The Nina Ottosson MultiPuzzle level 4 interactive dog puzzle is one of her most challenging puzzles. As with most of Nina’s puzzles, pieces can be removed to adjust the difficulty of the puzzle. On the outside, you have slides similar to the Level 3 Challenge Slider. Then in the middle, the pooch needs to rotate the center and middle orange sliders.

• 28 hidden treat compartments (can fit a cup of food)
• Wash with warm, soapy water once removing all the parts
• BPA, PVC & PHTHALATE FREE

If your pooch is new to puzzles, I suggest starting with a level 1 or level 2
