If your dog has canine influenza he will need to see a Vet immediately for treatment.

Never try to treat your animal with human medicine as a vast number of human treatments are toxic and could be fatal to your dog.

How harmful 1-10 is the flu?

I'd say a 1 for many otherwise healthy people, and 11 for those who die. Approximately 36,000 people die from influenza each year in the US alone. They are mostly the elderly over 65 and infants under 6 months, since infectious diseases in both of those demographic groups can be much more deadly than for other groups.

According to the Centers for Disease Control and Prevention (CDC):

"Seasonal influenza can cause mild to severe illness, and at times can lead to death. Each year, in the United States, on average 36,000 people die from flu-related complications and more than 200,000 people are hospitalized from flu-related causes. Of those hospitalized, 20,000 are children younger than 5 years old. Over 90% of deaths and about 60 percent of hospitalization occur in people older than 65.

How long does it take for rabies to kill a human?

It depends on the bite. A leg or arm may take a week or so but the face or neck may take a few days. It can be treated with 12 painful shots, however, once the symptoms start, there is very little chance of survival unless you have a strong immune system or immune to the virus altogether.

Additional info:

Rabies can be in the body for many months before showing signs and symptoms. When it does, there is very little chance of survival. As above, the place a bite occurs, can determine how fast it travels to the central nervous system.
