Query: Don't waste your money...

I bought this for my collie along with 5 other toys. He loves just about everything, but won't touch this. As another reviewer mentioned, it has a very strong plastic smell that is overpowering. Even with the treats in it it smells like plastic. Then, after a few days the treats began to turn rancid and really stink. There is no way to get the treats out or clean it. I tried everything short of drilling a hole in it. I do not see how anyone could give this anything more than a three. This was a waste of money.
