The video uploader explains that Duncan Lou Who is a Boxer puppy and was born with severely deformed rear legs and pelvis.
His rear legs had to be removed when he was just 12 weeks old.
Now at 16 weeks, Duncan Lou Who is a double-amputee learning to run and it doesn’t seem to be slowing him down!
The uploader says Duncan Lou Who has a custom wheelchair and also does physical therapy every day to correct the damage to his spine since birth, and is regularly going to be doing hydrotherapy for life to help support his muscles.
