Eviction in florida with a seven day notice is this legal?

we got a notice to vacate the property within seven days or they will file for an eviction.This is all due to the fact that our neighbors about seven months ago were complaining about our dog and that he barked to much and we had a disagreement. Then we dealt with it and got rid of the dog know they are saying we are noisy on the weekends and have lots of party's which is not true. we haven't got one notice that we are noisy just this letter out of the blue that we have seven days to leave the premises is this legal? and if so how long does this process take and how long do we have to move. I do know that if we don't vacate in seven days they can file for eviction but i need to know how long all of this takes do i have 30 days from today or will it take longer to get a court date ect.... is this even legal with no prior notice regarding the situation.
