Yes, and a dog has gnawing and crunching capabilities,
which are similar to our grinding capabilities. The
difference in not just the teeth, but also the
"looseness" of our jaw which allows a slight
sideways-back-and-forth motion.

Hmmm. When I feel my molars, I notice a lot of fairly
sharp ridges along the inside and outside edges. When
I feel my dog's molars (when he let's me :), I feel a
lot of sharp ridges along the edges of his molars.
They are sharper and much more pronounced than mine,
but similar nonetheless. Last time I remember feeling
a horse's molars, I recall they felt nearly smooth to
me. (Sorry, I have no cats, so I can't do the same
test with them).
My dog beats me in the "canine teeth" category, but I
got a pretty good set of "slicing" teeth up front.
Allows me to "cut" into meat whereas my dog has to
"tear" the meat.

Oops, I should have written "grass eater". Oh, wait a
minute, on another post didn't you argue that "To eat
grains is to eat grass - a certain part of it."?
Sorry, that must have been another subject....:)

Again, we are omnivores, and our teeth have developed
to make use of our amazing adaptability. We exhibit
some of the traits, in various degress, of both.

His diet is a "limited version" of our own. A dog
exhibits "some" of the traits of an omnivore, but
still has a greater requirement and preference for meat.
