$2000.00 for astro turf!!! Wow!
I've seen that short green carpet which looks like grass and that works really well. I don't think its called astro turf though since it is much shorter. You can find it at camping stores or even Home Depo. Its not really that expensive and it is easy to clean with a hose.
Hollie will hide her treats and her dog food. Her favorite hiding place is under MY pillow in the bed. She has tried to hide her entire food bowl by pushing one of her plush toys with her nose in an attempt to get the toy on top of her food bowl. Why doesn't she just use her mouth to pick it up and place it on the bowl? Silly dog!
