rabies in animals after biting

I have two similar questions:

1. Rabid dogs already have rabies virus in their saliva which they ingest. But why does this affect them only after biting a human? For example, after being bitten, doctors would tell you to observe if the dog will die, and some dogs do. Sometimes, they would recommend that the dog brain be analyzed in a laboratory.

2. I remember my elementary science teacher told us that once a snake has bitten a human, it will try to leave. One way of getting rid of the venom is by letting the snake bite the same spot again so it will ingest the poison. How true is this?

Thanks in advance.

Yeah you makes me wonder about that matter...In snakes situation i know that wasn't true...that is ridiculous...but in the dog situation...that makes me think...why??? I wonder too but the same thing I hears to other people when dog bite someone...the dog should be observe after it bite someone...so it means that the rabis activated when it bite someone...ugh how come???

The rabies isn't activated after a bite. The reason to wait 10 days if the dog is not being put down is because that is how long it takes to see the signs of fulminant rabies. The quarantine period is a measure to make sure that the dog wasn't rabid when it bit someone. If the dog had been rabid, signs should show up in that 10 day period. If the dog is euthanized right away, the head is sent for IFA testing.

Technically, if one believes an animal is rabid they should get post-exposure vaccines before the 10 day period as you need to stop the virus before it enters neurons in the spinal cord, and really there is no evidence that states how long it is safe to wait.

On a scale of 1 to 10, with 1 being a being the lowest degree of truth, 10 being absolute metaphysical certitude ... about -12.

Not all snakes will let go as soon as the bite you- some hang on. Also, not all snakes are venomus....Please do not let a venomus snake bite you again! One the venom is in you, its in you, and you should probably seek medical attention- especially if you don't know what type of snake just bit you.
