A woman pet-sitting for her grandmother had to dress up just like her - to get the dog to follow commands.

Rebecca Sullivan, 24, and her sister Abby, 19, were dog-sitting for their grandparents but Tyson the dog wouldn't respond to commands.

They came up with a creative way of solving the problem - dressing Rebecca as their grandmother.

Technician Rebecca sported a full outfit straight from the wardrobe of Deborah Grant, 73 - right down to a wig and hat.

After putting on a voice and imitating Deborah's stride, Tyson was fooled - and followed their commands.

Rebecca and Abby, from Magee, Mississippi, US, even later filmed Deborah doing the same thing to show the similarities.

Rebecca said: "My grandparents had taken a trip to Boston for the weekend so we were dog-sitting."

"We thought maybe Tyson was missing my grandmother so we had the idea for me to dress up like her."

"I still had my scrubs on from work so I slipped on a pair of her pants and a top and one of her wigs and a hat."

"As soon as I put them on and called his name, he started following me!"

"I was hopeful it would work but I didn't know - we were just so desperate we were willing to do whatever it took."

"Clearly Tyson believed I looked like her because I hunched over walking like her and talked like her too."

The sweet moment occurred in May 2022, and sadly the family lost Tyson the following year.

But they shared the heart-warming video in a tribute to the much-loved pooch, who was a therapy dog for their grandad, Allen Grant, 75.

Rebecca said: "I remember Tyson being so happy jumping around all afternoon because my grandmother came home."

"Tyson was such a lovely dog, he helped our grandfather out of his depression when he had cancer."

"He got his name because Mike Tyson the boxer bit his opponents ear - and the dog nibbled my grandad's ear too."
