Roo is a five-month-old puppy who was born with three legs and tragically lost another shortly after birth.
The hopping pup was adopted by 50-year-old nurse Nikki Dick and her firefighter husband Ian from Morpeth, Northumberland.
"Roo doesn't know any different to hopping on her two back legs but she still laps up all the fuss from people who always stop and do a double take when they see her because they think she is a kangaroo," she said.
"She's perfectly happy and pain free and vets are very happy with her progress.
"We've fallen in love with her, how could you not? She’s such a little star."
The couple take Roo to hydrotherapy and physiotherapy sessions every week to help her deal with the strain of her unusual walking method.
"People always want to know more about Roo which is great because it spreads the word about Safe Rescue," Dick added.
"If they hadn't brought Roo to the UK she would not have survived living on the streets with two legs. She wouldn’t be here now.
"Despite what she has been through she is full of personality and so loving and we feel very lucky to have her. She might look like a kangaroo but to us she is just our little puppy Roo."
Kelly Hare, co-founder and director of Safe Rescue For Dogs, told The Telegraph: "She has never known life with four legs so it’s not like she looks at other dogs and wishes she had four legs.
"She’s just making the best of what she has and doing a fine job of it."
