Kyjen Hide-A-Squirrel Puzzle Toy for Dogs
Prevent your dog from becoming bored with the Kyjen Hide-A-Squirrel. It helps develop your petﾒs intelligence and puzzle-solving skills too. Just hide the 3 included soft plush squeaker squirrels inside the plush tree trunk. Your pet will have a blast poking around the trunk figuring out how to remove the squirrels. After your dog removes the squirrels, just place them back inside the trunk for more deductive fun. No assembly required. Great for dogs of all ages and breeds. The plush material is durable enough to withstand many hours of rough play.
