My dog doesn't counter surf. I thought it was a clever use for counter surfing though in that TV episode.
The TV show it was aired on does not promote any kind of physical discipline, so I don't think it is an electric collar. Or maybe it was an electric collar where they only used the walkie talkie component?! I searched for awhile and just couldn't figure it out.
Ola--I would think that it could be used for separation anxiety. In fact, I think you could get creative and use it for lots of issues. I was thinking about using it for my dog and barking. She only does it when she is outside, can't see me, and is alerting me about potential "danger." She stops the minute she sees me, so I thought a walkie-talkie kind of collar might work.
