Food puzzle safety

Food puzzles can bring out aggressive, possessive behavior in even the friendliest of dogs. It's a normal aspect of their behavior as the descendents of scavengers.

Follow these guidelines to keep your family safe:

- Use physical barriers like doors and baby gates to keep kids and other pets away while your dog is solving their food puzzle.

- Some dogs want complete privacy while solving a food puzzles, others will want you to in the room for companionship. Even so, avoid approaching them head on, getting between them and the puzzle, or touching it.

- Always pick up the puzzle and any uneaten food and treats when your dog finishes and before you let others back into the space.

- Never take a puzzle from your dog. Wait for them to walk away or offer them a trade by tossing a better treat a 4-6 feet away and seeing if they voluntarily give up the puzzle to go get it.

- If your dog gives you a stink eye, freezes, growls, or bares, their teeth while they have their puzzle, back up and give them space.

- Reach out to Dogby or a certified dog trainer in your area for help if you are concerned about your dog's behavior around food puzzles.
