This is my absolute busiest time of year. I am a textile and polymer clay artist. I get so many Christmas commissions I'm working 14-16 hours a day for about three weeks straight. I rely on these and other brain games to keep her busy. She especially loves the shred balls, and they're easy to make. This one is amazon packing paper and paper tape. Roll up the paper, adding treats here and there. Add a tape layer then more paper and treats. The more layers it has, the longer they stay busy. Make sure to watch them carefully the first time to make sure your dog doesn't ingest the paper. Enjoy!
