How can I keep my dog entertained in their crate while I am at work?

To keep your dog entertained in their crate while you are at work, you can provide them with interactive toys, puzzle feeders, and safe chew toys. You can also leave them with a comfortable blanket or clothing item that smells like you for comfort. Additionally, consider leaving a radio or TV on for background noise. Remember to rotate their toys regularly to keep them engaged and prevent boredom.
