Hello,I came here to get answers for some questions.
I talked to a General Medicine doctor today for my rabies anxiety.So my incidents are following

1.4years ago a german shepherd pet dog of my friend's scratched me in my hand that dog died 1.5year after he bit me,i was scared but clamed down a bit cuz a dog can't live that much.

2 .8months ago some stray dog pups tried to climb onto my leg their claws poked me but didn't recieved any scratch.

So the doctor told me that rabies symptoms appears in 3-8weeks and since its 8months no need to worry and told me to forget about statements that told it comes year later.It hasn't proven and not reliable.He prescribed me with Pre Exposure Prophylaxis for my peace of mind and future protection.Today i got Day 0 shot of vaxirab N 1500iu.

My questions are:
1.If there was no history of Rabies or rabid dog in our locality is there any chance of those pups getting infected?Some pups died but some still alive.
2.What are my chances of getting rabies?
3.Is it really that rabies symptoms occur in 3-8weeks?
4.Are german sheperds furious by nature?

Please answer.
