<s>[INST] my father has been scratched by a dog teeth in the leg .It was an outside dog so whether my father should take injection or not and what might be the cost of the injection if he takes [/INST] Dear User, 1. Since the dog was aggressive we must assume it had rabies. 2. Even a bite by an animal which is not aggressive, like a cat can cause rabies. 3. I recommend "January Diagnostics" company (5 ml injection) costing 1,780 Rs. It is a good company. It has a Dacha Japan collaboration. 4. Immediately take the course of injections. Do it right now. Thanks for asking, Chat Doctor. www.bit.ly/ask Chat Doctor.  </s>
