In video footage she recorded, she approaches Cricket and makes a noise to call him over, only prompting the small horse to run off with the dog balanced on his back.
"I can't make this stuff up!" Ms Schenker, who can be heard laughing in the video, wrote on Facebook.
"So we pull back in our driveway tonight and this is what we see. This is not our dog! But apparently him and Cricket the one eyed wonder pony are best friends.
"I'm stealing the dog, new circus act!"
The dog, who belongs to her neighbours, apparently roams the local area.
Ms Schenker added: "The dog didn't get hurt! No the dog is not abused at his home, he just likes to travel the rural area we live.
"Cricket is fine, he lost his eye along time ago in an incident that had nothing to do with the dog! I did not put the dog on the pony! Honestly I was pulling in my drive way from going to Mcdonalds when I seen this happening."
The video proved highly popular on Facebook, where it had been viewed more than 5.7 million times at the time of writing.
Ms Schenker set up a Facebook page for Cricket and his friends.
