Okay, now this fellow has digigrade legs, so they are more canine than human. His right leg is turned a little so we can see his cute little paw-pads! His legs are a little difficult to explain... His thighs and lower leg past the heel are about the same length. The middle portion between those two parts is slightly smaller. I studied my own dog's legs a lot over the past few years to get the shape right. Referencing real life is a great way to add detail and a touch of believability to your art ^^
The one leg has been what you call "fore-shortened" meaning that it looks a tiny bit bigger than the other because its facing us. Notice we don't really see the thigh?
