Prevent the Spread of Dog Flu

A simple vaccination can keep your dog and community safe from an outbreak.

A Highly Contagious Respiratory Disease

All it takes is one interaction for your pet to contract Dog Flu.

It Happens So Fast

Almost every dog exposed to the virus will become infected.2

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.

Danger Zones

Some of your dog’s favorite places are high risk areas. Dog parks, day cares, boarding facilities and other pet-friendly locations can all pose a threat to your dog.
