The dog says, "I hear somebody."
This dog is somebody's pet. It looks to me like this could be an Amish situation. This is how they make a phone call. They do not have phones in their homes.
Ordinarily, there would be a person making a phone call. But today there is no person making a phone call and the doggy doesn't recognize the voice. It's not his owner's voice, it's a stranger.
It looks to me like the dog could have taken the phone off the hook after the phone rang. This is all brand new to the puppy because ordinarily his owner would be there.
The dog says, "Well, I've got to see what's going on here! Where is the person?"
