A dog trained to identify a person with a long black dog train can detect the person with the train as long as they are not in the same room, according to a new study.

Researchers at the University of North Carolina at Chapel Hill found that the dogs are able to detect faces, even with a distance of more than a meter.

The researchers tested the dogs in the U.S. on a wide variety of tasks and found that dogs can detect a person as long distance as 3 meters.

“The dogs were trained to detect a face in a room with the person,” said lead author Robert Lohman, a psychology professor at UNC-Chapel Hill.

“That is a really, really, big improvement.

I mean, if you were a stranger, you would never have guessed that you were there.”

The study, which was published in the journal PLOS ONE, also showed that the trained dogs were able to distinguish between people with a short, long and medium-length black dog.

Lohmann said the dogs were not trained to recognize people with long black dogs, which are used by people with mental health issues.

In the study, the dogs used a long, black dog called Pippin.

The dogs were put in a three-dimensional box that was filled with objects that were different sizes and shapes.

They were trained on how to detect the difference in sizes and objects in the box.

The researchers tested four different dogs and found the dogs could discriminate between a long-haired person and a short-haired, medium-haired and long-hair person.

The short-hair dog, for example, was able to correctly identify the person from a distance, and the longer-haired dog was able the same thing.

Lohman said the training process is a bit more difficult than some other training methods that have been tried, but the results are significant.

“It’s not the only way to do it,” Lohmans said.

“There are other methods that you could use and it’s not just about a dog.

Lohmans is the lead author on the study and he and his colleagues said they are planning to continue to improve the dogs. “

If we could make it more effective for a wider population, it could be a big step in helping people.”

Lohmans is the lead author on the study and he and his colleagues said they are planning to continue to improve the dogs.

He said the researchers will now continue to train the dogs and the research is expected to be finished in 2019.
