My dog has separation anxiety. Treats help, but he usually finishes them before I even get out the door. In an effort to lower his caloric intake and help with the anxiety, I purchased a Rumbl chew toy from West Paw. This oblong, hollow ball has a “fish-trap” opening on top, so I can load it up with dry treats and prolong the time it takes my dog to get them out, giving me time to make my escape. Even when he gets all of them out, he continues to chew on the toy. It’s a win-win for both of us. $21 in most pet stores, like Dee-O-Gee.
