I have an empty dog food bag in the garage where the puppies play. It makes lots of noise when they walk on it and that's why I have it there.
As you can see, bag dragging is a new sport and even Aunt Miikka goes to see what's going on.
We play in the garage twice a day and have a grand time.
I have Red on my lap sleeping as I'm typing this, so pups are getting individual attention as well.
