I used to play this game with my first berner and I forgot how entertaining it is. Hide the "milkbones" or any piece of food. What I do is hide a bunch of pieces of tasty food (like milkbones) around the livingroom. Then I let the dogs in to "hunt". It's really interesting to see them scent the air and work their way towards the piece of food. Then scent another.
I received this free sample of dental kibble and it must be really tasty because one of the cats ripped open the bag. So, I put a bunch of pieces around the livingroom and had great fun watching them play the game. Lola was the ulitmate winner - finding the hardest pieces that I had placed in a spot that the dogs rarely go.As I write this little blurb, they are still looking around alhtough all the pieces have now been found and eaten.
