious, life-threatening disease.
