My dog initially enjoyed it for retrieval. But, he became obsessed with chewing off the material. That was okay for a few days (material is kind of hard to get off) but then he was able to start chewing into pieces and I had to throw away. Lasted all of 3 days.

Consmaterial can be ripped off
heavy chewers can tear it apart and tear off pieces of rubber
