This makes me think of Duane Hanson's work, the hyperrealist artist.
You should definitely do it, it'd be great to see dogs walking around with lifelike looking limbs in their mouths...it would terrify people, heh.
I think I would see it as hilarious, and would give one to a dog if I had one.
Although, it would be weird to wake up with one laying next to me on my pillow...
