I like the ideas this kid has in the video below. I tried most of them immediately except for the hole in the yard and the milk jugs tied together. Every dog is different, what is a treasure to some, others could care less. None of my dogs cared for the water bottle in the sock, however my foster dog loved it and later chewed up the sock. She is 8 months old. I have kongs I put peanut butter in, so I tried the paper toilet roll, doesn’t work as well as the Kong. You can also put peanut butter in a small bowl and will work the same. For the treat dispenser I used a heavy plastic jar with lid instead of the plastic bowl w/lid. Kibbles will usually work in these instead of spending money on treats. Watch The Muffin Tin Game (Rainy Day Fun) and Fun Nose Work Ideas at the end of the video.
