Dogs are expensive and extremely messy. House sitters are unreliable and even when they are loyal they leave the property at times. If someone wants in, they will be watching and they will break in when the time is right.
Put steel doors and wrought iron gates on all entry points, these are great for vacant and occupied security. Board up all windows with 3/4" plywood, 2x4s and thru bolts. Winterize the property. Remove the furnace and water heater.
I use an alarm company that installs units and moves them from address to address when vacancies occur. If you get a break in you will be notified and the police will be called. Usually they will not have time to steal all of the copper, cabinets, toilets and they will bug out.
