Tom and Jenny
This is a problem more and more owners are showing increased frustration with and is a problem for both your community and the Entidad.
Your community rules should state that in the gardens and pool areas animals should be on a lead but I think it is unfair to allow dogs on there however cats also create a nuisance with mess.
I recently contactedJthe Entidad to ask what their stance was in light of the fact that San javier Town Hall recently launched a campaign highlighting fines payable for allowing your dog to mess in public areas. So far little seems to have been discussed and I would urge you and all others who have come across this problem to contact both Housing as Administrators at info@housingcomunidades.com as well as your community President asking them to forward your queries to the Entidad.
The more of us who show concern, perhaps the quicker something will be done.
