zippered bags for hunger, activities, owies, etc.
Fill a bucket with water and some of your pets favorite toys. (You could also add treats…carrots, green beans, etc.) Freeze the bucket. (You can use a myriad of things to freeze the water…milk jugs, milk cartons, plastic bottles) When completely frozen, remove the huge block of ice from the bucket and place outside. Your dogs will have an exciting time licking the ice to get to their toys.
Summer fun for your pet;)
