Nikki is at the chewing stage right now too. She loves the baby Kong, and Dr. Noys dog toys (tiny size) she loves to bite the middle and it squeaks, and a chicken flavored Nylabone (tiny size).......she has tons of other toys, but those are the one's she has for chewing. As with any toy........make sure you supervise them and thow the toy away if it gets worn so they don't swallow anything.
