Silvia also chewed on the pellets when we first started training her. It worried me that she would ingest them and them swell in her tiny belly, but we never had that issue. It was like she just wanted to chew them and shred them. She never threw up or anything like that. She did eventually stop doing this, not really sure what the change was, but we began to notice less and less shredded pellets, until there aren't anymore now. I think it's just the novelty of something new to chew on, like the above poster said. Of course, some things just won't work for some dogs, but I belive it's worth the try just like any other kind of training option, considering the ease of it after trained.
