Weeelllll, technically, that's not right. All mammals have knees that bend in
the same basic direction - as long as you have a consistent definition for a
knee. In most mammals, though, the thigh bone is much shorter and compacted
into the body, with a much elongated shin and, usually, a much elongated
"foot".
This picture shows it pretty well:

If you look at the outline, you can see why it is that we don't really notice
the knee, per se - it is hidden in the structure of the upper leg and body.
Take your dog, for example. What you are calling its "knee" is actually its
ankle (analogizing to human anatomy). It's foot is long and thin, and doesn't
really touch the ground - instead, your dog walks, basically, on his toes only.
Personally, I find the most interesting manifestation of this to be the dog's
dew claws ... which is analogous to our thumb. (or big toe, as the case may
be).
Perhaps this should follow up to OT.fun.dogsfeet?
