Paralyasis caused by neurotoxins released by female ticks in dogs which is mostly ascending in nature is called tick paralysis. Paralysis may occur after 3-4 days of initial tick infestation. A single tick may also cause tick paralysis. Neurotoxins released by ticks causes interference in the release of acetylecholine at neuromuscular junction which causes interruption of calcium flux across axonal membrane as suggested by best pet clinic in Gurugram (Pet Prime veterinary clinic in Gurugram).

What are the systems affected in tick paralysis:

  1. Nervous system: Peripheral nervous system and neuromuscular junction most affected systems. Cranial and Vagus nerves can become involved.
  2. Respiratory system: There may be paralysis of the intercostal muscles and diaphragm in advanced cases of tick paralysis. Caudal brainstem and respiratory center may be affected in few cases.


General signs and symptoms of tick paralysis: History of tick infestation in the affected dogs approximately 1 week before onset of signs. weakness in the pelvic limbs which progresses to the thoracic limbs within 12–72 hours. Stiffness of the legs and joints may also occur. Patient becomes extremely weak to recumbent in 1–3 days in advanced cases but the Pain sensation preserved with no hyperesthesia. Cranial nerve dysfunction also happens in severely advanced cases. When facial weakness happens there is pain in swallowing and eating (dysphagia). Pulmonary edema may occour due to respiratory involvement. progressive reduction in respiratory rate mat occur. Patients may show hypoventilation and respiratory acidosis due to accumulated carbondioxide in lungs. Urinary bladder dysfunction may be present in some cases.


Diagnostic procedures for tick paralysis:

  1. History of tick infestation.
  2. Electrodiagnostics—electromyogram also helps in diagnosing tick paralysis by analyzing myoactivity.


How to treat tick paralysis:  

A. Use acaricidal drugs like ivermectin 0.4 mg/kg bw, doramectin etc.

B. Use nervine tonic to cure nervous symptoms.

c. Remove ticks from dog’s coat manually

D. Use spot on solution for tick removal

E. Use Oxygen cage to prevent hypoventilation and hypoxia.

F. Intravenous fluid therapy should be given if patient unable to eat or drink due to dysphagia, vomiting or regurgitation.

G. Use oxytetracycline through intravenous route to avoid secondary bacterial infection suggested by Pet Prime veterinary clinic in Gurugram.

H. Use supportive medication as well to cure other secondary signs and symptoms like inappetence, dullness, fever etc.



Although humans can acquire the disease by being bitten by the same ticks but tick paralysis is not transmitted to humans from affected pets.
