Although the product can be a bit pricey, it can be worth it. I put a Kong liver snap treat (KONG Stuff'N Snacks, Liver, 11-Ounce, Large) in the Kong (KONG Classic Kong Dog Toy, Large, Red) first, then "anchor" it with the liver paste. I stick the whole thing in the freezer for a few hours to a few weeks, until I want to give it to my dog. Freezing makes it last 20-30 minutes instead of the 20-30 seconds it would take her to empty the Kong if it wasn't frozen.She is terrified of thunderstorms, and will keep us up with pacing, barking, howling and whining if not distracted. This stuff will distract her from ANYTHING. Then I can sleep...ZZZzzzzzzzz.........
