If my dog bites me in face?

Matter of fact, I wish the answer was yes. I want you to be able to sue your dog for ALL of its money. Then, you will get a huge lump sum of ZERO pesos or dollars :D
Problemo solved!

I think you should stick to playing fetch with your balls.

I hope you realized by suing your dog for biting you that you in fact would be suing you self for all your money as you own the dog. If you are unable to realize this then I suggest you go back to school and demand a better education.

"Sue this!"
