Friend of a friend and her husband adopted 2 dogs when they moved into a rent house 3yrs ago. Husband's job moved to Dallas, they got an apartment (40min from rent house). Gave dogs to her sister about 30 minutes from rent house. Dogs stayed with the sister about 2 weeks and disappeared. Showed up at the rent house 2 weeks later. Sister came and got them, neighbor recognized them, took them back to her home. REPEAT, a week later. Next door neighbor to rent house now owns happy dogs that live next to their " home"! Many years ago I worked for a lady who took in her brother's dog after the brother passed away. They lived 3and Half hours apart. Lady had the dog a few days and it disappeared only to show up at the brother's old house (now with new owners) 4months later. Neighbor recognized the dog even though it was skinny and terribly matted. New house owners kept that dog. I just heard the first story today, reminded me of the second.
