I haven't done any with Caleb in about 3 weeks (yeah, bad Mom). After work today, I put 5 hides out upstairs and closed the door at the bottom of the steps to let them age a little. The dog that usually blows through thresholds got as far as putting his feet on the bottom step before he stepped down and found the hide just inside the door frame. It took him maybe 6 minutes to find all 5 hides. Two hides were totally inaccessible- one in the bathroom vanity, the other in my husband's top dresser drawer. The bathroom hide meant he had to get his feet off the bathmat, something he doesn't like to do. The hide that gave him the most trouble was the one I put inside a shoe on the shoe rack. But he worked at without getting frustrated until he found it.
