I had to run out to get more kennel supplies so I was at an ag store and bout a large bag of dog toys, a bone that looks like half a dinasaur, and a bunch of chewies. I dumped them in the shavings and they immediately started to bury them. Then 2 little 10 pounders were fighting over this bone 4 times their size. I laughed cause I can't cut that one up for them.
