Believe it or not they can! I just saw on TV (Petmiracles) a dog running on only their back feet like a human. The dog was as happy as could be. I have seen many dogswith one or two legs missing and still being a loving and loyal pet while having fun. Also there are some dogs that have a little titanium cart with wheels on the back and they are harnessed in. My vet has a cat called 'Chance' that has this type of cart. A bunch of us got together and raised the money and the only place we could have one made was the U.S. Now Chance races around (little orange flag on top) so you can see him coming. We love him!
With extensive care and training, you could train a one legged dog to run. I dont know how long it would take, but probably you could.
Maybe, it could probably stand on its to legs only if it built up its muscle. There was a dog who could stand on its two hind legs, so maybe a panda could too.

Brontosaurus is an invalid name for Apatosaurus excelsus. Apatosaurus was a sauropod, and like all sauropods, it walked on four legs. However, very young Apatosaurus could run on two legs like a basilisk lizard to escape danger.

Theropods only walked on two legs. Some types of small ornithopods were also completely bipedal.
