A walk tires the legs, not the brain. Dogs that never get to use their nose turn restless and bored, and that is when the chewing, whining and pacing around the house starts.

These are snuffle mats you can pick up and play with. Soft polar fleece with crinkle paper sewn inside, so it crackles with every nudge. Tuck treats between the fleece petals and your dog has to sniff, shake and carry to work them out, light enough to take from room to room or along in the car.
