I was playing with a pet Labrador dog 2 days before. The dog usually gets very excited and he smashed on my hand. I suspect that I got bit by him as today I noticed there are small wound marks on my hand. I am not sure if I got accidentally bit by him. I would like to know if I should take the vaccine and if yes then as 2 days are already passed is it going to be effective. Please also share the cost of the treatment along with the vaccine cost.
