Introduction
Rabies is one of the best-known—and most feared—diseases in the world of animal health. Even with widely publicized vaccination campaigns, it still represents a serious risk to dogs, cats, and humans. Understanding how rabies works, what its symptoms are, and, above all, how to prevent it is essential to protecting your pet and the whole family.
Rabies disease: what it is and why it's a concern.
Rabies is a viral infection caused by a virus of the genus Lyssavirus , which affects the central nervous system of mammals. It is a zoonosis, meaning it can be transmitted from animals to humans. Once clinical signs appear, the disease is almost always fatal, making prevention absolutely essential.

How is rabies transmitted?
Rabies is transmitted primarily through the saliva of infected animals, usually via bites. The virus enters the body through broken skin or mucous membranes and slowly migrates to the nervous system. Dogs and cats can contract the disease by coming into contact with wild animals, such as bats, or other unvaccinated animals. A disease that was once more common in rural areas has spread to cities as well with urban expansion.
Main symptoms of rabies in dogs and cats
The signs of rabies vary depending on the stage of infection, but they usually involve marked behavioral changes. The pet may exhibit sudden aggression, restlessness, disorientation, and changes in vocal pattern. As the disease progresses, more serious neurological symptoms appear, such as difficulty swallowing, excessive salivation, paralysis, and seizures.
Clinical evolution and severity of rabies disease
After infection, the virus can remain dormant for weeks or even months before the first signs appear. When rabies manifests clinically, the progression is rapid and severe. Damage to the nervous system leads to the failure of vital functions, and there is no effective treatment after the onset of symptoms, which reinforces the severity of the disease.
Why rabies is still a real risk.
Even with vaccination available, rabies remains a concern due to the circulation of the virus in wild animals and the failure to immunize part of the pet population. Animals without adequate vaccination, access to the outdoors, or contact with high-risk areas are more vulnerable. Furthermore, because it is a fatal zoonotic disease, any suspected case requires immediate attention from health authorities.

Prevention: the only effective way to combat rabies.
Vaccination is the only truly effective way to prevent rabies . Dogs and cats should receive the rabies vaccine according to the recommended schedule, with periodic boosters throughout their lives. Avoiding contact between pets and unknown animals, especially wild animals, and maintaining supervision in outdoor environments are also fundamental measures to reduce risks.
Practical benefits for tutors
By better understanding rabies , pet owners can take preventative action, keep their pet's vaccination schedule up to date, and reduce the risk of exposure. This care protects not only the pet but also the family and the community, as the disease involves public health.
When genetics transforms into intelligent care.
petgenoma uses genetic testing to help pet owners better understand their pet's overall health, including predispositions that can impact immune response and well-being throughout life. Although rabies is preventable through vaccination, knowing a pet's genetic profile contributes to a more comprehensive approach to care, prevention, and longevity.
