The Wobbler makes our dogs a lot of fun and was accepted directly. As a dog owner you would be about the fun to develop the favorites, however, should take into account that the wobbler is hard plastic and therefore caused quite a lot of noise when it slithers parquet floors. Our dogs playing quite wild with it - to the nerves of the neighbors to spare but only dosed with the wobbler. Conclusion: The dogs are happy - the neighbors do not like that.
