Large Snuffle Mat - Keeps Dogs BUSY! Stuff each little felt with pieces of their kibble, a few treats, and some Cheerios! 20 min of "sniffing" equals 30 min of walking! Bonus: paw print has a squeaker! Approved by Sophie Doodle and her Mom Kathy! Best to be Supervised! Comes with a handle that you put under a leg of a table or chair to keep it in place! Also use freeze dried treats (sprinkle them all over the mat).
