I was delighted to see this buried in the yard. On first look it looks like just some random plastic thing, but you don't understand, or see is that it is actually about 9 inches long! This is a Treatstik, it is a container with a small opening in it where you can put dog food and your dog has to roll it around and earn it's dinner/treat.
Hazel on the other hand, she doesn't actually play with it to earn her food, she grabs it like it's made of gold and scours for a spot in the yard to bury it. I lost it for about 2 weeks once and found it in a bag of potting soil next to the shed. This is the second time she has buried it!
