That's so cute! She got right onto it. I found a tunnel at a garage sale...a kid's tunnel. It works just fine for these two little squirts to play with. It's a little bigger around than yours. I put it away for a while so I can bring it back out to make it freshly fun. haha. When my Doberman and I use to do agility, the tunnel was his absolute favorite. He'd go back and forth through it...just got a real charge out of it. And the chute too. I think that's great that you're playing with your dog...it's the cutest!
