Dog acceptation of the collar can take some time and training.

First phone call with Yukiko: EPIC FAIL 
The sound was really to loud and Daniel felt onto his son’s answering-machine.

2nd phone call to Daniel’s wife. Talking about meeting each other later and traying to talk to the dog.
Daniel’s wife: “Yukiko doesn’t reply to me!”

3rd phone call with Yukiko, watch it until the end!
The starting of the conversation is a bit tensed, they talk about the device and the experiment, after having given a biscuit to Yukiko the conversation really starts (about work), as the dog move the owner follows her, down on his knees on the carpet.
Daniel: “It’s the first time I use a hairy phone!”
Daniel: “That is a really ‘mobile’ phone…”
