I remember this video when I was playing with our dog named Pierre. I went inside the box and I was panting to get his attention. He would scratch the box, jump and bark. It was really fun!
I was taking photos also while playing with him.In this photo he's like I wonder what's making those strange noises.
He's like I finally found you........ The person making these strange noises.
He even tried going inside the box but he couldn't.
He would just put his head in the side of the box and would try to bite.
Here's a photo of my brother inside the box.
