Hi Doctor, I am 43 kg and 5'1" in height. I was playing with my dog yesterday, he's around between 3 to 4 mos, not sure, he bite my shorts but it slipped and the tooth scratch to my leg. I thought it it was nothing but after a minute I take a look and it's a 2 cm scratch it didn't bleed much but there's a red line of the blood like when you are scratch by a stick or something. Do I need to take vaccines for this? Please advise.
