How does rabies manifest in dogs? - briefly
Rabies in dogs typically manifests through changes in behavior and physical appearance. Initially, infected dogs may exhibit unusual shyness or aggression, followed by symptoms such as excessive drooling, difficulty swallowing, and paralysis of the throat and jaw muscles, often leading to death within days if left untreated.
How does rabies manifest in dogs? - in detail
Rabies is a highly contagious and fatal viral disease that affects mammals, including dogs. The clinical manifestations of rabies in dogs can be divided into three distinct stages: prodromal, furious, and paralytic (or dumb) phases.
The prodromal phase is the initial stage of infection, lasting from one to three days. During this period, dogs may exhibit subtle behavioral changes such as increased irritability, apprehension, or aggressiveness. The animal might also display a change in vocalization patterns, becoming either excessively vocal or unusually quiet. Additionally, dogs may show signs of partial paralysis, particularly in the hindquarters, leading to an unsteady gait or difficulty walking.
The furious phase is the next stage and is characterized by pronounced changes in behavior. Dogs in this phase often exhibit extreme aggression, attacking any object or animal that comes into their vicinity. This hyperactivity and aggressive behavior can persist for several days before progressing to the final stage of the disease. It's important to note that during the furious phase, dogs may also display hypersensitivity to light, sound, and touch, which can exacerbate their aggressive behavior.
The paralytic or dumb phase is the final stage of rabies infection in dogs. During this phase, the dog's nervous system begins to shut down, leading to progressive paralysis. The paralysis typically starts in the throat and jaw muscles, causing difficulty swallowing and a characteristic "dropped jaw" appearance. As the disease progresses, the paralysis spreads to other parts of the body, ultimately resulting in respiratory failure and death. In some cases, dogs may exhibit excessive salivation or drooling, which is often associated with the inability to swallow properly.
It's crucial to recognize that once clinical signs of rabies appear in a dog, the disease is almost always fatal. Therefore, prevention through vaccination and avoiding contact with potentially infected animals are the most effective measures against this devastating disease. If you suspect a dog may have rabies, it is essential to seek immediate veterinary care and follow local regulations regarding animal bites and potential exposure to rabies.
