The Western Connecticut Council of Governments, the regional planning agency for 18 municipalities from Sherman down to Stamford, is studying the potential for improvements or sharing of animal control facilities and services.  A pre-bid meeting was held last week about implementing a plan to accommodate trends in local and regional animal control.  The submission period ended June 15.  WestCOG officials say like many public services, animal control is having to find ways to do more with the same, if not less.  Officials say sharing of services, combined with advanced technology, may result in cost savings and economies of scale.  The proposed project will consider a range of ownership, governance, operations and financial models.  Bidders were asked to create shortlist of realistic improvement scenarios.
