The Wooly Snuffle Mat, available at Pet Food Warehouse, is an interesting way to serve up food or treats for your dog. The concept: Your dog's powerful sense of smell is engaged as he snuffles, snorts and sniffs his way through mealtime. Created to stimulate a dog's natural foraging instincts by mimicking the hunt for food in grass. Easy to clean. Just toss in the washer and dryer.
