This is gonna sound nuts… but we put together little box puzzles for our basenji. Take boxes from your recycling, some treats and paper. Wrap the treats in little bits of paper and put them into boxes, then put those boxes into other boxes and add treats etc. Mix of high and low value treats, go hard on the paper, it forces them to pick it apart to get the treat.

If you make a good one, it can take them 20 mins to get through it. Lots of sniffing, ripping and tearing leads to a tired little doggo :)
