After a dog is bitten by an encephalitis tick, symptoms can include fever, lethargy, and neurological signs such as seizures or paralysis. These symptoms typically appear within 5-7 days following the bite.

Tick-borne encephalitis (TBE) is a viral infection transmitted through the bite of infected ticks, primarily Ixodes ricinus and Ixodes persulcatus. In dogs, symptoms following a tick bite from an encephalitis tick can vary, but they typically manifest in two phases: early symptoms and late-stage neurological signs.

Early symptoms usually appear within 7 to 14 days after the tick bite and are often mild and nonspecific. These may include fever, lethargy, loss of appetite, and general discomfort. The dog might show a reluctance to move or exhibit a change in behavior, such as increased irritability or sensitivity to touch, particularly around the area of the tick bite. Some dogs may also develop swelling or inflammation at the site of the bite.

As the infection progresses, late-stage neurological signs become more apparent. These symptoms can manifest within a few weeks to several months after the initial tick bite and are often preceded by a period of remission. The most common neurological signs include:

  1. Ataxia: This refers to an uncoordinated or wobbly gait, which can affect both the hind and forelimbs. Dogs may stumble, have difficulty standing, or appear weak in their legs.

  2. Paralysis: In severe cases, dogs may develop partial or complete paralysis, particularly affecting the limbs but potentially involving other parts of the body as well.

  3. Seizures: TBE can cause seizure activity, ranging from mild twitches to full-blown convulsions. These seizures can be generalized or focal, meaning they may affect only one part of the body.

  4. Behavioral Changes: Dogs might exhibit unusual behavior, such as aggression, disorientation, or a decreased response to commands and environmental stimuli. They may also show signs of depression or anxiety.

  5. Sensitivity to Light: Photophobia is another symptom that can occur in dogs infected with TBE. This sensitivity to light may cause the dog to squint or avoid brightly lit areas.

  6. Neck Stiffness: Dogs might exhibit a stiff neck, making it difficult for them to turn their head or move it normally.

If you suspect that your dog has been bitten by an encephalitis tick and is exhibiting any of these symptoms, it is crucial to consult with a veterinarian promptly. Early diagnosis and treatment can significantly improve the prognosis and prevent the development of severe neurological complications. Vaccination against TBE is also available in some regions and can provide protection for dogs at risk of exposure.
