Has anyone ever heard of a Tongan Terrier?

I recently watched a movie, “The Dog Problem”, in which the featured dog’s breed was referred to as “Tongan Terrier”.

I searched on the internet, but to no avail really. My girlfriend and I would love to get a breed like this, any info would be awesome. Below is a image of the dog if that helps.
