I was going to ask if the dogs are left on premises on off hours to deter theft but then saw the file name. I have a friend that worked on new build home developments. 3 guys broke in overnight and tried to steal a generator, cut the power that was a hardline. Guy got fried and died while his two "friends" ran.
Heh, yep...these were two local dogs that escaped their owner's vehicle and swam across the river into our construction site. I had to leash them with a spare tagline from a crane and escort them to the entrance of the site to be reunited with their (very apologetic) owner.
Apparently they saw all of the construction workers and wanted to come say hello.
