I did buy a very large nylabone for Bo but I threw it away after he chewed into the ends. The package said the dog should chew from the sides, not top or bottom and it didn't say anywhere on the package that it was edible so I threw it away to be on the safe side. I googled and found that Nylabone makes both edible and inedible type bones so I'm going to have to look for the packages that say edible.
I'm going to check out Petmountain.com to see what I can find. Thanks for the heads up on the 14" jolly ball; sounds like something Bo would have a blast with!
