What is one of the key vaccines for a dog over three months?

The rabies vaccine is essential for dogs over three months of age due to the high risk of rabies exposure and the serious nature of the disease. Rabies is a viral infection that affects the nervous system and is almost always fatal once symptoms appear. Vaccinating against rabies is not only vital for the health and safety of the dog but is also a legal requirement in many states, including Florida, to help protect public health.

Other vaccines mentioned, such as leptospirosis, Lyme disease, and canine influenza, are important for specific regions or exposures but are not mandated by law for all dogs. The rabies vaccine is universal and is fundamental in preventing a disease that is transmissible to humans. In summary, the rabies vaccine carries significant importance due to its role in disease prevention, legal requirements, and community health implications.
