Kimberley Pearce, 40, from North Carolina, was videoing Bella scampering around the house when she believes her beloved cocker spaniel Sadie, who had to be put down just one week earlier, returned to comfort her.
Mrs Pearce said: "It was only a few days after when I was showing the video to a friend that I saw her appear. I just knew it was her. That was my dog.
"You can see it's a white and caramel colour, and so was my little girl.
"The video had been taken around lunchtime and no cars go past my house to make a reflection, and no birds for a shadow or anything. We live quite far out in the country.
She said: "It might sound strange, but a couple of days after Sadie died I finally went and sat out on the porch and had a half hour conversation with her.
"In that conversation I just begged and begged for her or God to send me a sign so that I knew she was okay.
