Heartwarming footage of a dog being trained to use his prosthetic limbs after, it's thought, his mother clawed his rear paws off when he was a young puppy. <br /><br />The video, filmed in Livermore, California, USA on April 25, shows three-year-old Panda learning to use his new rear legs. <br /><br />The filmer told Panda's story online, writing: "I rescued him at the age of 16 weeks as he had a tough time finding a family because he was missing his two rear paws. <br /><br />"He needed a family to keep a very close eye on him and to get him prosthetics so he can learn to walk on all four legs. <br /><br />"It's believed his mother chewed his two rear paws off when he was a young pup," he continued. <br /><br />"I opted to help Panda get prosthetics as he was able to use his rear limbs. <br /><br />"I didn't want to confine him to a wheelie as he was able to walk on his two front paws and two rear nubs. <br /><br />"Overtime, without prosthetics, Panda would end up with back issues and other ailments. <br /><br />"All he wanted to do was to just dream of running. <br /><br />"The moment when Panda was able to run on all four legs was the happiest moment in my life."
