I boiught this product for my new dog as it was recommended by the adoption rep.  She has several of them as she has 5 dogs.  I'm eager to use it, but it absolutely reeks of chemicals!  And has been out-gassing on my patio for 2 weeks.  The smell was so strong it was really unbearable. And it can't be healthy to breathe that stuff!  Not for me nor my dog.  I worry about the people in the factory who make it!  It is gradually losing its stench.  That's how I would describe it-- chemical stench.  Other than that, it appears well-made and nice.
