When my Chewy was little, she would try to get sticks, too. She especially loved the driftwood she would find at the beach! But, I pretty much always have kept her with a harness and a 16 foot leash, so I can "reel" her in when she found one. I know they can get splinters stuck in their esophgus, or stomach, or mouths. So, be careful folks. Don't let them have them! They will grow out of it...it probably has to do with teething.
