i've heard of it w/food, so i'm sure it works w/ other things. i've heard of nylabone getting stuck in the bowles and killing dogs. but never any hard stories of stuff like this.
well, once there was a great dane or something, i forget what it was, but i seen it on the news. it started getting sick and stuff, so the people took it to the vet, after some testing the people decided to do some x-rays. they found tons of stuff was lodgen in its stomace, so they did an emergancy on the dog. they got alot of items out of the stomage. like forty some different things. ranging from needles to pennies, to whole stuffed animals. it was nutz! (not the dog...all the stuff it ate.) and it had stuff in there that had been missing for over a year. that case totally amazed the vet. thay said the dog should have died long ago from all that stuff!

sorry i can't be of more help. Good luck!!!
