Gotta love dogs,always doin stuff to get attention. Is a strict leash law here,and most keep their dogs in fenced yards. I have no fence and so Hoover is tethered to 50 foot cable for most of the day.
At night,when it is late,, We go for walks through the neighborhood and sometimes I let him remain free from the cable until I leave for work around 3:00 AM.
Have found all sort's of stuff that he has collected and brought home. Boot's, garden hoses, lawn dart's, Tiki torches,welcome mats, lawn chairs,and my favorite... One very large plastic frog that croaks if you pass close by it.
It amuses him to drag this stuff home, but not so much the neighbors
I generally try to hide the stuff or return it, but I fear a fence or kennel is on my to do list come spring when the ground has thawed a little.
