How should I respond to people who fake suffering? Namo Buddhaya. 
Yesterday a person came to me and said he was bit by a dog and then he asked for money to buy medicines as he had none as he was poor. I gave the money to him.But I wonder whether people fake suffering to win sympathy and/or money ? Should I compromise my pride in honesty to help these fake people ?

Your honesty was not compromised. And don't let your pride grow on you because of these incidents.

Money comes and go. If the money is yours it will eventually come back in any possible way. Be more careful/mindful next time too, of course.
