You can minimise the chance of your dog contracting infectious tracheobronchitis by having your dog vaccinated. This vaccination is given by a squirt up the nose, not an injection! This gets the immunity right where it is needed.
Although the vaccination does a great job of reducing the risk of infection, it doesn’t completely prevent your dog picking up kennel cough as there are so many different pathogens that can cause it. In most cases however, if your dog does pick up kennel cough despite the vaccination, the signs are much milder than they would have been otherwise, and recovery time is shorter.
It is important to note that your standard yearly booster does not protect against infectious bronchitis/kennel cough, so you’ll need to make sure you get this for your dog as well as their standard annual injection. Both can be done at the same time, so you don’t have to make an extra trip, and each kennel cough vaccination lasts a year.
