I thought there might already be a thread about homemade dog puzzles, but I couldn't find it. Anyway, I know a lot of you make puzzle toys for your dogs. I would love to know what you make yours out of.
I recently made one for my sheltie, using an empty oatmeal container with a small hole cut in the lid - just big enough for one piece of kibble to fit through. She has to pick it up by the bottom to get the treats to fall out, and it keeps her occupied for twenty minutes or so.
Wrapping treats in a towel also works quite well for us. I'd love to hear what your ideas are.
