Had this problem with two of a neighbors dogs. They let the dogs out for extended periods in their invisible fence controlled yard and the dogs just barked away constantly. Sent an email advising them of the concern. They responded and advised they had two new dogs and aware of problem and working on it.
When nothing changed I referenced the Marion County nuisance animal ordinance. It states pets can be considered as "nuisance animals" if they bark more than 15 minutes at a time and it can be heard on adjoining lots. It would warrant a visit from animal control. That was the end of the barking.
I see Sumter County has similar wording in their codes. Here's a link. Not sure of Lake but if you live there check that also.

On the link, click on Chapter 4 Animal Control. Then see 4.7 entitled "Public Nuisance Animals".
