Get Your Dog Care Questions Answered by Experts
The best option is to take her to a veterinarian for evaluation (fractures, neurologic status) and proactive treatment for central nervous system (CNS)/brain inflammation. The signs you describe (paralysis, lack of coordination) indicate CNS trauma that may progress over time.
If seeing a vet is not an option, watch for signs of CNS trauma such as increased incoordination, lethargy, depression, lack of responsiveness.
Avoid giving nonsteroidal drugs such as aspirin that affect platelet function and clotting. They increase the risk of bleeding, which can increase intracranial pressure if it occurs in the cranium.
Let me know if you have follow up questions.
They are good. Corticosteroids (prednisone) is often used and is an excellent antiinflammatory drug particularly for CNS swelling. It works best if given before swelling gets severe enough to produce obvious signs. Diuretics are sometimes used to reduce fluid accumulation also.
It will not help if bleeding into the cranium is occurring, which is a reason to not use aspirin or other non steroidal antiinflammatory drugs.
Keeping the dog quiet is useful. If you can localize trauma (pain over the jaw, etc.) cold packing those areas also helps.
