Looking at the bones inside the human and dog hind legs, you can see that they have analogous structures due to convergent evolution https://kylehallnationaltrust.weebly.com/uploads/2/4/3/7/24374307/1769538_orig.jpg as for some differences: dog legs are bent at a much larger angle, while human legs are mostly straight/vertical. additionally, if you look at the way the leg bends, it looks like dog legs are bent "backwards" compared to human legs (it's not exactly the same, since in the dog it bends at the "ankle" bone). these differences exist mainly because humans walk upright and dogs have to walk on all fours.
