Penny, a fluffy Silkie chicken and Roo, a two-legged Chihuahua have become fast friends after being rescued by Alicia Williams, who works at the Duluth Animal Hospital in the US.
Roo, who was born deformed, was found abandoned in a ditch, while Penny was rescued from being put down when the experiment she had been part of had run its course.
Since being introduced to one another, Roo and Penny have become adorably inseparable, following one another around and doing everything together.
