Yes, but how could Roxy ingest another animal when she is on a chain? The only feces around are probably her own, unless she has Coprophagia (eating feces) and keeps resetting the tapeworm cycle (providing there were eggs in that particular elimination). The only "real" possible way for her to get tapeworm is from fleas - that is where they come from.
