This puppy named Pippen walks like a T-Rex and jumps like a bunny after he was born with no front legs.
But the dog's owners from Orlando, Florida, say he has a happy life and is not in pain.
They wrote on Facebook: "He is in no pain, nor is he 'miserable' or a 'poor baby' just because he has no front legs. He has a birth defect where he was born with no front legs.
Aside from that he is a completely normal, happy, healthy puppy.
"He plays and bites with his razor sharp raptor teeth and whines to be held and eat. We can learn so much from dogs. They adapt and they move on, and they do so with a tongue-lolling smile!
The owners plan to get him a set of wheels, but only when he is fully grown, the Daily Mail reports.
They wrote: "He will get a set of wheels. But he is only 8 weeks old. He needs to grow before we can fit him for a set of wheels.
"He is growing rapidly. He is visually larger today than he was even four days ago. Any wheels purchased or built today would not fit him correctly a week from now.
"Our carts come from Eddie's Wheels for Pets where they custom build for us to exact measurements and specifications of each individual dog. We are not just going to throw something together and slap it on him for fear of hurting his back due to the unique way in which he moves.
"So for now, he is walking like a T-rex and hopping like a bunny on his hind legs. Sometimes he scoots and slides around. He is not hurting himself. He is fine.
Responding to comments from viewers online, the owners wrote: "To those of you who have commented and view him as a beautiful, inspirational, deserving and worthy dog... THANK YOU! You are exactly right. To those who have laughed at the 'freak' and expressed that he is not deserving of a happy life... shame on you. You have a lot to learn."
