We love the tuna and ham noseworks toys! We especially like that the ham has crinkle in the top and having the Velcro closure is awesome in upping the difficulty. My bichon solves puzzles so quickly so my expectations low but I get a good 15 minutes at least. The “pockets” are harder to get open and get the food from than a snuffle mat so she has to work harder, which she and I both love.
