How does rabies manifest in dogs, what are the symptoms? - briefly
Rabies in dogs is typically characterized by behavioral changes such as aggression and restlessness, followed by paralysis of the throat and jaw muscles, leading to difficulty swallowing and excessive drooling. These symptoms progress rapidly, often resulting in death within days if left untreated.
How does rabies manifest in dogs, what are the symptoms? - in detail
Rabies is a viral disease that affects the nervous system of mammals, including dogs. In dogs, the virus attacks the brain and spinal cord, leading to behavioral changes and eventual death. The incubation period for rabies in dogs can vary greatly, from days to months or even years, depending on the severity of the bite and the location of the infected tissue. However, once symptoms appear, the disease progresses rapidly.
The early symptoms of rabies in dogs are often subtle and non-specific. These may include:
-
Behavioral Changes: Dogs may become more aggressive or anxious than usual. They might also show signs of disorientation or confusion. Some dogs may appear more affectionate or friendly than normal, which can be misleading as this is known as the "dumb rabies" stage.
-
Appetite Loss: A loss of appetite is one of the early indicators that something is wrong. Dogs may refuse food and water, leading to dehydration if not addressed promptly.
-
Excessive Drooling or Salivating: As the virus affects the throat and mouth, dogs may start to drool excessively. This is often referred to as "foaming at the mouth," although it's more accurate to describe it as excessive salivation.
As the disease progresses, the symptoms become more severe and distinctive:
-
Paralysis: Rabies can cause partial or complete paralysis. Initially, dogs may show weakness or lameness in one limb, which then spreads to other parts of the body.
-
Seizures: Dogs with rabies often experience seizures or convulsions. These can be mild or severe and may involve the entire body.
-
Changes in Barking Patterns: The dog's bark may change, becoming either hoarse or unusually high-pitched. Some dogs may also develop a fear of water due to difficulty swallowing.
-
Hydrophobia: One of the most well-known symptoms of rabies is hydrophobia—an intense fear of water. This symptom arises from the difficulty in swallowing, which can cause choking and breathing difficulties when the dog attempts to drink.
-
Photosensitivity: Some dogs with rabies may become overly sensitive to light, displaying aversion or discomfort in bright environments.
The final stage of rabies is coma and death. Once clinical signs appear, rabies is almost always fatal. There is no known cure for rabies once symptoms have started. Therefore, preventive measures such as vaccination are crucial in protecting dogs from this deadly disease. If you suspect your dog has been exposed to rabies, it is essential to contact a veterinarian immediately for guidance and appropriate care.
