During the clip, the two canines, a black-furred one named Gus and the other an unnamed white pup, are seen playing with a green and black toy. As their pet parent Lia, from the USA, narrates that her four-legged friends do this every time when they want the same play thing, both appear determined not to let go.

       Touching nose-to-nose while hardly moving and staring at each other both pit bulls gradually become tired but they both refuse to give in.

       Towards the end of the adorable moment caught on camera, Gus is seen lying down still gripping on, while his white furry sibling still stands as a piano gently plays in the background.
