At 6 weeks the puppies discovered the tube. Just like the previous litter, these find that not only is it fun to run through, but a great place to catch a nap. Here Red puppy looks out past another puppy that is lying head first in the tunnel. What you can't see is another puppy snoozing further up the tube.
Here Red puppy is coming out of the tube after running through it and then back.
Once again, Red laying in the tube.
