Enrichment toys and activities are essential for a dog's mental stimulation and can easily be created at home. For DIY options, consider crafting a snuffle mat using fleece or old towels for scent work, or create puzzle toys by hiding treats in cardboard boxes or under cups in a homemade shell game. Engaging dogs in games like Hide and Seek or setting up obstacle courses with household items also offers great mental and physical exercise. These activities not only prevent boredom but also discourage destructive behavior by keeping dogs mentally sharp and physically active.
