Yes, that's right. I like to joke about how my dog is basically inside out. You can count her ribs, a few of her backbones, poke all her veins, her flimsy flaps of skin, and who can forget those incredible muscles. A lot of vets love greys for these reasons - makes a greyt anatomy lesson!

Their skin is so thin actually that light shines through

Of course, it'd be considerably easier to see their veins this way.
