Excuse me, Nylabone, I'm not sure what you think I do with my pets, but this does not look like something I should be sharing with my dog. At 10", this is pretty close to actual sex-toy size, although it's probably hard as a rock...if you're into that sort of thing. It has been a long tradition that it's nearly impossible to tell them apart much of the time, which goes to show what dog-toy designers have on their mind most of the time. My new Kickstarter: hybrid dog/sex toys -- half the manufacturing process, since we reuse the same molds for both, just different packaging, we'll be brazillionaires!
