A pet dog has biten my leg over jeans but there a scratch mark on leg and there is no damage in jeans .i thinks that's scratch mark only because of pulling my leg away .its teeth could not touch my leg..a point blooding due to hair breaking ..I have washed my leg with soap after 2 hour.owner of dog said they give the dog vaccines routinely..now 8 days are passed ..what should I do now..is there any worry ???
