Final answer:
The Bordetella vaccine is administered to dogs to prevent kennel cough and other respiratory diseases caused by Bordetella bronchiseptica.
Step-by-step explanation:
The Bordetella vaccine is given to dogs to prevent canine respiratory diseases, such as kennel cough. This vaccine targets the bacteria Bordetella bronchiseptica, which can cause severe coughing and other respiratory symptoms in dogs. Vaccines like the Bordetella vaccine help to stimulate the dog's immune system to produce antibodies that can fight off the disease if the dog is ever exposed to it. It is part of the standard vaccination protocol for dogs due to how easily the respiratory disease can spread, especially in areas where dogs are in close quarters, such as kennels or shelters.
