This puzzle takes unlocking to a new level! Your little one will need to master 3 things (and in the right order).

1. Moving the bone-shaped locks into place to unlock the drawers
2. Make the connection that the position means the drawers can now open
3. Open the drawers using their paws or their mouth

You might need to help them a bit, and when taking on a very difficult puzzle like this one, it won't be a bad idea to hide more than a few treat pieces, in order to encourage your dog with easier, multiple finds as they do their best to get the hang of it.
